NBR O-Ring 6mm - 70 Shore A Nitrile Seals

70 Shore A refers to the hardness of the elastomer measured on the Shore A durometer scale. For NBR O-rings, 70 Shore A represents a medium hardness that balances flexibility, compression set resistance, and sealing performance. It is the most commonly specified durometer for general hydraulic, pneumatic, and industrial sealing applications.

NBR (Nitrile Butadiene Rubber) is a synthetic rubber known for excellent resistance to petroleum-based oils, fuels, and hydraulic fluids. It performs well in temperature ranges from approximately -26°C to 125°C. NBR is widely used in automotive, hydraulic, and industrial applications where oil and fuel exposure is common.

Detroit Sealing Components supplies 6mm NBR O-rings across multiple international size standards including AS568 (American), Metric, JIS B2401 (Japanese), BS 4518 (British), and others. This ensures compatibility with equipment designed to any major global standard, supported by a comprehensive size range from 0.5mm ID up to 1600mm ID.

Yes. DSC's Infinite Size O-Ring product uses continuous molding technology to produce seals with unlimited inner diameters and cross-sections from 3mm to 25mm, all without costly tooling. This makes it ideal for large-scale, custom, or low-volume requirements where standard mold sizes are unavailable or uneconomical.

Yes. DSC offers comprehensive O-Ring Kits containing assorted sizes in NBR 70 and 90 durometer compounds, organized in color-coded packaging for easy inventory management. Kits cover AS568, JIS B2401, and Metric standards and are suitable for general industrial maintenance, plumbing, hydraulic system repair, and seal replacement operations.

6mm NBR O-rings at 70 Shore A hardness are used across a broad range of industries including automotive, oil and gas, hydraulic and pneumatic systems, food and beverage, agriculture, construction, healthcare, aerospace, and general industrial manufacturing. Their oil and fuel resistance makes them especially prevalent in fluid power and mechanical sealing applications.
