Toy Hauler (work and play 18L) line question

[Brettz]

I have to make a minor repair to my plumbing under my bathroom sink. (coupler, short length of line and an inline shutoff valve) However, before I order the parts, I would love to know what the correct type of line/pipe is in my camper!

Would someone please give me the "technical" name for it? It appears to be approximately 1/2" diameter, but I'd like to know for sure what it is!

Thanks for your help!

It's called PEX ,I think. You can get all fittings,and pipe,or tubing,whichever.ar lowes or depot.

Cross-linked polyethylene, commonly abbreviated PEX or XLPE. Excellent product for plumbing.

Thank you! Is there a standard diameter? 1/2" ID?

PEX comes in many sizes from 1/4 inch to 2 inches. Most common is 1/2 inch for plumbing. What you have is 1/2. Make sure you use fittings designed for PEX. Brass fittings are the preferred fittings and are expensive.
