Breather Fittings (Breathers)

Often referred to as Breathers or Air Vent Zerk Fittings, breather fittings are used with transmissions, differentials, speed reducers, axles, gear housings, and other mechanical devices. These particular grease fittings are designed to keep water and dirt from entering, while allowing air to escape, simultaneously.
