    Overview

    Each application has its own set of challenges, such as exposure to temperature changes, environmental conditions like water, dust, dirt and debris or even contact with automotive fluids including urea solutions, car wash fluids, and lubricants. Without the correct venting solution in place, these challenges can impact reliability and durability. Our vents quickly equalize both over-pressures and dangerous under-pressures that could pull water, contaminants and condensation into the housing and onto the sensitive electronics. More reliable venting performance can reduce the need for heavier housings, seals and gaskets, so component design is less complex, manufacturing costs and time to market is reduced.

    Engine Control Units 

    High-value control units are challenged by harsh under-hood environments, where these sensitive units are exposed to temperature extremes and contamination by automotive fluids or water spray. Snap-Fit Vents excel at protecting critical engine control units from environmental contaminants, while providing rapid air exchange to ensure long-term venting reliability.

     


     

    Wiper Motors 

    Wiper motors are critical to driver safety, yet their durability can be threatened by anything from extreme weather to owner-applied cleaning agents or high-pressure steam jets. In an increasingly cost-sensitive environment, OEMs require more effective venting to protect and extend the service life of wiper motors, reducing warranty claims.

     


    ABS Control Units

    Safety-critical ABS control units must be vented reliably for the life of the unit. Exposure to temperature fluctuations created by the engine block or exhaust system, or normal under-the-hood contaminants, can cause ordinary vents to fail. Automotive Vents—engineered specifically for these applications—are performance-tested to ensure reliability and longevity. Our Weldable and Snap-Fit Vents effectively equalize pressure and block contaminants, reducing warranty issues.

     


    Battery Packs ⁄ Battery Boxes

    The large internal volume of battery packs and boxes makes them extremely sensitive to temperature changes. These temperature changes can cause pressure buildups or vacuums that can stress seals and draw contaminants into the housing. Challenging environmental and operating conditions from automotive fluids to ice, mud, salt water and road debris, can further reduce battery pack longevity and performance. Our portfolio of High-Airflow venting products provides the optimal balance of pressure management and barrier protection, so unit designs can be simplified and light-weighted, material and production costs can be lowered, and warranty claims can be reduced.

     


    Oxygen Sensors

    To withstand operating temperatures that can exceed 250 °C, oxygen sensors require extremely efficient venting with high airflow for rapid pressure equalization. At the same time, the vent must effectively protect the sensor from being contaminated by water, dirt, and other particulates. Our high-temperature oxygen sensor tube vents are specifically engineered to perform in just these conditions. Made of 100% ePTFE, they are designed, tested, and proven to provide rapid response and reliable protection.
