O-Ring 33.7x2.2 NBR

Applications of the 33.7x2.2 NBR O-Ring

Advantages of NBR Material and 70 ShA Hardness

Technical Data and B2B Packaging

Main Description

The O-ring 33.7x2.2 NBR 70 ShA is a precision rubber sealing ring designed for reliable technical sealing in industrial, maintenance, and production applications. Supplied in packs of 100 pieces, it is a practical and cost-effective solution for B2B customers, workshops, and maintenance departments requiring consistent availability of standard sealing components.

Manufactured from NBR (nitrile butadiene rubber), this O-ring offers excellent resistance to oils and grease, mineral oils, fuels, and oil-based emulsions. Thanks to these properties, it is widely used in seals for hydraulics and pneumatics, as well as in general industrial machinery where contact with lubricants is common. NBR is known for good elasticity, abrasion resistance, and dimensional stability, ensuring long service life in demanding environments.

The standard 70 ShA hardness represents the most commonly used compromise between flexibility and mechanical strength. This hardness level allows the O-ring to adapt to minor surface irregularities, providing effective sealing in static sealing applications and in simple dynamic applications with limited movement. The 33.7x2.2 size is frequently used in connectors, housings, grooves, manifolds, and machine components across various industrial sectors.

Typical English search terms related to this product include O-ring 33.7x2.2, NBR O-ring 70 ShA, rubber sealing ring, O-ring for hydraulics, and O-ring for pneumatic systems, confirming its broad industrial relevance.

The bulk packaging of 100 pieces simplifies logistics, storage, and service planning, helping to minimize downtime caused by missing sealing elements.
