Part number H5.7X49.2 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 49.2 mm (1.937 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 60.6 mm (2.39 in). An o-ring compresses into its gland to block fluid or gas migration across a joint.
As a material, Buna-N (Nitrile) is specified for strong abrasion and tear resistance, low compression set under sustained load. It resists water, greases and lubricants, and many alcohols. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C).
Common environments for this compound include agricultural equipment, fluid power, and construction equipment.
H5.7X49.2 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
