-141 BLACK BUNA 70D O-RING

The H70MD141 is an AS568-141 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 2.3 in (58.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.506 in (63.65 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists greases and lubricants, petroleum-based oils, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is known for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to polar solvents or ozone and direct sunlight will shorten service life.

This o-ring is metal detectable for HACCP and foreign-body control programs. Common environments for this compound include fluid power, agricultural equipment, and automotive.

This item is sold individually under part number H70MD141. Nominal inside diameter is listed as 2 5/16 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
