Ordered as H90280, this is an AS568-280 black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 13.984 in (355.19 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 14.262 in (362.25 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Buna-N (Nitrile) is known for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. It resists greases and lubricants, hydraulic fluids, and many alcohols. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ketones or polar solvents are present.

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

Stocked as H90280 and sold individually. Unit weight is approximately 15.334 g and nominal inside diameter is listed as 14 inch.
