What is the OD?
Benson Wills on Jul 18, 2018
BEST ANSWER: Hello Benson - The OD of TUB411 is 9/16" as printed on the tubing.
Has anyone used this on 1/4 inch barb instead of a 5/16 inch barb ?
Keith Kimes on Oct 26, 2019
BEST ANSWER: I tried a 1/4 inch barb and it isn’t tight enough. Go with the 5/16 barb. Before you place it in, soak the tube tip in warm water for 3 min. and slide it in. I always use a small stainless steel clamp for extra security.
What stepless clamp size fits this 9/16" OD line?
Daniel Torres on Jun 17, 2020
BEST ANSWER: For 9/16" OD tubing you will need the stepless clamp for 5/8" (H1004). 9/16" tubing is 0.563" and that clamp has a minimum od of 0.551".

PVC free tubing - 5/16"
Fantastic, strong tubing.

Work well
Replaced my old standard gas lines with these a while ago; the transfer was easy however the ID on either my old lines or these were slightly off. The lines I replaced were marked 5/16 however were apparently smaller than these since these did not fit as tightly to the same fittings. Using simple clamps and tightening them down worked well and I have not had any gas leaks however the soft material of these tubes make it easy for the clamps to dig into the outside of the tube.

All and all very happy with these tubes, just wish I'd had a caliper handy to measure the old ones vs. new ones.
