Such protective cap seals pipe ends against moisture, dirt and other debris thereby reducing or eliminating corrosion. Such protective cap reduces installation time as compared to removing tape and tape residue from each pipe end. The unique marker can indicate the purpose and identity of each underlying pipe or tube. Such protective cap also improves the visibility of the pipe ends during construction thereby increasing the safety of a job or construction site.Type: GrantFiled: March 2, 2010Date of Patent: February 11, 2014Inventors: John Oliver Shindelar, Stuart M Zinke
