Is the O-ring Seal NBR90 Rubber Gasket compatible with common hydraulic oils and fuels used in automotive and industrial systems?

Yes. The O-ring Seal NBR90 Rubber Gasket is compatible with common hydraulic oils and most automotive fuels. Made from premium nitrile (NBR) with 90 Shore A hardness, it offers excellent resistance to oils, fuels and many industrial fluids, making it suitable for hydraulic systems, automotive components and related industrial applications. Its robust composition also provides good durability under pressure, abrasion and wear, helping prevent leaks and maintain system efficiency. Note: While broadly compatible, verify compatibility with specific fluids (e.g., certain hydraulic fluids with additives, aggressive synthetic oils, high-aromatic fuels or specialized solvents) and operating temperatures/pressures before critical use.

Can the O-ring Seal NBR90 Rubber Gasket be used at elevated temperatures or in high-pressure hydraulic systems without losing sealing performance?

The O-ring Seal NBR90 Rubber Gasket offers strong resistance to oils, fuels and many industrial fluids and is engineered for pressure, abrasion and wear, making it suitable for many hydraulic and pneumatic applications. However, its performance at elevated temperatures and in high-pressure hydraulic systems depends on limits typical for NBR (nitrile) with 90 Shore A hardness: - Temperature: NBR90 commonly performs well in typical ambient to moderately elevated temperatures (roughly -30°C to +100°C). Above ~100°C continuous exposure will accelerate aging, hardening and loss of elasticity, reducing sealing effectiveness. - High-pressure hydraulics: The material and hardness provide excellent resistance to extrusion and compression set under moderate to high pressures, so it can work in many hydraulic systems if proper O-ring cross-section, gland design and backup rings are used. Without correct design or at extreme pressures, the risk of extrusion, permanent deformation or leakage increases. Conclusion: The O-ring Seal NBR90 Rubber Gasket can be used in many elevated-temperature and high-pressure hydraulic applications, but only within NBR typical temperature limits (~-30°C to +100°C) and with correct installation/gland design and pressure mitigation (e.g., backup rings). For continuous use above those temperatures or in very high-pressure/extreme-service conditions, select a specialized compound (e.g., FKM, HNBR) or consult technical data and application testing to ensure reliable sealing.
