5.7MM CS X 52.6MM ID BLACK BUNA 70D

The H5.7X52.6 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 52.6 mm (2.071 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 64 mm (2.52 in). This o-ring compresses into its gland to block fluid or gas migration across a joint. Source specification: Metric O-RING, JIS P53.

Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, low compression set under sustained load. This material stands up to propane and butane, hydraulic fluids, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to ketones or polar solvents will shorten service life.

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

H5.7X52.6 ships individually. Unit weight is approximately 5.6899 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.
