Check Valve

The Black Diamond® Check Valve is a genuine replacement part designed to ensure proper operation of your compressor system. Constructed from durable zinc plated steel, this valve closes securely after air is drained from the compressor head, preventing air from flowing back from the tank into the compressor. It features a 1/2 in. NPT x 1/2 in. tube connection with a 1/8 in. bleeder for reliable pressure control. Ideal for addressing air leaks or valves that fail to close properly, this replacement check valve helps restore dependable compressor performance.
