1/2" Flare x 1/2" Male NPT Air Compressor Check Valve In Tank Brass

1/2" Flare x 1/2" Male NPT Air Compressor Check Valve, In-Tank with 1/8" Female NPT Port for Unloader

Keep your air compressor system running smoothly with this replacement 1/2" flare x 1/2" male NPT check valve. Designed to be screwed directly into the air tank, this check valve serves as a one-way valve that prevents backflow or tank pressure from returning to the compressor pump after the compressor is shut off. This simple yet effective valve ensures that your compressor operates efficiently and remains in top condition by maintaining the proper flow and pressure.

This valve includes a 1/8" female NPT side port, typically used for connecting to an unloader valve on the pressure switch or compressor pump. If your compressor does not use an unloader system, this port can be easily sealed with a plug, ensuring the valve functions as needed.
