Create your own custom-fit gas line with this 1/4" ID Tubing.
This diameter of tubing will give you an extra-tight fit gas line, particularly with homebrew quick disconnects. Simply soak the 1/4" line in hot water before attaching to larger 5/16" fittings. It is also well suited for beer lines that are 10-25' in length.
Technical Specifications: 1/2" Outer Diameter. 1/4" line provides .65 lbs of restriction per foot. Ideally pounds of resistance should equal pounds of applied pressure. 1/4" line holds 1/3 of an ounce per foot. Made from PVC.
