This very handy 8mm (5/16) One Way Check Valve fitting could save your regulator and is a sound and small investment. This particular type of check valve has low opening pressure of only 1 psi.  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 psi

These 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 that we are aware of have EPDM o-rings, let alone two! per push in connection.

What is EPDM?
EPDM = Ethylene Propylene Rubber which has excellent chemical resistance including being compatible with ozone, oils, wide variety of alkaline and acid compounds, water, alcohol, ketone and beverages.

EPDM is also resistant to ageing, weather and will not perish easily like other rubber compounds.   When compared with silicon and vinyl EPDM has better gas transmission rates, better wear resistance, is BPA free and is the number one choice for many long lasting food grade applications.
