1.5MM CS X 20MM ID BLACK BUNA 70D

Ordered as H1.5X20, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 20 mm (0.787 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 23 mm (0.91 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists water, greases and lubricants, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is known for reliable performance in both static and dynamic service, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

You will find this material specified across construction equipment, fluid power, and general industrial maintenance.

H1.5X20 ships individually. Unit weight is approximately 0.1492 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
