Trelleborg Anger-Lock is a combined lip and compression seal. Installed inside the socket after it has been formed, the retaining element effectively locks the seal into the groove.
Making the seal an integral part of the pipe brings many advantages: rings can no longer get lost during stocking and transportation, and the low jointing force ensures that the seal stays in place when pipes are jointed.
The design comprises of a plastic retaining element that holds the seal securely in position and a rubber sealing element that ensures a watertight seal once the pipes are jointed. Together, they absorb any permissible variations in the grove.
The system meets the requirements of European and American Standards for the supply of water and can also be used for wastewater applications.
