Product Specification

-
Part number H5X155 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 155 mm (6.102 in), a cross section of 5 mm (0.197 in), and an outside diameter of 165 mm (6.5 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

It resists greases and lubricants, propane and butane, and water. That behavior comes from the compound itself: Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer and low compression set under sustained load. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C).

Common environments for this compound include agricultural equipment, general industrial maintenance, and hydraulic and pneumatic systems.

Reference part number H5X155 when ordering; the item is sold individually. Unit weight is approximately 12.235 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
