6MM CS X 115MM ID BLACK BUNA 70D

Part number H6X115 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 115 mm (4.528 in), a cross section of 6 mm (0.236 in), and an outside diameter of 127 mm (5 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to propane and butane, petroleum-based oils, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, low compression set under sustained load. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ozone and direct sunlight or strong acids.

Maintenance and OEM teams specify it across fluid power, agricultural equipment, and general industrial maintenance.

H6X115 ships individually. Unit weight is approximately 13.306 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
