5MM CS X 54MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 54 mm (2.126 in), a cross section of 5 mm (0.197 in), and an outside diameter of 64 mm (2.52 in), catalogued under part number H5X54. It compresses into its gland to block fluid or gas migration across a joint.

Expect good resistance to many alcohols, propane and butane, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs and low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with polar solvents or strong acids.

You will find this material specified across agricultural equipment, automotive, and fluid power.

Reference part number H5X54 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
