Question by: Kurt W on Jun 29, 2025, 7:58 AM

So, this is just the sleeve, right? Not the whole fitting?

Answer by: Customer Support on Jul 1, 2025, 7:00 AM

That's correct. It's just the stainless steel sleeve for a 0.63 inch tube OD with a female JIC 37 degree flare.

Question by: Harold B on Nov 22, 2025, 7:56 PM

got a 5/8 tube line, is this sleeve the right size or am i off a bit

Answer by: Customer Support on Nov 24, 2025, 2:05 PM

For sizing, it matches a 0.63 inch tube outside diameter, which is the same as a 5/8 inch tube OD.

Question by: Scott S on Nov 27, 2025, 7:09 PM

does this sleeve work with 5/8 inch tube or is that .63 the actual OD measurement?

Answer by: Customer Support on Nov 29, 2025, 1:42 PM

The 0.63 inch figure is the tube outside diameter, which is the standard way to size these fittings. That lines up with what most folks call 5/8 inch tube. So yes, if your tube measures 0.63 inches on the outside, this sleeve is the right fit.

fitting's made of stainless steel right? just want to make sure before I order, been burned before getting regular steel when I needed SS

Answer by: Customer Support on Feb 7, 2026, 5:19 PM

full stainless steel construction on this one. The J10S is an SS sleeve fitting, so you're getting the corrosion resistance that comes with stainless rather than carbon or plated steel. Worth double-checking on any order, so good instinct there.

Question by: Daryl W on Nov 22, 2025, 9:11 PM

got a 5/8 tube, is this the right sleeve for a JIC 37 flare setup?

Answer by: Customer Support on Nov 24, 2025, 6:45 AM

For a 5/8 inch tube OD, this sleeve matches the 0.63 inch tube OD size and it is the female JIC 37 degree flare sleeve style.
