Trelleborg 171 Pre-Lube Load distributor is a sliding seal with a prelubricated closed sliding mantle resulting in low jointing force as there is no friction between rubber and concrete.
The joint design should comply with the requirements of Din V 4034-1. Connected to the seal is a load distributor element which prevents concrete to concrete contact between the manhole sections.
