304 AND 305
SERIES ENTRY SEALS
PIPING &
CONTAINMENT
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. The
spigot on both sides of the 305 allow for EIF welding. The seal is fully vacuum and
pressure testable ensuring 100% leak-free seals and sumps.
