3.5MM CS X 14MM ID BLACK BUNA 70D

Part number H3.5X14 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 14 mm (0.551 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 21 mm (0.83 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

Expect good resistance to water, many alcohols, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or ozone and direct sunlight will shorten service life.

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

H3.5X14 ships individually. Unit weight is approximately 0.65 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
