6 mm Zero Leak 316L Check Valve

This threadless, cartridge-style, one-way valve is made with an elastomeric seat for improved checked direction leakage performance. The valve features 316L stainless steel construction with a ceramic ball which provides compatibility with a wide range of aggressive fluids and gases, like hydrogen. This 6 mm valve features The Lee Company’s field-proven locking end that provides retention into metal manifolds without the use of threads, O-rings, or sealants. The valve is 100% performance tested.
