1MM CS X 100MM ID BLACK BUNA 70D

APG stocks the H1X100, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 100 mm (3.937 in), a cross section of 1 mm (0.039 in), and an outside diameter of 102 mm (4.02 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The compound resists water, petroleum-based oils, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) offers reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or strong acids.

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