Product Specification

-
Part number H50330 is an AS568-330 black Buna-N (Nitrile) 50 Shore A O-Ring built to an inside diameter of 2.1 in (53.34 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.52 in (64.01 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) is widely chosen for low compression set under sustained load and the most widely specified general-purpose sealing elastomer. The compound resists petroleum-based oils, hydraulic fluids, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Applications involving automotive brake fluid or strong acids call for a different compound.

Typical settings include fluid power, general industrial maintenance, and automotive.

Order part number H50330, sold individually. Unit weight is approximately 0.0054 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
