Product Specification

-
Ordered as H4X46, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 46 mm (1.811 in), a cross section of 4 mm (0.157 in), and an outside diameter of 54 mm (2.13 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Buna-N (Nitrile) is specified here for low compression set under sustained load, reliable performance in both static and dynamic service. It resists hydraulic fluids, petroleum-based oils, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to ketones or polar solvents will shorten service life.

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

H4X46 ships individually. Unit weight is approximately 2.41 g. Check the compound against your process media, pressure and temperature before committing to a design.
