-127 BLACK BUNA 90D O-RING

Ordered as H90127, this is an AS568-127 black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 1.424 in (36.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.63 in (41.4 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against greases and lubricants, hydraulic fluids, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

Maintenance and OEM teams specify it across automotive, fluid power, and construction equipment.

Stocked as H90127 and sold individually. Unit weight is approximately 0.879 g. Review your operating media and conditions against this specification before 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.
