5.7MM CS X 51.6MM ID BLACK BUNA 70D

Ordered as H5.7X51.6, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 51.6 mm (2.031 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 63 mm (2.48 in). The o-ring compresses into its gland to block fluid or gas migration across a joint. Supplementary detail from the product record: Metric O-RING, JIS P52.

Buna-N (Nitrile) is specified for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. It resists hydraulic fluids, petroleum-based oils, and many alcohols. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or ozone and direct sunlight will shorten service life.

Typical settings include agricultural equipment, fluid power, and hydraulic and pneumatic systems.

H5.7X51.6 ships individually. Unit weight is approximately 5.6356 g. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
