Toyota case study powertrain

Learn why Toyota Motor Corporation chose to partner with GORE® Automotive Vents when other venting solutions could not meet Toyota’s performance requirements for a new e-axle containing lubricated gears and a higher-voltage e-motor. This Case Study outlines the associated challenges, solution and results — including an on-time product launch for Toyota.

This document provides performance characteristics and specifications for GORE® Automotive Vents AVS 22 and AVS 23, suitable for rear lamps. Featuring a laminate construction, these low-profile adhesive vents provide a secure bond to the housing.

NEMA Ratings and What They Mean

Technical Information

A critical aspect of vent selection begins with defining the level of protection your application, device or housing requires.

IP ratings cannot be “converted” to NEMA ratings, since NEMA requires additional testing not included in IP. However, there are minimum NEMA ratings that will meet or exceed a given IP code.

Drive Line - Tube-Mount AVS 41

Designed for high performance in both electrified and traditional Powertrain components. These compact and waterproof tube-mount vents provide responsive pressure equalization and reliable ingress protection that complies with global OEM standards including water wading, vehicle rollover and fluid containment.
