Servi-Sert® Interchange

The Elster Perfection Servi-Sert Interchange head provides a safe and cost effective method for the replacement of in-service, service head adapter-style risers with minimal disruption to the customer premises.  Our patented step-by-step process allows for the removal and replacement of the old faulty or suspect service head adapter with Elster Perfection's Servi-Sert technology.  The same technology is used for our Permasert Coupling that provides a gas tight seal and pull-out strength greater than the connected PE piping.
