Responsive pressure equalization and robust contaminant protection can extend the reliability and lifespan of oil-filled drivetrains, transmissions and e-motors.

Why use a quality gearbox vent in heavy-duty equipment?

Drivetrains and oil-filled gearboxes are used in heavy-duty equipment, rail, marine and new energy applications like wind turbines. To keep running, they all demand reliable, durable protection from pressure imbalances, leaks and contaminant ingress.

Gore’s Gearbox Vents provide that protection, to extend component life.

Engineered to enhance the longevity of critical components

  • Solid Beam
  • Rear/Front Drive Module
  • e-Axles
  • Oil-cooled e-Motor

GORE Protective Vents for Gearboxes outperform open tubes or rattle caps, and standard membrane vents, because they:

Block contaminants

Effectively block contaminants that can degrade gears or cause electric arcs in e-motors: Water, dust and dirt — which degrade traditional vent performance — can’t penetrate Gore’s breathable barrier membrane.

Protect seals

Protect seals from stress/failures: Our gearbox vent has bi-directional breathability. Even during extreme temperature or altitude changes, it continuously equalizes overpressures and vacuums, to preserve seals and protect against leakage or contaminant ingress.

Prevent oil leaks and damage

Prevent oil spills & leaks; limit damage & clogs from oil aerosols: Unlike open tubes/rattle caps, GORE Gearbox Vents are leak-proof. And they trap aerosols that rapidly compromise ordinary membrane vents.

Extend gearbox life-span

Extend gearbox life-span: OEMs worldwide trust the proven performance of these GORE® Vents, with their exceptional chemical, mechanical and temperature resistance over time, and rating to IP68 and IP69k.

Lower Total Cost of Ownership

Enable lower Total Cost of Ownership (TCO): These tube-mount gearbox vents can streamline engineering design as well as purchasing, inventory and installation, for lower TCO.
