Rubber O Ring BS265 Nitrile 70 Size 196.44x3.53mm

Maintaining a tight, dependable seal is crucial for protecting machinery, preventing fluid loss, and avoiding costly operational downtime. The BS265 Nitrile 70 Rubber O-Ring offers a dependable sealing solution designed specifically for equipment requiring a 196.44mm inner diameter and a 3.53mm cross-section. Built to standard British Standard dimensions, this O-ring integrates seamlessly into existing gland designs across automotive, hydraulic, pneumatic, and general industrial hardware.

Fabricated from standard 70 Durometer Nitrile rubber this O-ring provides superior mechanical performance under varied operating conditions. Nitrile is widely recognized as the workhorse elastomer of the fluid power and industrial seal sectors due to its strong resistance to petroleum oils, mineral lubricants, hydraulic fluids, and water. Its 70 text Shore A durometer rating ensures the material maintains sufficient resilience to conform to housing mating surfaces while remaining rigid enough to resist extrusion under system pressure.

Whether utilized in static sealing arrangements such as flange connections, valve bodies, and pump housings, or in moderate dynamic applications where mechanical movement occurs, the BS265 Nitrile O-Ring delivers dependable service. The elasticity of the NBR compound allows for straightforward installation without permanent deformation, ensuring the seal retains its original cross-sectional profile during routine maintenance cycles.

Using appropriately rated Nitrile seals prevents fluid degradation and seal swelling that often occur when incorrect materials come into contact with oils and hydrocarbons. By reducing friction and resisting tear and abrasion, the BS265 seal helps extend the service life of surrounding components, lower overall maintenance overhead, and keep fluid power systems operating at peak performance. When exact sizing, consistent material quality, and high fluid resistance are mandatory, the BS265 Nitrile 70 O-Ring provides an effective, industry-proven sealing choice.
