O-Ring 6x1 NBR

Applications of O-Ring 6x1 NBR 70 ShA

The O-Ring 6x1 NBR 70 ShA is a durable, oil-resistant rubber sealing ring designed for demanding industrial, hydraulic, and pneumatic applications. Manufactured from high-quality NBR (nitrile butadiene rubber), it ensures reliable sealing performance against oils, fuels, lubricants, and other fluids commonly used in mechanical and process systems.

With its 6 mm inner diameter and 1 mm cross-section, this O-ring is ideal for use in static and low-dynamic sealing points such as valves, pumps, cylinders, and fittings. The hardness of 70 Shore A guarantees the right balance between flexibility and mechanical stability, providing long-lasting sealing and dimensional consistency under pressure.

The product is delivered in an industrial bulk pack of 1000 pieces, perfectly suited for maintenance departments, production lines, and distributors serving the B2B sector.

Technical Data

FAQ - Frequently Asked Questions

1. What are NBR O-Rings used for?
They are used for sealing in hydraulic and pneumatic systems, as well as in machinery and industrial equipment exposed to oils, fuels, and lubricants.

2. What is the temperature resistance of NBR 70 ShA O-Rings?
They operate effectively between -30°C and +100°C, which covers most industrial and automotive applications.

3. Can this O-Ring be used for dynamic sealing?
Yes, for low-speed movements or slight shaft oscillations. For continuous high-speed rotation, specialized rotary seals are recommended.

4. What is the difference between NBR and FKM materials?
NBR is ideal for oil and fuel resistance at moderate temperatures, while FKM (Viton®) performs better under high temperatures and aggressive chemicals.

5. Is this O-Ring suitable for bulk or OEM use?
Yes, the 1000-piece industrial pack is designed for professional buyers, production facilities, and maintenance departments.
