SEAL DESIGN AND FUNCTION
Trelleborg 505 DWC EasyLock is a combined lip and compression
sealing system that is positioned in the groove of the double wall
corrugated (DWC) pipe.
Symmetrical by design, there is no chance of error when mounting
the seal onto the pipe. The material and design allow for the lowest
possible jointing force.
Once jointed, the Trelleborg 505 will absorb any permissible variation
in pipe geometry whilst maintaining a high sealing performance.
The material chosen, SBR vulcanized rubber, offers excellent
resilience, strength and resistance to abrasion and materials
present
in wastewater. This makes it the perfect choice for non-pressure
underground drainage and sewage systems.
The Trelleborg 505 DWC EasyLock meets or
exceeds current international standards.

Clean the socket and 1
st
spigot groove and mount
the seal into the groove.
Apply lubricant to the
seal before assembly.
Slide the spigot into
the socket, thus com-
pressing the sealing lip.
When the pipes are
assembled, the rubber
sealing element is
designed to deform.
This creates pressure on
both spigot and socket,
ensuring a watertight
seal.
Pipes with Trelleborg 505 seals must be laid
in accordance with applicable standards and
regulations.
Please contact Trelleborg Pipe Seals for technical
advice and joint design recommendations to meet
your performance requirements.
