Type OR is a robust conduit with a galvanised steel core and thick, smooth oil resistant PVC cover - a construction that provides good mechanical protection of cables and resistance to aggressive oils and greases. When exposed to these substances, the conduit retains its flexibility and does not stiffen or rupture. Type OR is used in many applications including machines where metalworking fluids are used, on diesel-engines, generator-sets and machines and equipment in the metal, paper, chemical and petrochemical industry.
