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.
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:
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.

Inspect the spigot, socket and seal for damage and remove any dirt or dust prior to assembly. Chamfer the spigot end and remove all burrs.
Apply lubricant to the spigot end and immediately bring it into contact with the socket.
Align spigot and socket, and slide the spigot into the pipe, past the seal.
As the pipes are jointed the rubber sealing element is deformed and creates pressure against both spigot and socket resulting in a watertight seal.
