Just want to make sure this'll fit my fitting... It's a 1 inch.

Answer by: Customer Support on May 8, 2025, 8:01 AM

This O-ring is specifically sized for SAE O-Ring Boss (Straight Thread O-Ring) fittings and adapters that are 1.00 inch.

Question by: Gene J on Feb 23, 2026, 5:36 PM

what temp range is this o-ring good for? got some fittings running pretty warm and wanna make sure it'll hold up

Answer by: Customer Support on Feb 25, 2026, 6:54 AM

Buna-N at 90 durometer handles a range of -30 to +250 degrees Fahrenheit, so moderate heat from standard hydraulic system operation falls well within that window. As long as your fittings aren't pushing past that upper limit, you're in good shape.
