Question by: Daryl S on Mar 6, 2026, 12:46 PM

what's the o-ring made of on this fitting, and will it hold up decent against oils and hydraulic fluid?

Answer by: Customer Support on Mar 8, 2026, 9:12 AM

NBR, which stands for Nitrile Butadiene Rubber, is the seal material used here. That's a solid choice for hydraulic fluid and oil service. It handles those environments well and gives you reliable sealing without breaking down quickly under normal use.

Will this swivel fitting hold up to regular use in a hydraulic system, or is it more for light duty stuff?

Answer by: Customer Support on Dec 9, 2025, 6:21 AM

This fitting is made from straight steel and uses a NBR O-ring seal. That should provide good durability and chemical resistance for typical industrial hydraulic applications.
