I have been beating my head against the wall for three weeks

>Everyone tells me the half inch supply hose should fit right onto the half inch compression line but it doesn't..

3/8 compression fitting on the shutoff valve end?

might be a good time to think about replacing it

I had a similar problem. I had 1/2" black pipe which the of is 5/8" and the only thing I found to fit it was a valve with a few adapters. That thing leaked llike the titanic

I'm pretty positive that it is half inch. If I take the old line that was attached to the valve it will fit onto a half inch male connector but the half inch hose will not attach the valve.

Picture of the old compression line.

Like I said I had the same problem when I replaced the toilet. No one could help me until I went to Law Brothers (RIP) and that guy found me a part in like ten seconds that got it working right away.

I have to replace those poly pipes but I'm not looking forward to ripping out the walls to get to them.

go to a mobile home supply house
they use those type of plastic fittings

How about changing the valve itself, and buy the supply line that works with the new valve? If the problem is the old plumbing, maybe invest in switching to PEX. That should be fairly cheap and easy compared to changing the pipes to copper, in your situation.

isThis might get you into the right ballpark

I am going to have to rip out the walls to get to those pipes.

All I wanted to do was put in a new sink and faucet and now...

the hell? you should be able to replace the valve regardless. your time wasting isn't due to lack of parts but complete ignorance.

you do have a valve on the wall like in the pic right? It's not just a pipe without a cutoff, right?

And you're not trying to remove the valve are you?

Also, sharkbite makes polybutylene to CTS (copper, cpvc, pex, etc sizing) adapters
Take the old supply to a homedepot type place or plumbing/ hardware store.
Figure out what size and kind of threads they are.

Pretty damn sure they will be 3/8 compression threads

And if your new faucet came with only copper tubes sticking out, just put a metal compression union on there to connect to a supply line.

You can also sweat a male adapter on the faucet supply once you know what kind of flexible supply you can use.

I get the feeling you're doing something wierd like mixing up pipe threads vs compression threads

Are you mixing up the ends?
Faucet side threads are usually pipe thread size, where the valve end is usually compression sized

although PB installs in trailers for instance sometimes did mix thread types and sizes in odd combinations for god knows what reason.

I've read this thread several times.
I'm pretty sure you can't sweat a copper line.

Most of us say sweating meaning soldering.
What do you think it means?

And if you don't solder copper and brass fittings, what do you solder? PVC CPVC PEX etc? all those will melt if you take a torch to them.
Threaded steel? There were a very limited number of fittings that came with a hole on the female side for you to introduce solder into the threaded joint.

I think it means soldering
With a torch and solder and flux
I stand by my assertion that OP can't solder copper tubing.
