O-ring 98X4 NBR

Technical Features & Material Specifications

This O-Ring of 98 mm inner diameter x 4 mm cross-section, manufactured from nitrile rubber (NBR) with a hardness rating of 70 Shore A, is engineered for reliable industrial sealing. As a rubber gasket or sealing ring, it supports static and lightly dynamic applications across hydraulic and pneumatic systems. The nitrile rubber compound offers excellent oil- and fluid-resistance, making it an optimal choice for heavy-duty industrial equipment. Materials data denote operating ranges approximately ­-30 °C up to +100 -120 °C, aligned with the NBR 70 Shore classification.

Applications & Benefits for B2B Procurement

FAQ

Q1: What does the specification “98x4 NBR 70 Shore” mean?
A1: It designates an O-Ring with inner diameter 98 mm, cross-section 4 mm, made from nitrile rubber (NBR) with hardness 70 Shore A. These parameters ensure correct physical fit and seal performance.

Q2: Can this O-Ring be used in hydraulic systems?
A2: Yes. The nitrile rubber compound offers excellent resistance to mineral oils, hydraulic fluids and greases, making the O-Ring suitable for many hydraulic and pneumatic applications. However, always verify media compatibility and temperature conditions.

Q3: What temperature range can I expect for this sealing ring?
A3: Under typical industrial conditions, the operating temperature is approximately from -30 °C up to +100-120 °C. For significantly higher temperatures or aggressive media, consider alternative elastomers or specification upgrades.

Q4: Is this product suitable for dynamic motion applications?
A4: The seal is primarily intended for static or lightly dynamic applications (minor movement, moderate speeds). For heavy dynamic motion, oscillation or large displacement, a dedicated dynamic seal or higher-performance material might be preferable.

Q5: What is the availability and delivery timeframe?
A5: This product is stocked in our Lublin warehouse (ul. Smoluchowskiego 1, building 4) and can be dispatched within 24 hours, ensuring rapid replenishment of supplies and minimal downtime for industrial operations.
