Product Specification

-
Part number H6X168 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 168 mm (6.614 in), a cross section of 6 mm (0.236 in), and an outside diameter of 180 mm (7.09 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to many alcohols, water, and greases and lubricants. Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ozone and direct sunlight or automotive brake fluid.

Typical settings include automotive, fluid power, and agricultural equipment.

H6X168 ships individually. Unit weight is approximately 18.87 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
