Air Vent Grease Fittings

Vent fittings, also referred to as air vent fittings, control pressure build up in a lubricated assembly by opening and closing in a pre-determined pressure range. As pressure increases, the spring loaded valve opens to allow pressure build up to escape. As pressure returns to the desired threshold, the valve closes. The unique design of vent fittings protects against moisture and debris from entering an assembly.
