2.5 mm 316L Press-In Check Valve With Ceramic Ball

This cartridge-style, non-return valve is designed specifically for installation into many common medical fittings and plastic housings. The valve can be installed in either direction, providing forward or reverse flow capabilities. 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. A high quality metal seat provides low leakage, repeatable cracking pressure, and long life. The valve is 100% functionally tested to ensure performance.
