Trelleborg 605 Sewer-Lock™, integrated sealing systems for sewer ans stormwater plastic pipes

System Description

Trelleborg 605 Sewer-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 seal is equally effective under 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, preventing sand or soil to enter the joint.

The Trelleborg 605 Sewer-LockTM is a composite seal consisting of:

  1. A flexible rubber element to seal effectively against spigot and socket
  2. A polypropylene reinforcement element, which holds the seal firmly in place

Seal Performance

Trelleborg 605 Sewer-Lock™ seal meets or exceeds current European and ISO standards for wastewater lines both for indoor and underground.

Furthermore, the seal design gives low assembly forces making pipe jointing easier.



Trelleborg 605 Sewer-Lock™ seal is made from two materials. 

For dimensions up to 400 mm the sealing element is TPE and the plastic retaining element is polypropylene. The TPE material meets the European standard EN 681-2, class 60.

Oil resistant to EN 681-2 WH for dimensions above 400 mm the sealing element is EPDM rubber 50±5 IRHD which meets the European standard EN 681-1.

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.
