NBR O-Ring 25x2.5 90 ShA

NBR O-Ring with Increased Hardness for Industrial Applications

Reliable Static and Semi-Dynamic Sealing

Rubber Seal for Hydraulics and Pneumatics

Main Description

NBR O-Ring 25x2.5 90 ShA is a professional technical sealing ring made of nitrile rubber with increased hardness, designed for demanding industrial applications where durability and pressure resistance are essential. The size 25x2.5 defines an inner diameter of 25 mm and a cross-section of 2.5 mm, making this O-ring a common choice for hydraulic, pneumatic, and mechanical sealing systems.

The NBR material offers high resistance to mineral oils, lubricants, fuels, and petroleum-based media. With a hardness of 90 ShA, this O-ring provides enhanced resistance to deformation and extrusion, especially in applications with higher operating pressures. It performs reliably as a rubber seal in precisely machined grooves and housings.

This O-ring is suitable for static sealing and light semi-dynamic applications, ensuring tightness, reducing leakage, and maintaining system pressure. Its dimensional stability and abrasion resistance contribute to longer service life and reduced maintenance costs in industrial environments.

The product is supplied in packs of 100 pieces, which is a practical solution for B2B customers, technical wholesalers, maintenance departments, and production facilities that require consistent quality and efficient stock management.

NBR O-Ring 25x2.5 90 ShA supports reliable operation of sealing systems in machinery, hydraulic units, pneumatic equipment, and industrial assemblies where oil resistance and mechanical strength are critical.
