 Shark bite fittings and Pex
Author: Pneuma (WA)

Hello Everyone,
I have used shark bites since they first arrived on the scene.. on occasion the plastic sleeve that is on both ends of the shark bite doesnt want to go into pex pipe... which made me wonder if they can be used without the sleeve... anyone have experience doing this? I know its to help brace the pipe & im sure the makers would suggest it be there. I would be hesitant to use it w/out even if it sealed.

Thanks!

It always best to use the reinforcing sleeve with pex. Sometimes my pex tube cutter will make the pex end slightly out of round, and I use pliers to gently squeeze the O.D. of the tube back into a round profile. Doesn't take much.. a little dab will do it.

You actually had some blow off a pipe... what kind of pipe did it blow off from and how long did that take to blow off from the installation? I always like to mark the pipe then once i push it on I pull back to be sure its locked in place.

'locked in place' on a plastic tube ?

sounds just like jumbo shrimp or military intelligence

Actually, the teeth will have a better grip on a soft plastic tube, than on hard, smooth copper.

but the plastic can 'give' and 'erode' due to vibration .... stop your arguing

we both know that unless a cross linked polyetheline plastic tube system (a/k/a PEX) is installed as a 'manifolded' home run type it is second class junk

add 'friction clip' fittings and you get ..... ?

And why does installing it that way make it first class junk?

a pressurized tube with 'clamp type' fittings behind closed/completed walls ?

first class / second class junk is still junk

the (assuming unkinked) PEX tube would be acceptable as 'piping', but add 'clamps' ?

shall we stop nit picking? unless we actually have lice!
