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.

If it dosen't leak now, the nut is probably not cracked. But if you stripped the thread on the new faucet, you will need a new faucet. The material is not PEX, but simalar. Pex makes a fitting that will attach without speacial tools. Any mobil home supply co., or lumber yard should have it.

Looks like a standard pex fitting sold at Lowe's. However you would need a crimper to replace it. You can change to a Shark bite fitting that they sell also. no crimp tool needed to install. I've used them several times and never had a leak with them.

Sharkbite's are building code acceptable. Have used several in both S&B homes and RV over the last 2-3 years without a problem to date. They also have a steel mesh covered hose with sharkbites installed on both ends to allow connecting in tight spots. Just used a pair of the hoses to install a new faucet in a S&B shower last month Just besure to fully seat the tubing/plex all the way into the sharkbite and give it a small twist to help seat it tightly
