3MM CS X 24MM ID BLACK BUNA 90D

Ordered as H90M3X24, this is a black Buna-N (Nitrile) 90 Shore A O-Ring with an inside diameter of 24 mm (0.945 in), a cross section of 3 mm (0.118 in), and an outside diameter of 30 mm (1.18 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

This material stands up to many alcohols, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or strong acids are present.

Maintenance and OEM teams specify it across general industrial maintenance, hydraulic and pneumatic systems, and agricultural equipment.

Reference part number H90M3X24 when ordering; the item is sold individually. Unit weight is approximately 0.79 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
