-456 BLACK BUNA 90D O-RING

Part number H90456 is an AS568-456 black Buna-N (Nitrile) 90 Shore A O-Ring supplied with an inside diameter of 13.475 in (342.27 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 14.025 in (356.24 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against petroleum-based oils, greases and lubricants, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where automotive brake fluid or ozone and direct sunlight are present.

Typical settings include agricultural equipment, construction equipment, and automotive.
