5.7MM CS X 84.6MM ID BLACK BUNA 70D

APG stocks the H5.7X84.6, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 84.6 mm (3.331 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 96 mm (3.78 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope. This item is further identified as Metric O-RING, JIS P85.

It resists many alcohols, hydraulic fluids, and water. That behavior comes from the compound itself: Buna-N (Nitrile) offers 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. It is not the right choice where strong acids or ozone and direct sunlight are present.

Maintenance and OEM teams specify it across automotive, hydraulic and pneumatic systems, and construction equipment.

H5.7X84.6 ships individually. Unit weight is approximately 8.9052 g. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
