Buna-N O-Ring Kits — Reliable Sealing from Polypac

Product Overview

Polypac's Buna-N O-Ring Kits are engineered for dependable sealing in hydraulic, pneumatic and industrial applications. Formulated from High Quality NBR (Buna-N), these kits combine oil, fuel and hydraulic fluid resistance with excellent mechanical strength. Each kit includes a range of cross-sections and diameters for maintenance, prototyping and on-site repair, making them an essential maintenance item for service teams and OEMs.

Materials & Performance

Buna-N (NBR) delivers balanced performance across temperature and chemical environments: typical operating range -40°C to +120°C, strong resistance to mineral oils, greases and many hydraulic fluids, and good abrasion and compression set properties. Polypac tailors hardness, tolerances and compound formulations to meet specific pressure and dynamic sealing requirements, ensuring optimal longevity and leak prevention for rotating, reciprocating and static interfaces.

Applications & Industries

Our Buna-N O-Ring Kits are widely used in hydraulic cylinders, pumps, valves, compressors, automotive assemblies and industrial equipment. Customers across construction, agricultural machinery, oil & gas, and manufacturing rely on Polypac kits for fast repairs, scheduled maintenance and OEM supply. Kits are organized for quick identification and field deployment that minimize downtime.
