John Guest Beer and Gas Line 5/16" OD x .187" ID

Made in the UK

Our recommended Beer and Gas line where you want an excellent quality line. Suits 5/16" John Guest speedfit fittings for the ultimate in adaptability and reliability.

We recommend use of the 3/8" John Guest LLDPE on the gas side for better compatibility with barbs  if they are used (Heavier wall thickness) or for use with 3/8" John Guest speedfit fittings for the ultimate in adaptability.

For most keg systems used at home a line length of 3m will give sufficient peripheral resistance to slow beer flow and avoid fobbing issues, while allowing a decent pour rate at 75kpa (10psi). Shorter line lengths can be used if the tap has flow control adjustment.
