Product Specification

-
Ordered as H90M5X105, this is a black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 105 mm (4.134 in), a cross section of 5 mm (0.197 in), and an outside diameter of 115 mm (4.53 in). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Expect good resistance to petroleum-based oils, greases and lubricants, and many alcohols. Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, low compression set under sustained load. 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 ketones or automotive brake fluid are present.

Typical settings include general industrial maintenance, construction equipment, and agricultural equipment.

H90M5X105 ships individually. Unit weight is approximately 8.762 g. Review your operating media and conditions against this specification before installation.
