Product Specification

-
The H6X12 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 12 mm (0.472 in), a cross section of 6 mm (0.236 in), and an outside diameter of 24 mm (0.94 in). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to petroleum-based oils, many alcohols, and propane and butane. Buna-N (Nitrile) delivers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to automotive brake fluid or ozone and direct sunlight will shorten service life.

Typical settings include agricultural equipment, automotive, and hydraulic and pneumatic systems.

This item is sold individually under part number H6X12. Unit weight is approximately 1.97 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
