Why is 7/16 tubing so hard to fit 1/2 barb? - Page 2

I got 3/8" tubing over 1/2" barbs by using just off boiling water handy as I made a cup of tea at the same time smile.gif

I fold 24/7 and have never had a barb pop off once. I also use two pumps in every single one of my loops so I have high pressure and flow. Use better tubing and/or barbs if you've had a problem.

Personally if your spending nearly $450 on the rad/pump/etc why wouldn't you just go all out and spend another $50 on compression fittings?

Im using primochill not cheap tubing and you dont look like your gpus are cooled im cooling cpu and a 5970 and 5870 so a ton of heat. My tubing didnt come all the way off but it did move but if you look on ocn people have had major leaks from not having clamps or wire ties even with good tubing once it heats up if their is any kind of bind it will slowly come off clamps or wire-ties cost a few bucks and are worth it to be safer.

LMAO... why won't my 1/2" barb fit into a 7/16 hole... lol.. a lot!

Immerse the pipe in boiling water for 10 seconds, and it will squeeze over the barb.

Easiest i have found is get your water to a boil and take some over to your pc in a coffee mug. Let the end sit in the water for about 10 seconds.

Btw might want to change title to..."Any tips for 7/16 ID over 1/2 barb" The way you have it now just sounds dumb..."Why wont my round peg fit in the square hole!!?!?!"

But seriously just use a bit of elbow grease (jabtech has it cheap) and heat the tube up.

As all the others have said, use some hot water or even a hairdryer to heat the end, then slide onto the barb. Try loosely screwing the barb into an unmounted (as in sitting on your desk) rad or block first to help hold it still. That might help. It shouldn't be too much trouble, although expect sore hands when you are done.


Putting 7/16" on a 1/2" barb isn't hard at all. Putting 3/8" on a 1/2" tube now, that is hard:

This was from an old temporary setup, now taken apart.

Weird I never really had this issue with primochill on multiple barbs. I did need to boil it to get it over a plastic "T".
