Duotight 8mm (5/16) one way check valve/non-return valve.
This very handy fitting could save your regulator and is a good investment. This particular type of check valve has low opening pressure of only 1 psi. It is suitable for clean liquids such as water or for gas. The spring and internal components are made with stainless steel and quality EPDM seals.
No clamps necessary, however 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. These push in fittings have been engineered for maximised performance in both gas and liquid applications. Duotight takes the double safety approach to all of the connections with two EPDM o-rings per hose port.
Fits 8mm outer diameter tube.
Note: colour may vary.
