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.
HIGHLIGHTS
• Electrofusion seal for 40/32 mm pipe.
• 302-040 seal complements 32 mm pipe range.
• 40 mm secondary (double wall) pipe welds directly to seal
spigot using 02.40(SC) fusion coupler.
• 32 mm primary (single wall) continues through penetration
and into PE sump/chamber and is fusion sealed with
49-040-032 (ordered separately).
