Modular home kitchen sink repair

While changing my kitchen faucet I noticed a leak in my fitting on the hot water side.
I would like to replace these lines but have never worked with this type of line or fitting before.
This appears to have a permanent metal clamp holding the fitting, and has the same type of clamp down at the other end, at the valve.
Is there a way I can change this to a more flexible line, or do I need to just replace the fitting?
Any help is greatly appreciated.

Welcome to the forums.

In the picture you are showing us a fitting that is crimped onto the line.
Normally a flex line would have a crimped on fitting at both ends so that it would be removable for replacement.

Do you have a similar fitting on the other end of the hose ?

My line is plastic, and there is a metal ring crimped onto both ends. One end crimped to the fitting that is leaking, the other end is crimped directly to the shut off valve.

I've never seen plastic line crimped right to the shutoff valve.
The shutoff valve is where the copper pipe from the house connects to the valve.

So you're saying the faucet side of the line has the nut..... correct ?

I will double check when I get home, but I am certain it was crimped directly to the valve. I'm pretth sure there was no threaded connector on that end.
I had to use paint, and it's not to scale, but I think this is pretty much what I have:

I'd replace the valve and supply line. Back circa late 70s early 80s they sold supply valves with corrugated metal line integrated into the valves. I'm assuming this is similar. The fix is get rid of the valve and supply line and put in a separate valve and supply line. What is the valve on? Copper tubing? Is it flared?

Edit our posts crossed. I see you have plastic not copper. I wonder if it is pex? Not sure what to advise.

PJ, MHs use a lot of strange fittings/procedures in their plumbing. There probably aren't any copper pipes. Plumbing isn't my strong suit but I'd try to change what I could to a more conventional set up.

Looks like pex. You need a special crimping tool to fox that. If that is all your homes plumbing then its good to own this tool.

0650872 - Watts 0650872 - 3/8" - 3/4" PEX Crimp All Tool Kit

Then some rings. And the proper fittings.


HCRIMP05 - Rifeng HCRIMP05 - 1/2" PEX Crimp Ring


Simple way would be with a shark bite fitting. A coupling and a piece of pex and the proper fitting.

Thanks for the info.
When I got home I got under the sink with a flashlight and could read "PEX" on the plastic tubing.
Now I just need to get a tube cutter, the fittings, and the tool.
I don't know how familiar you might be with these, but there was a different type of crimp tool and ring available, more of a pinch type crimp, and I was wondering if it would be as good?

Get the same ring type that you have. Im not a fan of the cinch rings as you mention. I like and use the crimp rings only...

I found the SharkBite style fittings and they worked.
