The One Way Check Valve has a low opening of 1psi and is suitable for use with gas. Due to the fact that this check valve cannot be taken apart to clean, it is not recommend for use with liquid.

This fitting is NOT compatible with 8mm OD EVABarrier line with a 4mm or 5mm ID. There are other DuoTight Fittings that are sold separately for this application.

The secret to the superior sealing performance is not just the fact that a high quality EPDM O-Ring is used but there are two of them. The Double O-Ring means that there is literally have twice the sealing surface when compared with other push in fittings.
This makes the DuoTight fittings even more reliable and reduces the chance of leakages significantly.
The Double O-Ring System also means that a tube can be bend in a much tighter radius without causing leaking issues.
No clamps required.
EPDM Rubber:
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 aging, 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.
