6 mm Zero Leak Press-In Check Valve

This cartridge-style, non-return valve is made with an elastomeric valve seat for improved checked direction leakage performance. The soft seat makes this check valve ideal for pneumatic applications where zero leakage is required or as a fill valve for gas systems. This valve is designed specifically for installation into plastic housings, fittings, or soft tubing. It can be installed in either direction, providing forward or reverse flow capabilities. The valve is 100% performance tested.

Key Product Facts
