Straight Stop Valve - Pex/Male

Flair-It fittings are the answer to mobile home plumbing issues. They last forever, can be hand tightened and work on PEX and Polybutylene (that gray stuff).

This is the fitting you want to use in tight spaces. No need to bend or crease your water lines to line up with a new faucet. Just screw in a flexible hose on the other end of this and finish the job!
