Seal design & fuction
Trelleborg 605 Sewer-Lock 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-Lock is a composite seal consisting of a flexible rubber element to seal effectively against spigot and socket and a polypropylene reinforcement element, which holds the seal firmly in place.
Key features & benefits
- Greater joint reliability due to joint tolerance reduction
- Fully automated insertion eliminates risk of human error
- Low jointing force, eliminating risk of seal displacement
Material
- Synthetic rubber (EPDM) or Thermoplastic elastomer (TPE)
- Hardness 50+/-5 IRHD or 60+/-5 IRHD

Dimensions & designation
On each seal, profile, diameter and appropriate pipe dimensions together with date of manufacture is given. The corresponding information is also included on the packaging.
Subject to change for technical reasons.
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.
