Garbage. What do I have to do to make this seal? It stretches & stays that way!
Everything is the size it should be. But, my 3/4 fittings can pretty well be pushed into the tubing--with these sleeve/rings attached--& without using the expansion tool. I bought the Apollo brand expansion tool that's recommended "for ease of use" on so many videos regarding connectivity longevity. These sleeves do nothing--or extremely little to help the PEX remember it's memory placitity--I've had my fitting duct taped to the tubing for 45 minutes--& I can still pull the fitting out. It's like the manual expansion tool warps the tubing on the first pump. If cold weather conditions effect the elasticity or memory--then notice should be given. I'm certainly not the only person to replace my water supply from the house to the meter, after old pipes were discovered leaking. I'm not the only one who has this happen in fall/winter. Also, Home Depot should have everyone working there knowledgeable & trained in PEX installation --since there are 6+ fitting systems!

    I actually prefer to use these vs the Upnor brand most plumbing pros use. The collar is a little bigger and catches the pipe every time vs slipping over.

      The pex A ring failed
      I don't recommend the apollo pex A rings. It failed.
        Aweful rings
        Used these rings, apollo 90s and apollo type a pex. All but about 3 of the connections instantly leaked and continued to leak without any pressure after water was shut off. Ended up cutting it all back out and running copper.
          These are an improvement over Apollo's previous version of expansion...
          These are an improvement over Apollo's previous version of expansion sleeves. The previous version fit loosely and, in some cases, would allow the expansion sleeve to slip off or prevent it from sitting flush on the end of the PEX-A tubing. Apollo's new version fits snugly and prevents slippage and improper installation. However, they can be pretty tough to get on!
