Yes.  The standard models of the Torq-Tender have a black oxide finish, which gives mild corrosion protection to stand up to most industrial environments.  Where moisture, water spray, or other contaminants are present, special options are available including nickel plating, other plating, or stainless-steel versions.  Additionally, o-ring seals may be added to the housing to help seal the Torq-Tender to protect it from water and other contaminants.  Food Grade grease options are also available.  Please contact the factory if any of these special features are needed for your application.
