8 mm Insert Side Exit Check Valve

This threadless, cartridge-style, one-way valve offers side-exit flow. The inlet and outlet are not on the same axis, so flow follows a 90° angle. 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 for low leakage, repeatable cracking pressure, and long life. The valve is 100% functionally tested to ensure performance.
