Product Questions & Answers (2)

Question by: Johnny C on Feb 6, 2026, 8:58 PM
got a 1/2 inch tube size ORFS fitting, is this the right o-ring for it?
Answer by: Customer Support on Feb 8, 2026, 8:08 PM
For a 0.5 inch tube size O-Ring Face Seal setup, this matches that size callout and it is a Buna-N o-ring at 90 durometer. The dimensions on it are 0.489 inch ID, 0.629 inch OD, and 0.07 inch width.
Question by: Dale F on Jan 12, 2026, 8:37 AM
what material is this o-ring made from and can it handle hydraulic oil without breaking down
Answer by: Customer Support on Jan 14, 2026, 8:56 AM
Buna-N rubber at 90 durometer hardness is what you're working with here. That compound holds up well against oil, fuel, and the kind of industrial fluids you'd run through a hydraulic system. The 90 durometer rating means it's on the firmer side, which helps it maintain its shape under pressure rather than deforming over time in a face seal application.
