So this is a standard size O-ring, right? Like one you'd find on most hydraulic fittings?

Typically, folks use this size O-ring (size 211) in hydraulic systems for sealing connections and preventing leaks. The listed dimensions should help you confirm if it's the right fit for your specific application.

what temp range does this o-ring hold up to? got some equipment running pretty hot and need to know before I order a bunch of em

Question by: Dustin S on Mar 24, 2025, 6:21 PM

Buna-N at 70 durometer handles a range of negative 40 degrees F up to 240 degrees F. If your equipment stays under that ceiling, this one should hold up fine for regular use.

Question by: Clint T on Jan 5, 2026, 2:47 PM

It lines up with the A-211 cross reference shown for this part. The nominal size is 13/16 inch ID by 1-1/16 inch OD with a 1/8 inch width, and the listed actual measurements are about 0.80 inch ID, 1.07 inch OD, and 0.14 inch width.
