ENTRY SEAL
These electrofusion entry seals weld directly to the walls of
polyethylene chambers or sumps. They have been specifically
designed to reduce the number of fittings necessary to provide
watertight seals between the underground tank sump/chamber
and the UPP® primary or secondary contained pipe and electrical conduit or duct. The nature of the seal means that after
installation it becomes one with the sump, with zero leak paths,
creating a 100% leak tight system. The seals are polyethylene
based allowing electrofusion of UPP® pipework systems directly
to the penetration, negating the need for mechanical boots and
creating a homogeneous structure of the sump, boot and pipe.
