Compression Fittings

[Phobia]

I made an order from sidewinders and it showed up today, but I ordered the wrong size fittings. I accidentally ordered 5/8" OD compression fittings.. Is there any tubing that will fit these?

I ordered these: Bitspower True Silver 1/2in. Compression Fittings for 5/8in. OD Tubing instead of these: Bitspower True Silver 1/2in. Compression Fittings for 3/4in. OD Tubing

My suggestion would be to buy new tubing, easier to replace and much cheaper than the fittings! I don't know if it'll fit or not though.

OOps, thats what i meant my question to be. Will other tubing fit 5/8" OD and 1/2" ID compression fittings? And if so, is there any in Canada?

There's 3/8 and 5/8... but I haven't seen much 1/2ID 5/8OD now that you mention it.

7/16 ID is 5/8 OD and will fir 1/2ID fittings nice and tight.

This. If you're having issues getting the 7/16th on the 'barb', soak it in near-boiling water for 10-15 seconds. She'll go right on after that

Very tight. The tubing wall is thicker than 1/2-5/8 stuff, so you may run into difficulty when it comes time to actually tighten the collar down - the collar winds up pinching above the fitting, instead of around it, which makes for a lousy seal. I've seen one or two threads to that effect, so think carefully.

You can get 1/2-5/8 Tygon although it's almost certain to go cloudy within a month or two, and the thinner walls take a bite out of your bend radius.

Phobes.. suggest you just replace those fittings, otherwise you will be fighting putting the 7/16 tubing on the 1/2" barbs.. And if you do get it on, good luck getting it off..

Thanks guys, and I did indeed order new ones. I don't know what to do with the smaller fittings though. Miggs, I did have 7/16th tubing on 1/2" barbs before, but that wasn't with compression fittings, and I don't want to have an improper seal like MPG said.

No worries, I had it too.. when I was first installing my loop, I fought with it.. Waste of tubing, because (at least for me).. the only way to take the tubing off the barb was the cut it off..

On a side note, I got one Feser 45 degree angled barb, one side is compression, darn it looks sexy :p I might switch..
