Branch Connections for Water and Gas Pipe

The UPE UnderPressure Tee offers the customer a robust and
flexible means of taking flanged connections off both water
and gas mains in sizes between 80 mm and 1,200 mm in
diameter.
Branch connections for
new installations or
underpressure drilling
operations

The universal tolerance and elastomeric seals ensure an
easy to assemble and leak free connection on all rigid pipe
materials including Ductile Iron, Cast Iron, Steel and uPVC pipe.

Benefits
Ideally suited to underpressure
drilling operations for both water
and gas mains
Large universal tolerance provided
by elastomeric seals at each gland
ring for sizes up to 600mm (24”)
Strong and robust design for safer
drilling operations, especially on
size for size drilling
High performance elastomeric
seals provide effective sealing on
pitted or corroded pipework
Suitable for use with flanged
drilling and line stopping
equipment
Robust design can cope with the
high radial and axial forces
encountered during underpressure
drilling operations and often
encountered during flow stopping
(stopple) operations
