NBR Material Seal Solutions — Bost Engineering Plastics

NBR Material Seal Solutions by Bost

Product Overview

Bost's NBR material seal line delivers engineered sealing solutions designed for demanding industrial, automotive and hydraulic applications. Using nitrile butadiene rubber (NBR), our seals offer excellent resistance to oils, fuels and lubricants while maintaining dimensional stability and long service life. Paired with Bost’s advanced engineering plastics and steel-plastic assemblies, these seals form durable, integrated components for modern equipment.

Key Properties & Performance

NBR material seals from Bost provide balanced performance: superior oil and fuel resistance, good abrasion resistance, low compression set and reliable performance in temperatures typically from -40°C to +120°C. Available in Shore A hardnesses from ~40 to 90, our seals can be tailored for static or dynamic sealing, low-friction sliding, or high-pressure applications. This optimized property set makes Bost NBR seals ideal where long-term reliability is critical.

Manufacturing & Customization

Bost combines deep R&D expertise with precision molding, extrusion and CNC machining to produce custom NBR material seals in a wide range of profiles, sizes and compound formulations. We excel at multi-material solutions—overmolding NBR to engineering plastic housings or bonding seals to steel—enabling integrated parts with enhanced toughness, flame retardancy and thermal conductivity when required.

Applications

Our NBR material seals are widely used in hydraulic systems, pumps, automotive fuel systems, compressors, industrial valves and green energy equipment. Where compatibility with oils, fuels and hydraulic fluids is required alongside high wear resistance and fatigue life, Bost NBR seals deliver reliable sealing performance that reduces downtime and maintenance costs.

Quality, Testing & Sustainability

Bost adheres to strict quality controls and testing standards (ASTM/ISO) throughout compound development and production. As a high-tech green energy engineering plastics manufacturer, we prioritize sustainable processes, low-emission materials and efficient production to support customers’ environmental goals while ensuring exceptional product quality.
