1/2" ID x 5/8" OD Heavy Duty Braided PVC Tubing Reinforced Hose, Non-Toxic for RV Fresh Water (10 feet)

I used this tubing to replace some flexible tubing in my RV. It fits snug on 1/2" fittings. I have not used it much but it seems to be OK so far. I hope it will not expand out with use.

Was a good fit for the necessary repair I had to make on our rv. Wasn't able to locate it locally.

Just what is needed to make the turn from tank to water pump. Allows much more flex than that clear tubing.

Good hose used for camper van project. Added external water fill to our Revel and this was perfect to get it done.

Used to reroute water line from pump in RV. Seems a bit stiff but a little heat from heat gun fixed that.

Hose is flexible but crimps securely with regular Pex barb fittings and rings. Worked to build a new camper shell kitchen and spray hookup.

The ID is not even close to half inch. I bought it for emergency repairs, so I guess I'll keep it. The next time I'll buy from a local RV supply store. I think you'd have to heat it to stretch it on to a fitting, not sure how long it would last stretching it that far. It is thinner walled also.

I am a former contractor, I have run literally miles of plumbing in my day. Nylon, copper, pex, you name it. This stuff is junk, it does not matter how you connect it it leaks. Rv fittings leak, hose barbs leak even if using high doller high pressure clamps, shark bites seem to wor, but the seal to the outside of the hose not the inside, it is not the fittings it is the hose. I bought similar hose from rec pro for the hot water side and it is not having any issues using the same connections.
