Product Specification

-
APG stocks the H5X185, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 185 mm (7.283 in), a cross section of 5 mm (0.197 in), and an outside diameter of 195 mm (7.68 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Buna-N (Nitrile) is widely chosen for low compression set under sustained load, strong abrasion and tear resistance. The compound resists petroleum-based oils, water, and many alcohols. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in ozone and direct sunlight or automotive brake fluid.

Typical settings include fluid power, construction equipment, and agricultural equipment.
