Connecting valves and fittings with a threaded connection

can be time-consuming and often, it leaves part of
the thread exposed to the medium and the external
environment. Over time this will cause corrosion of the
uncoated thread and may even result in a leakage.
Supa Lock™ solves this problem.

 Self-locking safety retainer
Supa Lock™ is designed as a tensile joint
and withstands pressures up to PN16 x 1.5.
The safety retainer is designed with an edge
(1), which makes it self-locking whenever
there is pressure in the pipeline. Therefore, no
accidental disassembly can take place. The
safety retainer has two finger knobs (2) for easy
assembly and disassembly.

No rotation of valves and connectors

Free rotation is restricted for the valves and the
threaded connectors used for drilling machines
to enable effective drilling. Small cast notches
placed on the outer rim of the socket end and
on the inner rim of the spigot end interlock and
prevent rotation.

 Supa Lock™ valves
Supa Lock service connection valves in ductile iron are of the renowned AVK design
and are available with Supa Lock™ spigot end X Supa Lock™ socket end or PRK
coupling, and the angle valves are available with Supa Lock™ socket end or push-
in socket end. The brass ball valves are available with Supa Lock™ spigot end X
threaded end, PRK coupling or tensile screw coupling.

Supa Lock™ tapping saddles

Supa Lock™ tapping saddles are available in variants for PVC/PE pipes and for
iron/steel pipes and with/without blade shut-off. A large profiled rubber gasket
of drinking water approved EPDM rubber ensures a drop tight seal against the
pipe, and A4 nuts located in a recess ease the installation and prevent them from
rotating when tightening the bolts.

The tapping saddles for blade shut-off act as a temporary valve during the
drilling process. The tapping head is a low-cost alternative to a valve, but without
possibility of operation from ground level.

Supa Lock™ fittings

The wide range of Supa Lock™ fittings includes straight and angled push-in
fittings, fittings with PE end for direct welding into PE pipes, fittings with PRK
and tensile screw couplings, spacers serving as access point to the pipe without
tapping, 3-way socket fittings for branching off the pipeline, double spigot fittings
for reversing male/female connections, socket and spigot fittings serving as tapping
point for service connections, sensor fittings, blind flanges and plugs, etc.

The angled fittings can be rotated 360° once installed, thus offering great flexibility.
The free rotation of the joint allows the installer to direct the service pipe outlet
in any direction from the main pipe, thus avoiding collision with other pipes or
obstacles in the ground.

Supa Lock™ threaded connectors

The threaded connectors with internal thread for connection to drilling machines are
available in ductile iron or brass. They are designed with rotation stop to prevent the
fitting from rotating during the drilling process, and can of course be reused. The
transition connectors with external thread are used to connect a threaded system to
the Supa Lock™ system.
