O-Ring 221,92 x 2,62 mm NBR 90 ShA

Applications

This O-Ring 221,92 x 2,62 mm made from nitrile rubber (NBR) with a hardness of 90 ShA is designed for demanding industrial sealing applications. As a precision rubber gasket or sealing ring it excels in static and light dynamic applications within hydraulic and pneumatic systems, pumps, valves, cylinders and heavy-duty manufacturing equipment. The material’s high resistance to oils, greases and hydraulic fluids makes it an excellent choice for industrial sealing in harsh environments. It enables reliable operation in large-diameter gland grooves and custom sealing arrangements where typical smaller O-rings would not suffice. Use this ring as a robust industrial sealing component in applications requiring long service life, high mechanical load resistance and minimal maintenance.

Advantages

• High durability and high hardness (90 ShA) ensure that the O-ring maintains its shape under pressure and thermal cycling, reducing compression set and leakage risks.

• Industrial sealing for hydraulics & pneumatics: The NBR compound is optimized for oil-based systems and many common lubricants, making it perfect for hydraulic and pneumatic applications with high demands.

• Custom dimension (221.92 x 2.62 mm) means you can deploy it where metric sizes diverge from standard AS568 sizes—ideal for bespoke machine builds or retrofit work.

• Technical sealing ring application: This is not merely a generic “seal”—it is a purpose-built sealing ring for heavy-duty industrial use, offering improved reliability and lower downtime.

• Fast local availability: Warehouse & Store in Lublin at ul. Smoluchowskiego 1, building 4. 🚚 24h delivery ensures that your production or service line can maintain uptime and get rapid access to critical supplies.

FAQ

Q1: What does “90 ShA” mean in the context of this O-Ring?
A: “90 Shore A” indicates the hardness of the rubber compound. A higher number means a firmer material. In this case, 90 ShA ensures the O-Ring resists deformation under pressure, which is critical for demanding industrial sealing tasks.

Q2: Why choose NBR material for this O-Ring instead of another elastomer?
A: NBR (nitrile rubber) is widely used for rubber gaskets and sealing rings in hydraulic & pneumatic systems because of its excellent resistance to oil, grease and fuel contact. It offers cost-effective durability for many industrial media.

Q3: Can this O-Ring be used in dynamic applications (moving parts)?
A: Yes, but primarily in light dynamic or static applications. Given the size (221.92 x 2.62 mm) and hardness, it is optimized for static or limited movement. For high-speed rotary or heavy dynamic loads, a specialized elastomer or backup ring may be warranted.

Q4: How do I ensure the correct fit for this O-Ring in my system?
A: Verify the groove or gland internal diameter matches the O-Ring ID (221.92 mm) and check that the cross-section (2.62 mm) is compatible with the gap or mating part. Ensure sufficient compression, correct media compatibility and operating temperature. For heavy loads or unique conditions, evaluate sealing design guidelines.

Q5: Is 24 h delivery guaranteed for this product?
A: Yes, for stock-listed orders placed via our warehouse in Lublin (ul. Smoluchowskiego 1, building 4) dispatch can be arranged for next-business-day shipping to support industrial service levels.
