O-Ring 88x4 NBR

Technical Overview & Material Properties

The O-Ring 88x4 NBR 70 Shore is a precision-engineered sealing component designed for industrial use. It features an inner diameter of 88 mm and a cross-section of 4 mm, made from nitrile rubber (NBR) with a hardness of 70 Shore A. This material delivers excellent resistance to mineral oils, hydraulic fluids and greases, making it especially effective as a rubber gasket or sealing ring in demanding environments. It is suitable for static sealing and light dynamic applications in hydraulics, pneumatics and industrial equipment. The 70 Shore A hardness strikes the ideal balance between flexibility and mechanical durability.

FAQ

Q1: What does the designation “88x4 NBR 70 Shore” indicate?
A1: It designates an O-Ring with an inner diameter of 88 mm, a cross-section of 4 mm, made from nitrile rubber (NBR) with a hardness rating of 70 Shore A. These parameters are critical for correct dimension fitting and sealing performance.

Q2: Is this O-Ring suitable for hydraulic and pneumatic systems?
A2: Yes. The NBR material ensures strong resistance to mineral oils, hydraulic fluids and greases, making it suitable for many industrial hydraulic and pneumatic applications. You should verify compatibility with your specific fluids and conditions.

Q3: What temperature range does this seal support?
A3: Under standard industrial conditions, the typical operating range is approx. - 30 °C to + 110 °C. For higher temperatures or more demanding media, a specialised or upgraded material may be required.

Q4: Can this O-Ring be used in dynamic applications with motion?
A4: This sealing ring is intended for static sealing or lightly dynamic use (minor movement, lower speed). For heavy dynamic motion, large displacement or high speed, a specialist dynamic seal or alternative material would be advised.

Q5: What is the availability and delivery schedule?
A5: The product is stored and dispatched from our warehouse in Lublin at ul. Smoluchowskiego 1, building 4. Delivery is available within 24 hours, helping you maintain seamless supply and avoid downtime.
