Help identifying a supply shut off valve

[solidcell]

I was shutting off the water supply via the shut-off valves shown (circled in red) in order to replace the shower valve cartridge. However, they're in pretty bad shape and leaking a bit as I was turning them to the off position. I need to find replacement stems for them, but I'm not sure how to find what I'm looking for. Searching on Amazon and Lowes is just turning up a bunch of shower cartridges. I went by my local plumbing supply and the clerk had no idea what this is. It seems like this should be pretty simple, but maybe not?

Any advice would be appreciated!

Those are old style Delta Integral stop valves.

I’ll look the model number up for you.

It takes the same washer and packing gland as a Brasscraft multi turn stop. You could go to Home Depot or Lowes and buy a Brasscraft multi turn stop and rob the rubber parts out and use them for replacements if you’re in a hurry….or it might be cheaper that way.

Delta RP16213 is what you need.
