5.5 mm Press-In LC Check Valve

This cartridge-style, non-return valve offers higher flow capacity over our standard 5.5 mm Press-In valves. This valve is specifically designed for installation into plastic housings and fittings. The valve can be installed in either direction, providing forward or reverse flow capabilities. Its all-stainless steel construction provides compatibility with a wide range of fluids and gases. A high quality metal-seat provides low leakage, a highly repeatable cracking pressure, and long life. The valve is 100% functionally tested to ensure performance.
