.187" C/S (3/16" ACTUAL) (4.75 MM)

Part number 0284187 is a black Buna-N (Nitrile) 70 Shore A O-Ring Cord Stock with a cross section of 0.187 in (4.75 mm). An o-ring cord stock lets you fabricate a custom-size seal on site by cutting and splicing to the required circumference.

Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer and low compression set under sustained load. The material holds up against petroleum-based oils, greases and lubricants, and many alcohols. Exposure to ozone and direct sunlight or strong acids will shorten service life.

Typical settings include hydraulic and pneumatic systems, agricultural equipment, and general industrial maintenance.
