Cask Check Valve – 3/8" John Guest x 1/2" Barb Non Return Valve

Cask Check Valve – 3/8" John Guest Push-Fit x 1/2" Barb Outlet

This professional cask check valve (non-return valve) is designed for use in cask ale and beer dispense systems, helping to maintain consistent line pressure while preventing unwanted reverse flow through the dispense line.

Featuring a 3/8" John Guest push-fit inlet and 1/2" barbed outlet, it is quick to install and ideal for new installations, system upgrades and routine cellar maintenance.

Allowing beer or gas to flow in one direction only helps maintain a stable dispense system, supporting smoother pours and reducing the risk of pressure loss caused by backflow.

Whether you're maintaining a traditional pub cellar, installing a brewery dispense system or building a home cask setup, this compact check valve offers a simple and reliable solution.
