-043 BLACK BUNA 90D O-RING

APG stocks the H90043, an AS568-043 black Buna-N (Nitrile) 90 Shore A O-Ring built to an inside diameter of 3.489 in (88.62 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.629 in (92.18 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists propane and butane, many alcohols, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with ketones or automotive brake fluid.

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

This item is sold individually under part number H90043. Unit weight is approximately 1.0133 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
