Draught Equipment and System Configuarations > Essential Draught System Components > Gas Line
Gas line should be selected to withstand the pressures expected in the draught system. We saw that vinyl tubing often serves as beer line and vinyl of some type often serves as gas line. Often vinyl gas line has greater wall thickness than vinyl beer line. To help distinguish between gas line and beer line, colored vinyl is used for CO2 supply lines in some systems. But clear vinyl may be used as it aids in troubleshooting by allowing you to see if beer has escaped the coupler and entered the gas line due to a faulty or missing Thomas valve.
Braided vinyl is often used for CO2, particularly in high pressure situations (50+ psi) and in long CO2 runs. Braided vinyl is commonly used in soft drink lines for both beverage and gas.
