28mm PEX outer pipe joint

Joint for 28mm outer pipe on PEX (pipe in pipe) system. I had to improvise and make this since excisting outer pipe was to short before entering the coupler cabinet to avoid disconnecting it all. The outer pipe is designed to bring any leakyy water from the inner pipe baco to a safe place (coupler cabinet or drain). The jointer is designed with grooves on the inside for O-rings or for loctite seal paste or similar to make a water tight seal. I did add thin double sided 3M tape on the inside to get it so stict to the pipe, and I also have added grooves for zip ties. To be used on your own risk.
