compression fittings, which ones should I get?

post #1 of 20
Thread Starter 
Im looking to make the move from barbs over to comp fittings. Right now Im using 7/16 x 5/8 tubing.

I want to know which size tubing/fitting combination is the most secure. Reason I ask this is I just bought 2 bp 7/16 comp fittings and the tubing fits over the barb part very snug like it should, but the part of the comp fitting that screws on that is supposed to be a retension device is not actually securing anything.

I put the tubing over the barb, and then I took the screw cap and put it on upside down to see if it would fit over the barb with the tubing on it. Sure enough it did with a tiny bit of room to spare. So if I use these comp fittings I will basically be using barbs with no clamps.

I want to try to avoid this if I can other wise I might as well stick with barbs and clamps.

Also, which brand is most preferred among ocn members?

You need to make sure the OD of the compression fittings and the tubing is the same I'm currently using BP fittings and they're great tbh.

Edit: I'm using 1/2" ID x 3/4" OD at the moment.

BP Black Sparkle 7/16" x 5/8" worked fine for me

Make sure you tighten it well, and try not to twist the tubing while tightening it either. otherwise the tubing might slip off.

You must have gotten the wrong ones. Either you ordered, company gave you, or the manufacture packaged them wrong.

I use Bitspower True silver fittings, with my 1/2 3/4 tubing and everything is tight. The tubing fits tight onto the "barb" and the ring fits tight onto the tubing around the barb. I just have to make sure not to tighten too much, as they are a pain to take off when over tightened.

I have Feser Silver fittings that I am going to add to my loop when I upgrade some. They feel great, but I havnt actually used them yet.

I also have some XSPC compression fittings, they are the cheapest in price and quality. I dont like them, but they do work.

well I bought them used from another ocn member. they are Bitspower True Silver fittings. maybe they are wrong size, but I dont think so.

Thing is it is almost a good fit, but not quite. I think they are the right size because the only other size it could be is 3/8x5/8 or 1/2x5/8


If it was 3/8 i wouldnt have been able to get the tubing on the barb. If it was 1/2 it would be alot more loose than it was.

The screw cap is touching the tubing, its just not holding it in place. I dunno, maybe its the tubing.
