7MM CS X 425MM ID BLACK BUNA 70D

The H7X425 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 425 mm (16.732 in), a cross section of 7 mm (0.276 in), and an outside diameter of 439 mm (17.28 in). This o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against water, greases and lubricants, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or ozone and direct sunlight are present.

It sees regular use in automotive, hydraulic and pneumatic systems, and construction equipment.
