Trelleborg 165 Integrated Pipe and Manhole Seal, Sealing System for Sewer and Stormwater Concrete Pipes

System Description

Trelleborg 165 is a one-piece integrated seal for concrete pipe systems. It ensures a watertight seal between pipes, manhole sections and pipe connections to manholes. The seal is cast into the socket during pipe manufacture. This secures the seal in the correct position, minimizing the risk of seal displacement.

Seal design & function


Trelleborg 165 is co-extruded, using specially formulated EPDM rubber compounds of two hardnesses to form the perfect seal:

  1. The forming part, made of hard rubber (70 IRHD), ensures a secure and accurate joint profile during casting

  2. The sealing part, made of soft rubber (50 IRHD), is a combined lip and compression seal

  3. Holding sections are cast into the concrete during pipe manufacture, securing the seal in the correct position

  4. Slurry lips against the pallet prevent ingress during concrete compaction

Joint Assembly

Forheda 165. Trelleborg

Check that the socket and spigot are in good condition and free from mud and gravel. Apply lubricant to the spigot. This should be spread evenly over the surface paying special attention to the front radius of the spigot.

Center the spigot into the socket and push the pipes together. The seal design prevents concrete to concrete contact.
