End cap HDPE 75mm used widely today in Europe for lines installations of water supply infrastructure and lines for the transport of natural gas. The end cap mounted by the method Butt-fusion. End cap enables terminal closure the HDPE pipe network. For welding End Cap using a welding machinery which supplies power to control reziztencën of End Cap, this resistance generates heat needed the union by merging the inside part of electrocoupler and exterior of HDPE pipe. Manufactured with European standards, resistant to corrosive materials, high resistance to deformation of land and resistant to pressure up to 16 Bar.
