The H90035 is an AS568-035 black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 2.239 in (56.87 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.379 in (60.43 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. It resists propane and butane, petroleum-based oils, and many alcohols. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ketones or automotive brake fluid will shorten service life.
You will find this material specified across general industrial maintenance, construction equipment, and agricultural equipment.
Order part number H90035, sold individually. Unit weight is approximately 0.658 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
