This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A supplied with an inside diameter of 98 mm (3.858 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 105 mm (4.13 in), catalogued under part number H3.5X98. It delivers dependable bidirectional sealing in a compact groove envelope.
The compound resists hydraulic fluids, greases and lubricants, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for low compression set under sustained load, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or strong acids call for a different compound.
You will find this material specified across hydraulic and pneumatic systems, agricultural equipment, and general industrial maintenance.
Order part number H3.5X98, sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
