3MM CS X 42MM ID BLACK BUNA 70D

Ordered as H3X42, this is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 42 mm (1.654 in), a cross section of 3 mm (0.118 in), and an outside diameter of 48 mm (1.89 in). The o-ring delivers dependable bidirectional sealing in a compact groove envelope.

This material stands up to hydraulic fluids, many alcohols, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to strong acids or ozone and direct sunlight will shorten service life.

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

This item is sold individually under part number H3X42. Unit weight is approximately 1.23 g. Review your operating media and conditions against this specification before installation.
