Seal design & function
Trelleborg 582 Din-Lock is a combined lip and compression seal. Installed inside the socket after it has been formed, the retaining element effectively locks the seal into the groove.
Making the seal an integral part of the pipe brings many advantages: rings can no longer get lost during stocking and transportation, and the low jointing force ensures that the seal stays in place when pipes are jointed.
The unique design comprises of two elements: a plastic retaining element that holds the seal securely in position and a rubber sealing element that ensures a watertight seal once the pipes are jointed. Together, they absorb any permissible variations in the groove.
Key features & benefits
- Cannot be displaced during transport & installation
- Fully fills the groove to prevent dirt intrusion before joint assembly
- TPE-V for increased oil resistance
Material
- Thermoplastic elastomer (TPE)
- Hardness 60+/-5 IRHD

Joint Assembly
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.
