-132 BLACK BUNA 70D O-RING

Part number H70132 is an AS568-132 black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 1.737 in (44.12 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.943 in (49.35 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to greases and lubricants, propane and butane, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) offers low compression set under sustained load and the most widely specified general-purpose sealing elastomer. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving ozone and direct sunlight or strong acids call for a different compound.

You will find this material specified across construction equipment, agricultural equipment, and fluid power.

H70132 ships individually. Unit weight is approximately 0.96 g. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
