Bendix 800490 single check valve SC-3, an air brake reservoir check valve and a genuine Bendix part from Pro Gear and Transmission. An in-line check valve sits in an air line and passes air in one direction only, then seals shut so the air cannot flow backward.
Air moving the normal way lifts the valve element off its seat, and a drop in pressure upstream lets it seat again and hold the air in. A check valve that leaks, or shows wear or deterioration, is due for replacement. Call us with your application and we will help confirm proper fit.
A factory handling fee of $20.00 per unit is added at checkout.
