CDI IN-LINE-AIR-CHECK-VALVE-12FPT Inline Air Check Valve

Industrial inline air check valve is a brass, inline one-way valve designed for air compressor lines with 12FPT (1/2" FPT) inlet and outlet. It includes a 1/8" FPT unloader port for venting and is suitable for vertical or horizontal installation to fit a variety of layouts. Marketed as a factory OEM part, it serves as a direct replacement in compressor assemblies, providing reliable backflow protection by allowing flow in only one direction and preventing reverse airflow from reaching the compressor or downstream equipment. The brass body and 12FPT connections support straightforward integration into standard air piping, offering durable performance in typical shop air environments and compatibility with common compressor circuits. This inline check valve helps maintain consistent downstream pressure as air is delivered, making it a practical component for routine maintenance, repairs, or upgrades of air handling systems.
