Buna-N O-Ring Kit by Polypac: Reliable NBR Sealing Solutions

Product Overview

Polypac's Buna-N O-Ring Kit provides a comprehensive selection of NBR (Buna-N) O-rings engineered for oil, fuel and hydraulic applications. Each kit contains commonly used sizes and cross-sections to support assembly, maintenance and field repairs. Designed for professionals, the kits balance immediate availability with the option for rapid customization.

Key Features & Material Benefits

Buna-N (NBR) is prized for excellent resistance to petroleum oils, hydraulic fluids and good wear properties. Typical operating temperatures range from -40°C to +120°C depending on compound. Our Buna-N O-Ring Kit emphasizes tear resistance, compression set control and consistent hardness—critical for long-term sealing performance in dynamic and static joints.

Applications & Compatibility

These kits are ideal for hydraulic systems, automotive fuel systems, industrial pumps, compressors and general-purpose sealing. The Buna-N O-Ring Kit suits environments with oil exposure, moderate heat and mechanical stress. For aggressive chemicals or extreme temperatures, Polypac offers alternative elastomers such as FKM and FFKM.
