O-Ring 46 x 3 mm NBR 70 ShA

Applications

The O-Ring 46 x 3 mm NBR 70 ShA is a precision sealing ring designed for industrial-strength applications in hydraulic, pneumatic and general engineering systems. Made from nitrile rubber (NBR) with a Shore A hardness of 70, this rubber gasket offers excellent resilience in demanding environments. It is ideal for static seals, moderate dynamic sealing tasks and installations where oil, lubricant or fuel exposure is expected. Common use-cases include hydraulic cylinders, valve housings, gearboxes, pumps, instrumentation and maintenance kits.

Advantages

• High chemical and oil resistance - NBR material combined with 70 ShA hardness ensures robust performance against mineral oils, greases, fuels and typical industrial fluids.

• Precise dimensional profile - 46 mm inner diameter x 3 mm cross-section provides a reliable seal in standard glands and grooves, reducing leak risk and increasing operational uptime.

• Versatility in industrial sealing - suitable for both hydraulic and pneumatic systems, and for both OEM and service-maintenance environments.

• Bulk packaging efficiency - supplied in a pack of 100 units, enabling streamlined procurement, inventory optimisation and reduced downtime for service departments and production facilities.

• Rapid fulfilment - product stocked in Lublin warehouse (ul. Smoluchowskiego 1, building 4) with 24-hour dispatch supporting fast turnaround.

FAQ

1. What is NBR 70 ShA?
   NBR (nitrile rubber) at 70 Shore A is a compound offering a balance between flexibility and resilience. It is widely used in industrial sealing for its oil and fuel resistance.

2. What size is the O-Ring?
   This model has an inner diameter of 46 mm and a rubber cross-section of 3 mm.

3. Is this O-Ring suitable for hydraulic applications?
   Yes — the NBR material and geometry make it well suited for hydraulic sealing tasks, particularly where exposure to mineral oils and lubricants occurs.

4. What temperature range can this gasket handle?
   Typical service range is from approximately -30 °C up to +100 °C under standard conditions. For extreme temperatures or aggressive media, further evaluation is advised.

5. Why purchase in a pack of 100?
   Bulk packaging supports cost-efficient procurement, ensures spare part availability for maintenance operations and reduces logistic overhead for industrial buyers.
