-275 BLACK BUNA 70D O-RING

Part number H70MD275 is an AS568-275 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 10.484 in (266.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.762 in (273.35 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is specified here for reliable performance in both static and dynamic service, low compression set under sustained load. The material holds up against hydraulic fluids, water, and greases and lubricants. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Verify compatibility before use with ketones or polar solvents.

The compound is metal detectable for HACCP and foreign-body control programs. It sees regular use in automotive, agricultural equipment, and fluid power.

H70MD275 ships individually. Nominal inside diameter is listed as 10 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
