Petrolatum cold applied wrap tape is a type of protective tape that is used to wrap around pipes, valves, and other metal surfaces to prevent corrosion and damage. It is made of a flexible material that can conform to the shape of the surface being wrapped, providing a tight seal that prevents moisture and other corrosive elements from reaching the metal underneath.
