Product Questions & Answers

What's this O-ring made out of, and is it gonna hold up around hydraulic oil?

Question by: Bonnie P on Jan 25, 2026, 3:20 PM

Buna-N is the material here, which is about as well-suited for hydraulic oil exposure as anything you'll find in this category. It resists petroleum-based oils and fuels, so contact with hydraulic fluid won't cause the kind of swelling or breakdown you'd get with a lesser compound. For standard hydraulic system use, it holds up well under the kind of conditions these systems put a seal through day in and day out.

Can this O-ring handle hydraulic fluid without breaking down?

Buna-N, the material used in this O-ring, is known for its good resistance to oils and fuels, so it should hold up well in hydraulic systems.
