Question by: Wade W on Jan 2, 2026, 3:24 PM

trying to replace an o-ring on an SAE o-ring boss straight thread fitting, is this the right size for a 5/8 tube?

Answer by: Customer Support on Jan 4, 2026, 6:38 AM

For a 0.625 inch tube size, this O-ring matches that tube callout and it’s listed for SAE O-ring boss (straight thread) fittings and adapters. The actual ring dimensions are 0.755 inch ID, 0.949 inch OD, with a 0.097 inch width.

Question by: Larry H on Jun 17, 2025, 8:03 PM

what's the temp range on this o-ring? got a application that sees some heat and want to make sure it'll hold up

Answer by: Customer Support on Jun 19, 2025, 7:49 AM

Buna-N at 90 durometer handles anywhere from -30 up to 250 degrees Fahrenheit, so it's got a solid working range for most hydraulic setups running elevated temps. As long as your system stays within that window, the material holds its shape and sealing properties without breaking down.

Question by: Sherry A on Sep 5, 2025, 8:26 PM

Will this o-ring work with a standard SAE fitting?

Answer by: Customer Support on Sep 7, 2025, 6:05 AM

This O-ring is specifically made for SAE O-ring boss fittings and adapters, so it should be a good fit.
