John Guest 3/8" and 3/16" ID beer lines

Hi folks

I have JG 3/8" OD connects on tap shank and kegs.
My local store only sells a super thin-walled line with very low resistance and I am building a kegerator.

Is there a line that is 3/8" OD but 3/16" ID?

I had seen that some lines are supposed to fit these JG fittings but are 7/16" OD . . . ?

JG fittings are pretty limited in the 7/16 od sizing. I believe most people use the 5/16 OD Bevseal ultra lines with JG fittings.


Here are a couple options that should work with your 3/8" OD fittings.

I bought 3/8 JG fittings for my kegerator setup just recently. They work great. The best deal I found was on amazon

I also have 3/8 to 1/4 FFL fittings to connect my lines to the ball valves, also from Amazon. I figured this was the best way to connect equipment to my bev-seal ultra lines. You won't be disappointed.

Ok, so there ARE thick-walled options out there ... just gotta see what I can get out here!

@jddevinn, I have not been able to find that super-sweet ultra line here. What I found here that fits the 3/8" OD of the JG looks similar, but is green and the ID is huge (i.e. hilariously low resistance).

Thanks people!
All else failing, I will have my folks bring a reel with them in September of the bev-seal ultra.
