We discovered a 20 + year old water stop valve that was leaking under our bathroom sink. Since trying to find a universal valve repair kit is quite difficult, we opted to replace the leaking supply valve.
We used a Watts Aqualock push fit valve to speed the repair. Check Amazon for that and similar water stop supply valves:

Watts AquaLock (3539-10)- Large Diameter Stop Valve/Shut Off Valve- 1/2" CTS/Single

Watts
959098 Aqualock 3539-10 (P-650) Straight Valve, 1/2"

A similar product is made by Sharkbite :

SharkBite 1/2 x 3/8 Inch Compression Straight Stop Valve, Quarter Turn, Push to Connect Brass Plumbing Fitting, PEX Pipe, Copper, CPVC, PE-RT, HDPE, 23037-0000LF

The process takes a littletime but is straight forward. Sink water supply shut offs will vary. Ours had a 3/8 inch copper line from the top of the shut off valve to the faucet. At the bottom of the shut off valve, we had a 1 inch copper pipe. Both ends of the existing supply valves were compression fittings.
