The Jflex 1/2" Non Return Valve with Unloader is a premium brass fitting designed specifically for air compressor receiver tanks. It combines a non-return valve and an unloader port into one compact unit, helping to maintain consistent air pressure and safely release head pressure during shut-off. The valve features a 1/2" BSP bottom feed, a 1/8" BSP female unloader port (complete with connector and olive for 6mm tubing). This makes installation into most common compressor setups quick and reliable. Crafted from corrosion-resistant brass for durability in high-moisture air systems, it’s ideal for use in industrial and trade applications.
