2.4MM CS X 10.8MM ID BLACK BUNA 90D

H90M2.4X10.8 is a black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 10.8 mm (0.425 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 15.6 mm (0.61 in). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies. Supplementary detail from the product record: Metric O-RING, JIS P11.

This material stands up to greases and lubricants, petroleum-based oils, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or ozone and direct sunlight will shorten service life.

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

H90M2.4X10.8 ships individually. Unit weight is approximately 0.264 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
