duotight – 9.5mm (3/8”) Female x 9.5mm (3/8”) Female One Way Check Valve (Gas)

This very handy fitting could save your regulator and is a worthwhile, long-term investment for any setup. By preventing backflow, it acts as a critical line of defence against liquid travelling backward into delicate gas equipment, protecting your regulator from potential contamination and expensive fluid damage.

This particular type of check valve is engineered with a very low opening cracking pressure of only 1 psi, ensuring fluid or gas flows freely with minimal resistance and system restriction. Highly versatile in application, this check valve is suitable for clean liquids such as water as well as a wide range of gases. Furthermore, the internal spring and essential components are crafted from high-grade stainless steel, providing outstanding durability, corrosion resistance, and reliable performance even under continuous operational use.
