KeyKeg coupler with PRV pressure‑relief valve

This KeyKeg coupler with PRV is designed for KeyKeg kegs using the Twist coupling system. It features a 5/8" BSP inlet and outlet, allowing standardized connection to professional installations.

The coupler is supplied with two 8 mm x 5/8" duotight fittings, a Torpedo cap with its retaining system, as well as a one-way silicone gas valve. The manufacturer specifies that the washer must be removed on the gas side, with the duckbill valve ensuring the seal.

The coupler can be used with different EVABarrier tubing diameters depending on the beverage type: 4 mm x 8 mm for beer and cider, 5 mm x 8 mm for cocktails and still wines. For higher flow rates, the outlet duotight fitting can be replaced with a 9.5 mm x 5/8" model and an EVABarrier 6.3 mm x 9.5 mm tube.
