Match it up by dash size and IDs. This is a dash -120 Buna-N O-ring with a nominal 1 inch ID and 1-3/16 inch OD, and it also crosses to part number 568-120.

these come in a pack of 50, right? just wanna make sure before i order cause i need a good quantity on hand for our press maintenance

these ship in packs of 50. Good call stocking up if you're doing regular press maintenance. At that quantity you'll have plenty on hand for replacements without having to reorder every time one goes out.

Tell us what you need and we'll get back to you.
