Part number H5X92 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 92 mm (3.622 in), a cross section of 5 mm (0.197 in), and an outside diameter of 102 mm (4.02 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
It resists petroleum-based oils, many alcohols, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, low compression set under sustained load. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where automotive brake fluid or ozone and direct sunlight are present.
Typical settings include agricultural equipment, general industrial maintenance, and hydraulic and pneumatic systems.
Order part number H5X92, sold individually. Unit weight is approximately 7.3844 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.
