-176 BLACK BUNA 90D O-RING

H90176 is an AS568-176 black Buna-N (Nitrile) 90 Shore A O-Ring with an inside diameter of 9.237 in (234.62 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 9.443 in (239.85 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against many alcohols, water, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or ozone and direct sunlight are present.

Typical settings include construction equipment, general industrial maintenance, and agricultural equipment.

H90176 ships individually. Unit weight is approximately 5.4303 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
