Compression fittings interchangeable? (Flexi vs rigid)

[TuKr]

I was wondering if I could use the compression fittings that I purchased for my flexible tubing with rigid tubing the same id, od size? I haven't seen really anything about interchangeability between tubing types.

no, from what i know, they need special rigid tubing compression fittings.
and seems that there is enough variance from one brand to the next that you should buy the same brand of fittings as the brand of tubing.

you should buy the same brand of fittings as the brand of tubing.

This +1

No, flex tubing compression fittings won't work with hard tubing. You might be able to get a conversion kit, though. Here's one for Monsoon fittings.

But as the others said, be careful using fittings from one brand with tubing from another. I think most of the problems have been 12 mm != 1/2 inch, and Monsoon's glue on collars are pretty dodgy even with their own tubing. But I doubt the manufacturers do thorough testing with their competitor's tubing, so it's probably not worth the risk to mix.
