2.5 mm Press-In Check Valve

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 all stainless steel construction which provides compatibility with a wide range of fluids and gases. In addition, it is available with a ceramic ball for improved corrosion resistance. A high quality metal seat provides low leakage, repeatable cracking pressure, and long life. The valve is 100% functionally tested to ensure performance.
