Product Specification

-
H7X355 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 355 mm (13.976 in), a cross section of 7 mm (0.276 in), and an outside diameter of 369 mm (14.53 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. The material holds up against water, petroleum-based oils, and propane and butane. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or ketones will shorten service life.

It sees regular use in automotive, general industrial maintenance, and agricultural equipment.

Order part number H7X355, sold individually. Unit weight is approximately 54.11 g. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
