Default 5/16 gas line to 1/4 barb fittings

I got a 1/4" cross fitting to split my gas line to 3 kegs. I've got the original keg with MFL Ball lock disconnects on the 5/16 line connected to the regulator. However, my new hardware are two 1/4" barbed disconnects and 1/4" line with the 1/4" fitting. I've got plumbers lube and a bunch of worm gear clamps.

Can I clamp the crap out of the 5/16 line and make it work with the smaller 1/4 fittings or do I need to go back to the drawing board?

Anyone else have experience with this one?

I have not had this problem however I would still try it out. The real problem would be leaks and if you keep your eyes on it (leak check everything) I would have to say you could make it work.

Hose is cheap.... 1/4 hose would make me rest easier personally.

Me too. But the problem starts with the 5/16 thick red line coming off the regulator (original equipment on the kegerator). I don't think I could hook up 1/4 hose to the regulator fitting.

perhaps try using a short 1/2" piece of the 1/4" line on the barb and then slip the 5/16 over that. Heat the 5/16 if it is a tough fit.

I would just buy new barbs. Cheap and puts my mind at ease.

[edit] Nevermind, I didn't realize your new hardware was barbed QDs and not threaded with a swivel nut. In that case, I'm clueless short of investing in new threaded QDs with the proper swivel nuts with 5/16 barbs.

I had this same problem when I first got my keg. 5/16th gas hose to a 1/4 disconnect. I clamped the hell out of it and it fit on the 1/4 inch. It sealed pretty tight but looked a bit loose, so I came across a 5/16th to 1/4 splicer and used that with no problems.

Teflon sounds like an idea, If you clamp it down hard enough should do the trick.

I've got the smaller barbs on some of my gas tubing. Just clamped them down real tight and haven't had any issues.

Why not just buy a reducer 5/16" to 1/4". I have 5/16 and 1/4 both coming off my regulators. Just need the correct fittings.

Otherwise just clamp it and check for leaks. I do have one 5/16 on a 1/4 bard, no issues.
