One-way flow is the key feature of the Bendix Air Brake Reservoir Check Valve, a single check valve that lets air into a reservoir but stops it from flowing back out. That one-way action keeps the reservoir behind the Bendix 800375 charged if pressure drops upstream, so a supply-line leak does not drain the tank. Installing it with its flow arrow pointing toward the reservoir is the key step during a swap. A quick soap test on the fittings after the system recharges confirms there are no leaks.
