Duotight 8 mm Check Valve

Duotight check valve for 8mm EVAbarrier (5mm ID) or our John Guest 8mm (4mm ID) tubing. Typically used on the gas side of a keg system to prevent backflow of beer into the CO2 lines. The cracking pressure is about 0.07 bar.

The Kegland Duotight fittings use two EPDM O-rings in the fitting for a superior seal against the tubing and to allow a tighter bend radius at the fitting without leaking. They are rated up to 6.9 Bar, are made of food grade acetal plastic with a stainless steel lock ring, and are usable for both liquid and gas applications.

They work great with both the EVABarrier or John Guest LLDPE tubing.
