High temperature NBR O-ring kit

High temperature NBR O-ring kit

Product Overview

Polypac's High temperature NBR O-ring kit is engineered for systems that demand reliable sealing under elevated temperatures and aggressive hydraulic fluids. Each kit contains a carefully selected range of O-ring sizes made from specially formulated high-temperature NBR compounds, providing improved heat resistance while retaining the classic oil and fuel compatibility of nitrile elastomers. The kits are ideal for maintenance teams, OEMs, and field service operations requiring ready access to common sizes and rapid replacement.

Material & Performance

Our high-temperature NBR blends are optimized to operate beyond standard NBR limits, offering extended thermal stability, excellent resistance to mineral oils, hydraulic fluids, and many lubricants, and good mechanical strength. Polypac's R&D collaborates with universities and research institutes to refine compound formulations that minimize compression set and swelling at elevated temperatures, ensuring longer service life and consistent sealing performance in dynamic and static applications.

Applications

The High temperature NBR O-ring kit is designed for hydraulic systems, oil seals, pumps, compressors, automotive engine components, and industrial machinery exposed to higher operating temperatures. Typical uses include mobile hydraulics, industrial presses, and oil-handling equipment where standard NBR would age prematurely. Kits cater to both routine maintenance and critical repair needs, reducing downtime with on-hand, high-quality seals.

Customization & Quality Assurance

Polypac manufactures custom rubber rings and O-rings across a wide range of sizes and tolerances. Our factory spans over 10,000 square meters and uses advanced production and testing equipment to ensure each High temperature NBR O-ring kit meets strict quality criteria. We support bespoke formulations, durometers, and packaging options, and conduct comprehensive testing to validate temperature, compression set, hardness, and fluid compatibility.

Ordering & Support

Ordering is straightforward: choose a standard kit or request a custom solution tailored to your operating conditions. Polypac provides technical consultation, material selection guidance, and fast turnaround. For teams seeking durable, cost-effective high-temperature sealing solutions, our O-ring kits combine material science, manufacturing scale, and field-proven performance.
