I'm using a Watts (Lowes) compression fitting with vinyl tubing but I can't get it to stay in the fitting itself. Do I need to change the compression nut or something?

I had compression fittings on the end of my IC with vynil tubing in it. I had to crank those suckers down HARD to get the tubing to stay. then, after using it once, the vynil got soft and would slip righ tout.
I evneually got slightly larger tubing (had some left over form something) and hose clamped it straight onto the copper. This worked so much better.

Agree with all posts. Barb and clamps for flexible/crushable tubing.
You can get away with it if you use a internal support sleeve and a softer ferrule material like nylon, but there's really no benefit to using a compression fitting for soft tubing.

Thanks for all the responses. I'll just pick some barbed fittings instead, thanks.
