Looking for the dash number for this oring on perlick 425s. Number 7 in the pic.

I used a -018 (McMaster #1182N018) BUT this was for a 525ss faucet. Can't imagine it's too different, it's just sealing against the shank, right?

What's #'s 8 & 9 for? That's not on the 525's or 630's.

Don't have an old one you could try and measure?

8 and 9 are the slide in 425s and ventamatics. I have some 525s too will compare the size to my 425s, but they should be the same. If not, will break out my caliper. Thanks!
