Installing Compression Fittings

post #1 of 13
Thread Starter 
So I have a bunch of 1/2" x 3/4" Bitspower compression fittings and I was testing out installing them on my 1/2" x 3/4" Tygon tubing.

I had a very tough time trying to fully screw the compression down fully onto the tubing. Is this normal? Should I be using tools?

you only have to hand tighten them, not all the way down

There will be about a 1/8" gap between the two pieces of the fitting when tightened. like the poster above said tighten them hand tight and be done with it.

If anything, a couple of threads showing. Else, just below the last thread if you want to be conservative.

^That's tighter than you need to go, and here's why: Think about how much force you need to get it that tight. Now recall that you have extra effective leverage because you're screwing it down instead of directly clamping it. That's a lot of clamping force.

Not much force at all, actually. Best invest in a pair of Captains of Crush .

I just lightly hand tighten and I've never had a leak. It's nice to be able to turn the compression to remove it without unscrewing the whole fitting. People definitely over tighten this kind of fitting. With 22 compression fittings I'd think that I'd have had a leak already if I was doing it incorrectly.
