Duotight - 8 mm (5/16") x One way check valve
The check valve, also known as a backflow preventer, ensures that gases or liquids only flow in one direction and cannot flow back. Check valves open automatically as soon as a liquid or gas flows. As soon as the direction of flow changes, the valve closes.
The quick coupling has an outside diameter (OD) of 8 mm (5/16 ") on each side. The opening pressure is 0.07 bar (equivalent to 1 psi). The valve is suitable for liquids such as water or gas. The springs are Made of stainless steel and high quality ethylene-propylene-rubber seals. No clamps are required. It is recommended that the hose be cut straight, not at an angle, in order to ensure a complete seal of the line.
To remove the fitting, simply push in the collet and the hose can be removed. The push-in fitting is suitable for use up to 6.8 bar (corresponds to 100 psi).
This push-in fitting is designed for maximum performance in both gas and liquid applications. Compared to other hose connections on the market, Duotight offers double security for all connections with two ethylene-propylene-rubber O-rings per hose connection.
