Product Specification

-
Ordered as H3X112, this is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 112 mm (4.409 in), a cross section of 3 mm (0.118 in), and an outside diameter of 118 mm (4.65 in). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is known for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. This material stands up to petroleum-based oils, propane and butane, and greases and lubricants. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where strong acids or polar solvents are present.

Typical settings include hydraulic and pneumatic systems, automotive, and general industrial maintenance.

H3X112 ships individually. Unit weight is approximately 3.2 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
