Main Description

The O-Ring 110x5.5 NBR is a precision-engineered industrial sealing ring designed for dependable performance in demanding hydraulic and pneumatic applications. With an inner diameter of 110 mm and a 5.5 mm cross-section, this O-Ring offers an increased sealing volume and enhanced compression stability, making it suitable for systems exposed to pressure fluctuations, vibration, and continuous operation.

Manufactured from NBR (nitrile butadiene rubber), this rubber seal provides excellent chemical resistance to mineral oils, lubricants, fuels, and many industrial media. NBR is a widely used elastomer in technical sealing components due to its balanced mechanical strength, elasticity, and resistance to wear. These properties translate into high durability, predictable sealing behavior, and extended service life in industrial environments.

The O-Ring 110x5.5 NBR is commonly applied as a static seal in housings, flanges, covers, and valve bodies, where consistent surface contact and leak prevention are critical. It is also suitable for selected dynamic applications with controlled movement, such as pistons and rotary assemblies, when proper groove design is applied. The optimized geometry ensures uniform load distribution across the sealing surface, reducing the risk of extrusion and premature failure.

This industrial rubber gasket is widely used in machinery, pumps, compressors, hydraulic power units, gearboxes, and general-purpose equipment across manufacturing, maintenance, and OEM sectors. Its standard dimensions allow easy integration into existing designs, supporting efficient installation, fast replacement, and reliable sealing performance.

Designed for professional B2B use, the O-Ring 110x5.5 NBR supports stable system pressure, reduced downtime, and lower maintenance costs, making it a practical choice for industrial buyers and engineers seeking dependable sealing solutions.
