System Description
Trelleborg 601 Power-LockTM is integrated into the pipe during the manufacturing process. By heating the pipe and using the mandrel together with the seal as a tool to form the socket, the seal is effectively shaping its own groove. This reduces irregularities and tolerances in the socket.
Seal design & function
The Power-Lock™ is a composite seal consisting of:
-
A flexible rubber element to seal effectively against spigot and socket
-
A polypropylene reinforcement element, bonded to the rubber, which holds the seal firmly in place
The seal is equally effective under both positive and negative pipe pressure (vacuum). Under positive pressure the higher the pressure the greater the sealing force.
Under vacuum the seal maintains a positive sealing force against spigot and socket to prevent sand or soil entering the joint.
Seal Performance
Trelleborg 601 Power-Lock™ meets or exceeds current European and ISO standards for pressure, vacuum, deflection and shear load.
The seal design gives low assembly forces making pipe jointing easier. Improved productivity and lower scrap during belling process for the pipe producer when compare to traditional integrated seals.
Power-Lock™ tolerates ovality effects caused by transportation or storage of the pipe better than other integrated seals. Eliminates the risk of corrosion by removing metal inserts.

Video Joint Assembly
Step 1
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.
Step 2
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.
