Product Specification

-
The H1X19 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 19 mm (0.748 in), a cross section of 1 mm (0.039 in), and an outside diameter of 21 mm (0.83 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Buna-N (Nitrile) is specified for low compression set under sustained load, reliable performance in both static and dynamic service. It resists petroleum-based oils, hydraulic fluids, and water. The material carries a published service range of -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.

It sees regular use in general industrial maintenance, hydraulic and pneumatic systems, and agricultural equipment.

Stocked as H1X19 and sold individually. Unit weight is approximately 0.0633 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
