Abstract
A self-covering element for covering a pipe joint comprising of a deformable, hollow insulating element having a first portion and a second portion attached at an angle to one another. A longitudinal slit runs the length of the first and second portions, and a pressure sensitive adhesive with a removable release film is adhered to the longitudinal slit. The deformable insulating element allows for the entry of the pipe joint through the longitudinal slit, and surrounds the pipe joint. The pressure sensitive adhesive then seals the longitudinal slit and the pipe joint into the hollow cavity once the release film is removed.
