O-Ring 95x2.5 NBR 70 ShA

O-Ring 95x2.5 NBR 70 ShA - Reliable Technical Sealing

The O-Ring 95x2.5 NBR 70 ShA is a precision manufactured rubber sealing ring designed for industrial, hydraulic and pneumatic applications. The 95x2.5 dimension refers to an inner diameter of 95 mm and a 2.5 mm cross section, ensuring accurate fit in standard sealing grooves used in housings, covers and mechanical assemblies.

Made from Nitrile Butadiene Rubber NBR with a hardness of 70 ShA, this O-Ring offers high resistance to mineral oils, greases and fuels. The material combines flexibility with mechanical strength, delivering durable static sealing performance and reliable operation under varying loads. NBR 70 ShA is widely specified for industrial sealing due to its balanced elasticity and resistance to wear.

The O-Ring 95x2.5 NBR 70 ShA is typically used as a static seal and can also perform in light dynamic applications where limited movement occurs. It supports leak prevention and pressure retention in systems exposed to lubricants and petroleum based fluids.

Applications in Hydraulic and Industrial Systems

This O-Ring is commonly applied in:

• hydraulic systems

• pneumatic installations

• pumps and valves

• cylinders and actuators

• industrial machine housings

Thanks to the high oil resistance and dimensional stability of NBR 70 ShA, the sealing ring ensures consistent technical sealing in demanding industrial environments.

Technical Properties and Material Performance

The O-Ring 95x2.5 NBR 70 ShA provides:

• high resistance to oils, greases and fuels

• good abrasion resistance

• stable performance under compression

• reliable static sealing capability

The 70 ShA hardness ensures an optimal balance between flexibility and durability, reducing the risk of deformation and premature failure.
