System Description
Seal design & function
Trelleborg 576 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 unique design comprises of two elements:
- A plastic retaining element that holds the seal securely in position
- A rubber sealing element that ensures a watertight seal once the pipes are jointed
Together, they absorb any permissible variations in the groove.
Made of EPDM rubber, approved for drinking water application.
Seal Performance
Trelleborg 576 Anger-Lock™ (metric) joint meets or exceeds current European Standards for pressure, vacuum, deflection and shear load.
The seal design gives low assembly forces making pipe jointing easier.

Subject to change for technical reasons
Joint Assembly
The spigot and socket of the pipe should be checked for damage prior to jointing.
The pipe spigot should be chamfered with an angle of 15°, taking care to remove all burrs. Both spigot and socket including the sealing ring should be free from dirt and other foreign matter.
Lubricant should be applied evenly to the spigot end of the pipe.
Immediately after lubrication, the spigot should be brought into contact with the socket.
Both spigot and socket should correctly aligned and then slide the spigot into the socket, thus compressing the seal until the joint is fully made.
