Telescopic sleeves

Telescopic sleeves are a penetration seal that provides a flexible connection between riser pipe and manhole in gravity systems. The range comprises three versions: one sleeve for infra riser pipes in concrete manholes, and two for plastic manholes with outside diameter 400 mm, one for double-wall type riser pipes and one for smooth riser pipes. All are designed for riser pipes with an inside dimension of 315 mm. The sleeve is manufactured in EPDM rubber, which provides an elastic, flexible sealing fit against the pipe surface. Like IBECO's other sleeves, it is designed for flexible connection of pipes to concrete manholes, concrete pipes and concrete walls, where the hole can be either precast or drilled.
