Seal design & function
Trelleborg 552 Anger-Lock IPS locked-in seal is a combined lip and compression seal which is installed inside the socket after it has been formed. Making the seal an integral part of the pipe eliminates many of the disadvantages of separate sealing rings.
The unique design comprises of a rubber sealing element bonded to the plastic retaining element which holds the seal securely in position during transport and pipe assembly.
The seal is designed to absorb any permissible variations in the groove.
Seal Performance
Trelleborg 552 Anger-Lock IPS joint meets or exceeds current European and American 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.
