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.
Trelleborg 165 is co-extruded, using specially formulated EPDM rubber compounds of two harnesses to form the perfect seal:
- The forming part, made of hard rubber (70 IRHD), ensures a secure and accurate joint profile during casting
- The sealing part, made of soft rubber (50 IRHD), is a combined lip and compression seal
- Holding sections are cast into the concrete during pipe manufacture, securing the seal in the correct position
- Slurry lips against the pallet prevent ingress during concrete compaction
Key features & benefits
- Cast into pipe or manhole during manufacture
- Cannot be displaced during stocking or transportation
- Saves time during installation
Material
- Synthetic rubber (EPDM)
- Hardness 50+/-5 IRHD (Sealing part)
- Hardness 70+/-5 IRHD (Forming part)

Dimensions and designation
On each seal, profile thickness, outer diameter, recommended pipe measurement and production period are given. The corresponding data are also on the packaging.
Subject to change for technical reasons.
Joint Assembly
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.
