Product Specification

-

An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) delivers strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

Common environments for this compound include automotive, general industrial maintenance, and agricultural equipment.
