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

Duotight is a push fit with superior sealing capabilities due to its dual O-ring sealing design. Why do we use Double O-rings?The secret of our superior sealing performance is not only that we use high quality EPDM O-rings, but also two O-rings. The double O-ring means we literally have twice the sealing surface compared to other push fittings. This makes our equipment more reliable and greatly reduces the chance of leakage.The dual O-ring system also means that we can bend the pipe to a much tighter radius without causing leakage problems. This is often an issue with other devices. a mix of factors These make duo fittings the most reliable press fittings on the market. *The hose that fits the fitting is: EVABarrier 6.5mm (1/4") ID x 9.5mm (3/8") OD Line, double wall. (No clamp needed!)**It is recommended to cut the drain pipe straight, not at an angle, to ensure that the line is perfectly straight. in removing fittings Just press on the collar and the tube is removed.
