The Bendix 800533 is an ST-4 safety valve for air brake systems. It is a pressure-relief valve: if pressure climbs above its preset limit, the valve vents the excess air instead of letting it keep building. That protects the compressor and the brake components from the damage over-pressurization can cause.
It acts as a backstop on the air system, working only when pressure goes too high. A genuine Bendix part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
A factory handling fee of $20.00 per unit is added at checkout.
