558 LC Series Check Valve

This threadless, cartridge-style, one-way valve offers higher flow capacity over our standard 558 Series valve. This valve features The Lee Company’s field-proven locking end that provides secure retention into metal manifolds without the need for threads, O-rings, or sealants. The valve features all stainless steel construction with a high quality metal seat providing low leakage, repeatable cracking pressure, and long life. The valve is 100% functionally tested to ensure performance.
