Compression fitting questions

post #1 of 13
Thread Starter 
Hello all. Of course these question will alert you to my newbness so, sorry in advance.

1. Are compression fittings equal to or better than using barbs and clamps? What I mean is do compression fitting replace the need for barbs and clamps.
2. Are compression fittings really worth their cost? or is it more of an aesthetic thing?
3. When using a compression fittings what are the sizes to use? Like if I get a 1/2 compression fitting then what size tube to I use?

Its a personal preference if you want to spend the money for them. Their more for aesthetics. IMO I think their easier to deal with, not having to use clamps or zip-ties. But you can also use 1/2" barbs and use 7/16" ID tubing and not use any clamps, the seal is so tight you dont need to worry about it.

Performance difference, there isnt one.

I keep on hearing people say use 1/2 barbs and 7/16 tubing with no clamps. Something about that never sits right with me. But maybe it's because I haven't actually touched a water cooled rig and can witness how tight it is.

Barbs and clamps will yield the same performance, but in my opinion, compression fittings are worth the extra couple of bucks. They feel much more secure than a barb to the point where I could actually pick up my rig by the water cooling hoses (though not recommended!!). It is overkill for sure, but I like the way they look (more "finished" looking) and the peace of mind they provide.

As for sizes, compression fittings have two size specifications, such as "3/8 ID (inner diameter) 5/8 OD (outer diameter)". Use the size that corresponds to the specifications of your tubing.

Compression fittings are for bling factor only.


By dipping the end of 7/16" tubing in boiling water and then pushing it over a 1/2" barb, you're effectively creating a leak-proof connection that will only be removed by cutting...you can always add a zip-tie/clamp for extra security, but it's generally not needed.

Bling, but they do work perfectly well. I use several in my loop. I'd call them just as good as barbs in actual use.
