1.6MM CS X 27.1MM ID BLACK BUNA 90D

Ordered as H90M1.6X27.1, this is a black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 27.1 mm (1.067 in), a cross section of 1.6 mm (0.063 in), and an outside diameter of 30.3 mm (1.19 in). The o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists propane and butane, greases and lubricants, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in strong acids or ozone and direct sunlight.

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

H90M1.6X27.1 ships individually. Review your operating media and conditions against this specification before installation.
