Cracked fitting to shower faucet - Need Help
Tried to swap out a shower faucet and ran into a problem. The new stems that the water supply attachs to were longer than the original. When I tried to attach the supply line to the faucet stem, I was apparently not lined up perfect and actually stripped the threads on the left stem. Plus, it looked like the plastic fitting (see arrow on picture) cracked so I had a leak when I turned on the water. A bit of a panic since this thing has no shut offs, so if you have a leak, you have to shut off the water to the whole RV. I managed to get the old faucet back on and right now it doesn't leak, but I will eventually need to change the faucet and that one supply fitting.
RVs have what I believe is called PEX tubing for the water supply. Is this what I have according to the picture?
Any suggestions on what I should use to fix this thing?
(I am hoping the image I attached is actually attached). Thanks in advance.
