This brass 3-port air compressor check valve is a replacement for an old or broken non-return valve, with three male threaded connectors of 20mm, 19mm and 10mm that join the air line, the air tank and the compressor piston pump. It is a single solid brass fitting that screws straight into the existing connections.
Features and benefits:
- Brass body - a solid metal fitting for a part that sits in a pressurised air line
- Three male threaded ports - one each for the tube connection, the air pressure tank and the compressor piston pump
- Port sizes of 20mm, 19mm and 10mm - check these against the old valve before you order
- Threaded ends - the valve screws into place without any special fitting method
- Direct replacement - suits a worn or failed check valve of the same 3-port layout
- Single piece - one fitting to handle, with no loose parts in the pack
Applications:
- Replacing a failed check valve on a piston-type air compressor
- Workshop and garage compressor repair and servicing
- Rebuilding a compressor with a new tank to pump connection
- Spares for maintenance engineers who look after several compressors

A: It lets compressed air flow from the pump into the tank and stops it flowing back. This 3-port brass valve has separate male threads for the tube, the tank and the piston pump.. Q: How do I know if my air compressor check valve is bad? A: Common signs are the tank losing pressure when the compressor is switched off, or air leaking back through the pump side. If you see this, release the pressure and inspect or replace the valve.. Q: What thread sizes does this check valve have? A: The listing gives three male thread diameters: 20mm, 19mm and 10mm. The images show a 20mm bottom port, a 10mm port and a 19mm side port height.. Q: Which port goes where? A: The three male connectors are for the tube connection, the air pressure tank and the compressor piston pump. Match each port to the old valve before fitting.. Q: What is the valve made of? A: The material is brass, as published by the seller..
