monotight – 6.35mm (1/4”) Female x 6.35mm (1/4”) Female One Way Check Valve (Gas)

This very handy fitting could save you your regulator and is a good investment. This particular type of check valve has low opening pressure of only 1psi.  This check valve is suitable for clean liquids such as water or for gas.  The spring and internal components are made with stainless steel.

This fitting is ideally used with 4mm ID x 6.3mm OD PE water line hosing

No clamps necessary!
We do recommend cutting your hosing straight, not on an angle, to ensure the line has a complete seal. To remove the fitting simply push in the collet and the hose can be removed. These push in fittings are suitable to be used up to 100 psi.
