Product Specification

-
The H90M3.1X94.4 is a black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 94.4 mm (3.717 in), a cross section of 3.1 mm (0.122 in), and an outside diameter of 100.6 mm (3.96 in). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. Source specification: Metric O-RING, JIS G95.

Buna-N (Nitrile) offers reliable performance in both static and dynamic service, low compression set under sustained load. It resists hydraulic fluids, many alcohols, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where automotive brake fluid or ketones are present.

Common environments for this compound include construction equipment, automotive, and hydraulic and pneumatic systems.
