Ell-Jacs™ Plus Polyfilm lined Aluminum Elbow Covers are made in two, precision-formed, matching halves to cover and weatherproof insulated 45° and 90° pipe elbows.  Like our Aluminum Jacketing, Ell-Jacs™ Plus are a premier protective jacketing for insulation pipe systems and are a crucial accessory to complement the aluminum jacketing. Ell-Jacs™ Plus help protect the insulation and underlying pipe from physical damage, UV exposure, corrosive enviroments, and water. They also reduce the time and labor needed to install a metal jacketing system.
