Duotight Food Grade Plastic (Push-In) Gas Check Valve - 5/16" (8mm)
Food Grade Plastic Duotight (Push-In) Gas Check Valve - 5/16" (8mm)
This check valve is made out of food grade plastic. It is perfect if you are not using a gas manifold with check valves. This push in valve protects your regulator against back flow and is meant to only be used on the gas side, it will not work with liquid. The red end is the output direction of the gas.

Duotight fittings are designed to work by simply pushing in the compatible tubing.

Inside each fitting are dual EPDM o-rings that provide superior sealing capacity due to having twice the sealing surface area when compared to other push in fittings. This makes Duotight fittings even more reliable and significantly reduces the chance of a leak.

For optimal performance it is recommended that when cutting your tubing it is cut straight, not on an angle, this helps to ensure a complete seal.

Meant to be used with 5/16" OD (8mm) EVABarrier & Polyethylene Tubing.
