Product Specification

-
The H70MD103 is an AS568-103 black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 0.081 in (2.06 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.287 in (7.29 mm). This o-ring compresses into its gland to block fluid or gas migration across a joint.

Buna-N (Nitrile) is specified here for most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. The compound resists petroleum-based oils, water, and many alcohols. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Verify compatibility before use with ketones or polar solvents.

The compound is metal detectable for HACCP and foreign-body control programs. It sees regular use in hydraulic and pneumatic systems, general industrial maintenance, and fluid power.

H70MD103 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
