Product Specification

-
APG stocks the H4X184, a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 184 mm (7.244 in), a cross section of 4 mm (0.157 in), and an outside diameter of 192 mm (7.56 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to water, propane and butane, and petroleum-based oils. Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, strong abrasion and tear resistance. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to ozone and direct sunlight or automotive brake fluid will shorten service life.

Common environments for this compound include fluid power, construction equipment, and automotive.

Order part number H4X184, sold individually. Unit weight is approximately 9.11 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
