Product Specification

-
Part number H70463 is an AS568-463 black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 16.955 in (430.66 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 17.505 in (444.63 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, strong abrasion and tear resistance. Expect good resistance to petroleum-based oils, water, and hydraulic fluids. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving ozone and direct sunlight or ketones call for a different compound.

Typical settings include hydraulic and pneumatic systems, agricultural equipment, and automotive.

H70463 ships individually. Unit weight is approximately 65.173 g and nominal inside diameter is listed as 17 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
