Duotight – 8mm Push-Fit Check Valve
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.
Simple to use and requires no tools.
No clamps necessary, but 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 are push in fittings with superior sealing capacity due to the double o-ring sealing design. The secret is the high quality EPDM o-rings, two of them. The double o-ring means it has twice the sealing surface surface when compared with other push in fittings. This makes our fittings even more reliable and reduces the chance of a leak significantly. It also means the hose can bend with a much tighter radius without causing leaking issues.
Note: colour may vary.
