commercial vehicles, service fleets, agricultural machinery, or marine equipment, you know that enclosure protection matters as much as electrical performance. A waterproof DC\u2011DC converter with the wrong IP rating can fail prematurely from dust, moisture, or temporary immersion. This guide compares IP67 vs IP68 protection to help you select the right rating for each vehicle installation. WEHO designs vehicle\u2011mounted DC\u2011DC converters for demanding environmental conditions.

The first digit \u201c6\u201d means the equipment is dust\u2011tight: no dust can enter the enclosure under defined test conditions. The second digit \u201c7\u201d means the equipment can withstand temporary immersion in water up to 1 meter deep for up to 30 minutes. For many vehicle\u2011mounted DC\u2011DC converters, IP67 is a practical baseline for harsh but not continuously submerged environments.<\/div>\n<\/div>\n<div>\n<div>In transportation applications, IP67 is commonly associated with protection against high\u2011pressure water spray, road splash, rain, and temporary exposure to standing water. If a converter is mounted in an area that occasionally gets wet during cleaning, rain, or flooding, IP67 can provide a strong balance of protection and cost. WEHO offers IP67\u2011rated modules inside our <a title=\"\" href=\"https:\/\/www.wehopower.com\/ur\/product_categories_new\/power-supply\/\" target=\"_blank\" rel=\"noopener\">\u0628\u062c\u0644\u06cc \u06a9\u06cc \u0641\u0631\u0627\u06c1\u0645\u06cc<\/a> product portfolio for vehicle locations where waterproof performance is required but permanent immersion is not part of the expected service profile. When you retrofit onboard power systems, you should pay attention to both environmental sealing and electrical parameters during component selection.<\/div>\n<\/div>\n<div>\n<div>Many fleet procurement teams prefer IP67 units for general under\u2011hood and chassis mounting scenarios. It handles daily road grime, rain splash and occasional high\u2011pressure wash well, without paying extra cost for higher\u2011grade sealing that will never be required in real\u2011world operation. For most land\u2011based commercial vehicle projects, IP67 delivers sufficient reliability under normal service cycles.<\/div>\n<div>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-17465\" title=\"weho\u2011ip67\u2011waterproof\u2011dc\u2011dc\u2011converter\u2011spray\u2011test\" src=\"https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/weho\u2011ip67\u2011waterproof\u2011dc\u2011dc\u2011converter\u2011spray\u2011test.png?quality=85&strip=all\" alt=\"WEHO IP67 waterproof DC\u2011DC converter under water spray test for vehicle fleet application\" width=\"817\" height=\"429\" srcset=\"https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/weho\u2011ip67\u2011waterproof\u2011dc\u2011dc\u2011converter\u2011spray\u2011test.png?quality=85&strip=all 817w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/weho\u2011ip67\u2011waterproof\u2011dc\u2011dc\u2011converter\u2011spray\u2011test-300x158.png?quality=85&strip=all 300w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/weho\u2011ip67\u2011waterproof\u2011dc\u2011dc\u2011converter\u2011spray\u2011test-768x403.png?quality=85&strip=all 768w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/weho\u2011ip67\u2011waterproof\u2011dc\u2011dc\u2011converter\u2011spray\u2011test-18x9.png?quality=85&strip=all 18w\" sizes=\"(max-width: 817px) 100vw, 817px\" \/><\/p>\n<\/div>\n<\/div>\n<div>\n<h2><span class=\"ez-toc-section\" id=\"What_Is_IP68_Protection_for_DC%E2%80%91DC_Converters\"><\/span>What Is IP68 Protection for DC\u2011DC Converters?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<\/div>\n<div>\n<div>IP68 is the higher ingress protection level for permanent or more demanding water exposure. The first digit is still \u201c6,\u201d so the enclosure remains dust\u2011tight. The second digit \u201c8\u201d means the equipment is suitable for continuous immersion in water under conditions that are agreed between manufacturer and customer, typically beyond 1 meter and 30 minutes. In practice, an IP68 DC\u2011DC converter is expected to handle sustained wetting, deeper temporary flooding, and more severe washdown procedures.<\/div>\n<\/div>\n<div>\n<div>For vehicle and industrial integrators, IP68 is often chosen when equipment will be exposed to heavy water ingress, frequent high\u2011pressure cleaning, underbody splash zones, or installation near water\u2011handling components. It is not automatically required for every automotive application, but it is an important rating for high\u2011risk locations. Harsh working environments also require reliable backup power solutions, which we cover in our article about <a title=\"\" href=\"https:\/\/www.wehopower.com\/ur\/news\/uninterruptible-power-supplies-ups-a-switching-power-supply-perspective\/\" target=\"_blank\" rel=\"noopener\">uninterruptible power supplies<\/a>. WEHO\u2019s IP68\u2011capable vehicle\u2011mounted power modules belong to our waterproof power series, built for installations where waterproof reliability is critical. Even with top\u2011tier IP68 sealing, you still need to validate output current, efficiency and protection features.<\/div>\n<\/div>\n<div>\n<div>Keep in mind that IP68 certification always comes with manufacturer\u2011defined depth and time limits. Not all IP68 power supplies support identical immersion depth and duration. As a buyer, you must double\u2011check manufacturer test parameters instead of relying only on the IP logo printed on the housing. Misjudging actual immersion limits can still lead to unexpected field failures.<\/div>\n<\/div>\n<div>\n<h2><span class=\"ez-toc-section\" id=\"IP67_vs_IP68_Key_Differences_for_Vehicle_Applications\"><\/span>IP67 vs IP68: Key Differences for Vehicle Applications<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"Water_Immersion_Depth_and_Duration\"><\/span>Water Immersion Depth and Duration<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<div>\n<div>The most important difference between IP67 and IP68 is water immersion capability. IP67 allows temporary immersion up to 1 meter for 30 minutes. IP68 allows immersion beyond that limit, with the exact depth and duration specified by the manufacturer. For vehicle applications, this means IP68 offers a larger safety margin if the unit is installed in a location that may be flooded for longer periods.<\/div>\n<\/div>\n<div>\n<div>If your equipment operates in an environment where underbody flooding, deep splash, or high\u2011pressure washdown is common, IP68 reduces the risk of water ingress. If the installation area is occasionally wet but not subject to prolonged immersion, IP67 may be sufficient. WEHO can help you evaluate which waterproof DC\u2011DC converter rating matches your actual exposure level.<\/div>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"Dust_and_Particle_Resistance\"><\/span>Dust and Particle Resistance<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<div>\n<div>When comparing IP67 vs IP68, dust resistance is identical at the first digit level: both ratings require a dust\u2011tight enclosure. That means neither rating allows harmful dust accumulation inside the unit under standard test conditions. For vehicle applications where road dust, construction dirt, and agricultural debris are present, both IP67 and IP68 can provide strong dust protection.<\/div>\n<\/div>\n<div>\n<div>The practical difference is therefore more about water than dust. However, a higher IP rating usually requires more robust sealing around connectors, housings, and cable entries. WEHO ensures that its vehicle\u2011mounted DC\u2011DC converters maintain reliable sealing in real\u2011world vibration, temperature cycling, and moisture exposure.<\/div>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"Typical_Mounting_Locations\"><\/span>Typical Mounting Locations<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<div>\n<div>IP67 is often suitable for protected underhood areas, chassis locations with moderate splash, control cabinets, and equipment compartments that are not permanently exposed to standing water. IP68 is more appropriate for unprotected underbody positions, areas subject to heavy flooding, marine\u2011grade installations, and equipment that undergoes aggressive washdown.<\/div>\n<\/div>\n<div>\n<div>Choosing the right rating depends on the mounting location and maintenance practice. A converter installed inside a dry cabin or protected control box may not need IP68, while one mounted near the wheels or under the chassis may benefit from the higher waterproof level. WEHO recommends integrators map each installation location to its exposure risk before selecting a rating.<\/div>\n<div>\n<p><img decoding=\"async\" class=\"size-full wp-image-17464\" title=\"weho\u2011ip67\u2011industrial\u2011waterproof\u2011power\u2011supply\u2011unit\" src=\"https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/weho\u2011ip67\u2011industrial\u2011waterproof\u2011power\u2011supply\u2011unit.png?quality=85&strip=all\" alt=\"WEHO IP67 sealed industrial waterproof power supply unit for marine and agricultural heavy\u2011duty equipment\" width=\"550\" height=\"550\" srcset=\"https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/weho\u2011ip67\u2011industrial\u2011waterproof\u2011power\u2011supply\u2011unit.png?quality=85&strip=all 550w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/weho\u2011ip67\u2011industrial\u2011waterproof\u2011power\u2011supply\u2011unit-300x300.png?quality=85&strip=all 300w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/weho\u2011ip67\u2011industrial\u2011waterproof\u2011power\u2011supply\u2011unit-500x500.png?quality=85&strip=all 500w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2026\/09\/weho\u2011ip67\u2011industrial\u2011waterproof\u2011power\u2011supply\u2011unit-12x12.png?quality=85&strip=all 12w\" sizes=\"(max-width: 550px) 100vw, 550px\" \/><\/p>\n<\/div>\n<\/div>\n<div>\n<h2><span class=\"ez-toc-section\" id=\"IP67_vs_IP68_Vehicle_Application_Comparison_Table\"><\/span>IP67 vs IP68 Vehicle Application Comparison Table<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<\/div>\n<div>\n<div>\n<div>\n<div>\n<div>\n<div>\n<table>\n<thead>\n<tr>\n<th>Evaluation Factor<\/th>\n<th>IP67 DC\u2011DC Converter<\/th>\n<th>IP68 DC\u2011DC Converter<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Dust Protection<\/td>\n<td>Dust\u2011tight<\/td>\n<td>Dust\u2011tight<\/td>\n<\/tr>\n<tr>\n<td>Water Immersion<\/td>\n<td>Temporary immersion up to 1m for 30 min<\/td>\n<td>Continuous immersion beyond IP67 limits<\/td>\n<\/tr>\n<tr>\n<td>Best For<\/td>\n<td>Occasional rain, splash, and moderate washdown<\/td>\n<td>Heavy splash, prolonged flooding, high\u2011pressure cleaning<\/td>\n<\/tr>\n<tr>\n<td>Typical Locations<\/td>\n<td>Protected underhood, control cabinets, moderate\u2011splash chassis areas<\/td>\n<td>Underbody, marine equipment, agricultural machinery, high\u2011washdown zones<\/td>\n<\/tr>\n<tr>\n<td>Procurement Consideration<\/td>\n<td>Lower cost of ownership for suitable locations<\/td>\n<td>Higher upfront cost but larger ingress protection margin<\/td>\n<\/tr>\n<tr>\n<td>WEHO Recommendation<\/td>\n<td>Select when waterproof performance is needed without permanent immersion<\/td>\n<td>Select when sustained wetting or deep temporary immersion is expected<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div>\n<h2><span class=\"ez-toc-section\" id=\"Choosing_the_Right_Protection_Level\"><\/span>Choosing the Right Protection Level<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"On%E2%80%91Road_Vehicles_and_RVs\"><\/span>On\u2011Road Vehicles and RVs<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<div>\n<div>For on\u2011road vehicles and RVs, IP67 is often enough if the converter is mounted in a protected area.

These vehicles often operate in muddy, dusty, and wet conditions, and cleaning procedures can be aggressive. A waterproof DC\u2011DC converter with IP68 capability is better prepared for sustained moisture exposure.<\/div>\n<\/div>\n<div>\n<div>Even in these environments, IP67 may still work if the unit is well\u2011protected. But for high\u2011risk installations, the extra margin of IP68 can reduce field failures and warranty costs. WEHO supports industrial buyers by providing application\u2011specific guidance on IP ratings for heavy\u2011duty projects.<\/div>\n<\/div>\n<div>\n<div>Before finalizing your component list, evaluate your real\u2011world operating scenarios rather than simply choosing the highest IP grade available. Over\u2011specifying protection increases material cost, while under\u2011specifying leads to expensive on\u2011site repair and replacement work.<\/div>\n<\/div>\n<div>\n<h2><span class=\"ez-toc-section\" id=\"Why_Choose_WEHO_as_Your_Partner\"><\/span>Why Choose WEHO as Your Partner<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<\/div>\n<div>\n<div>Selecting between IP67 and IP68 is not just about reading the second digit of the rating. You also need to consider mounting position, exposure severity, maintenance procedures, thermal performance, and long\u2011term reliability. WEHO helps procurement teams translate those conditions into the right vehicle\u2011mounted DC\u2011DC converter solution.<\/div>\n<\/div>\n<div>\n<div>WEHO\u2019s IP\u2011rated power modules are designed for tough transportation environments, with robust enclosures, sealed connections, and protection against dust and water ingress. By choosing WEHO, you get more than a waterproof DC\u2011DC converter; you get support for application assessment, product selection, and documentation.

Both ratings are dust\u2011tight, but IP67 allows temporary immersion up to 1 meter for 30 minutes, while IP68 allows deeper or longer immersion under manufacturer\u2011specified conditions.<\/div>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"Do_I_need_IP68_for_an_underbody%E2%80%91mounted_converter\"><\/span>Do I need IP68 for an underbody\u2011mounted converter?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<div>\n<div>Not always, but IP68 is often recommended for underbody converters because of exposure to road splash, dirt, moisture, and high\u2011pressure cleaning. If the location is frequently wet or flooded, IP68 provides a higher safety margin.<\/div>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"Can_an_IP67%E2%80%91rated_converter_be_used_in_wet_environments\"><\/span>Can an IP67\u2011rated converter be used in wet environments?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<div>\n<div>Yes, an IP67\u2011rated converter can be used in many wet environments, including rain, splash, and temporary moisture. It should not be used for continuous immersion or applications that exceed its waterproof rating.<\/div>\n<\/div>\n<div>\n<h3><span class=\"ez-toc-section\" id=\"Is_IP68_overkill_for_standard_automotive_use\"><\/span>Is IP68 overkill for standard automotive use?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<\/div>\n<div>\n<div>IP68 can be overkill for protected installations such as dry control boxes or covered underhood areas. For standard automotive use in protected locations, IP67 is often sufficient and more cost\u2011effective.<\/div>\n<\/div>\n<div>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>\u0646\u062a\u06cc\u062c\u06c1<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<\/div>\n<div>\n<div>Choosing between IP67 and IP68 for vehicle\u2011mounted DC\u2011DC converters depends on water exposure, mounting location, dust exposure, and maintenance practices. IP67 is strong for temporary moisture and moderate splash, while IP68 offers extra waterproof reliability for harsher environments. For procurement teams, the goal is to match the IP rating to the actual installation risk rather than automatically selecting the highest level.
