DUOTIGHT - 8MM(5/16) X ONE WAY CHECK VALVE/NON-RETURN VALVE [Check Valve]
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 and quality EPDM seals.
This fitting is ideally used with EVABarrier 5mm x 8mm or EVABarrier 4mm x 8mm
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 psiThese push in fittings have been engineered for maximised performance in both gas and liquid applications. Compared to other push in fittings on the market, duotight takes the double safety approach to all of the connections with two EPDM o-rings per hose port. No other push ins on the market have EPDM o-rings, let alone two! per push in connection.
