AquaFast Coupling
The AquaFast couplings is supplied pre-assembled and should not be dismantled
prior to installation.
B
1) AquaFast coupling is suitable for use on the following pipe materials :-
• Metric PVC pipe
• MDPE (PE80), HPPE/HDPE (PE100) Polyethelene pipe – SDR17/17.6 & SDR11
Support liners should not be used with AquaFast for any installation.
The AquaFast couplings can also be used to join Metric PVC to PE pipe.
Installation of AquaFast Coupling :-
2) Check that the pipe material, diameter and wall thickness
(if used on PE) are suitable for the AquaFast coupling.
Ensure that the pipe surface is clean and does not have any score marks that
may provide a leak path under the gasket and that the cut end is square.
3) To aid installation, mark both pipe ends at a distance slightly greater
than half the overall length of the AquaFast coupling. (See Fig 1)
4) Slide the AquaFast coupling fully onto either the pipe already
in position or the one to be laid. (See Fig 2)
5) Align the two pipes and adjust the setting gap (See Fig 3), ensuring it is between
the minimum and maximum values as set out in the following 'Setting Gap Table'.
6) Using the marks made in (3), slide the AquaFast coupling to a central
position over the pipe ends (See Fig. 4) and commence bolt up.
7) Working round the AquaFast coupling, evenly tighten the bolts giving each
nut one or two turns at a time to draw up the end rings evenly. For couplings
having over 2 bolts, tighten diametrically opposed bolts giving the nuts
one or two turns at a time drawing up the end ring evenly. (See Fig 5)
8) The metal to metal "Positive Stop" feature of the AquaFast fitting means that
installation is completed when the end rings, intermediate ring and centre sleeve
components are all in contact with each other. The resisters between the end
ring and the intermediate ring do not need to be fully compressed. (See Fig 6)
