Duotight push fit shutoff valve for 9.5 mm tubing. For gas and liquids. The 9.5mm EVAbarrier (6.3 mm ID) tubing works great with this fitting.
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.
