Pex repair fittings
I have a 2005 Komfort 5th wheel and need to replace the kitchen faucet. Is the red and blue pex tubing in the trailer the same size as standard pex. The new faucet has 3/8 compression inlet tubing ...

Pex comes in 100 psi rating and 160 psi rating and is printed on the exterior. The red and blue PEX that an RV manufacturer uses is 100 psi and PEX in a house is 160 psi, but there is 160 psi red & blue PEX. I bought some red & blue PEX at an RV dealer that was 160 psi.
The 100 psi PEX has a slightly smaller diameter. I am not comfortable using a sharkbite because of this but many use sharkbite (or equiv.) fittings with no issues. I always use copper crimp rings but I have a crimper (bought on ebay for cheap years ago). It's very important to make sure the PEX cuts are clean/square.
FWIW, Five different ways to connect PEX
When buying PEX, try and get it in straight lengths. The coiled stuff is a PITA to use in an RV because it has a memory and will not stay straightened no matter how hard you try.
