Unique polyethylene system for
the transportation of water
PUSH-FAST
GF0003-1 December 2009

www.durafuse.com
The unique Push-Fast system is one of the polyethylene product ranges offered
under the brand - DuraFuse. Manufactured by GPS, part of Aliaxis, this
innovative spigot and socket system is used for the transportation of water for
medium pressure applications up to 16 bar.
Push-Fast is a unique PE pipe and fitting system that requires no welding and
combines the benefits of polyethylene pipes with push-fit joints, making it an
ideal replacement for ductile iron and PVC systems. The system also conforms
to the requirements of the ductile iron European standard EN545.
Certificate No. FM 34819
The Push-Fast system has a specially designed socket, which
incorporates a tough thermoplastic grip ring and EPDM seal located
in a tapered groove. This allows the joint to resist end-thrust
generated by internal pressure and normally eliminates the need
for anchors or thrust blocks.
The grip ring and EPDM seal are each housed in their own separate
groove. The EPDM seal is leak tight over a wide range of pressures
and the seal is designed to increase its effect as the system water
pressure increases.
The grip ring is a reinforced plastic moulding with internal gripping
teeth and an external tapered section. Friction generated by axial
movement of the inserted pipe causes it to lock within the tapered
housing groove.
The water industry has traditionally used spigot and socket joints for
buried mains for ductile iron and PVC-U pipe works. The Push-Fast
system continues this conventional spigot and socket jointing
technique but enjoys the advantages a polyethylene system can
offer:
• Light-weight pipe and fittings
• Non-corrodible
• 50 year design life
• Flexibility
• Smooth internal bore
• Excellent chemical resistance
• Fully end load bearing
• Good insulation characteristics
The Push-Fast System
The most important feature of the Push-Fast system is the specially designed patented socket.
Standard lengths of pipe are supplied with a factory-welded socket on one end. A range of fittings are
available with plain, socket or flanged ends. The Push-Fast system can also be used in conjunction with
electrofusion fittings, providing even greater flexibility and an increased range of fittings to provide
off-takes and valves within the polyethylene pipeline system.
This unique system is the quickest way to lay a water pipeline in the marketplace and is the ideal
polyethylene solution for installers who would like to benefit from all the features of a PE pipeline
system without having to weld onsite.
Push-Fast fittings are available in PE100 black, SDR11 and SDR17, in sizes 90mm up to 250mm.
Various fitting arrangements can be made through the use of Push-Fast sockets, spigot fittings, pipe
and flanges to allow you to design a system that is unique to your needs.
Benefits of the Push-Fast System
• Quick and easy to install.
• Low skill level workers required.

Jointing Procedure
It is important to remember that the performance of the Push-Fast joint is dependant on the efficiency of the seal between
the elastromeric sealing ring, the pipe and the socket. Damage to the pipe or fitting or the presence of dirt or grit will
adversely affect the performance of the joint.
Factory fitted protective packaging should be left in position until the components are ready for use.
1
Remove protectors from spigots and sockets and inspect for damage, paying particular attention to any scoring of the
spigot. Scored spigots must be cut back to an undamaged section.

Apply the DuraFuse Push-Fast lubricant, spray or gel to the spigot, grip ring and the elastromeric
sealing ring in the socket. Typical usage of lubricant is as follows:
2
Push-Fast pipes are supplied with a factory machine chamfer. Any site cut pipes should be cut square and similarly
chamfered. The quality of the chamfer is important to ensure the seal performs optimally.

Inspect the elastromeric sealing ring and the respective locating grooves for any damage and replace if necessary.
If dirt or grit is present, the seal must be removed and the seal groove and socket thoroughly cleaned of all foreign
matter before replacing the seal.
Inspect the grip ring as above and remove any foreign particles without removing the grip ring from the socket groove.
Once all components are clean, it is important to ensure they remain clean by replacing protectors or plastic bags over
the ends unless jointing is to be carried out immediately.
The spigot ends of any site cut pipes should be marked with the insertion depth, using a suitable pipe marker:
8
Excessive use of lubricant on the joint may prevent the joint from locking correctly, particularly if
the lubricant is highly viscous in texture. We supply a recommended silicon lubricant and gel
suited for this application.
Align the pipe and fitting and enter the spigot into the mouth of the socket. Apply sufficient force
to the end of the pipe/fitting remote from the joint so that the spigot enters the socket up to the
marked insertion depth. Smaller sized pipe and fittings should be entered using hand-applied force,
where assistance of a crowbar and a wooden block may be necessary for larger sizes.

9
Under no circumstances should joints be pushed together using mechanical equipment..
Installation Hints and Tips
• The action of inserting the pipe into the socket can cause the grip ring to ‘float’ in its groove without
locking onto the pipe and therefore it may not engage fully unless subject to tensile loading or rapid
slight axial movement during pressurisation.
• Care should be taken not to move previously locked joints when progressively jointing pipe to socket
along a pipe run. If any back-to-back Push-Fast sockets are employed this is especially important and
a suitable fixing point must be applied to the fitting to prevent the second insertion disturbing the
first insertion. If the first insertion is disturbed it should be possible to re-lock both pipes by sharply
withdrawing the pipe from the second end. It is very important that the joint should not be further
disturbed.
Pressurisation
10
The final stage in the installation is to activate the Push-Fast joint. This is done following insertion by sharply
withdrawing the inserted pipe end from the socket to ensure the grip ring engages with the pipe surface and locks
in position.
During pressurisation the pipe is ejected up to 30mm. This initial displacement serves to lock the grip ring,
which will then resist further movement. Depending on the characteristics of each installation, the total
movement of the pipe over a long run during pressurisation will always be less than the sum of the individual
socket displacements. This is due to the incremental pipe length reduction upon pressurisation.
Large Diameter Pressurisation
With large diameter Push-Fast fittings (200mm+), one or both of the following strategies must be employed to
ensure joint integrity.
In either case pressurisation of a short section of pipe at a time is recommended:
Insert pipe up to stop
1. Ensure that the pipe cannot deviate from the line of the pipe run during pressurisation. Sideways
movement or bending allows the pipe to be ejected from the socket with low resistance. If the pipe
run is not straight, bends should be fixed in position.
2. Pressurise the system as quickly as possible to encourage locking of the grip ring. A long slow
pressurisation can cause the pipe to be ejected past the grip ring without being locked in position.
Return pipe until grip ring engages
11
Once the pipe has been inserted and locked the pipe and socket should not be disturbed.

Above Ground Installation
It is important that sufficient pipe supports of the correct type are
used in above ground installations to prevent sagging. These should
be positioned to permit axial movement.
Changes in pipe direction require sufficient strong fixings to prevent
any lateral movements. Resistance to axial movement may also be
required depending on the system layout. Pipe termination requires
high end-load resistance.
Standards and Approvals
All DuraFuse products are made in accordance with BS EN ISO 9001:
2000 and the Push-Fast system has undergone extensive testing and
trials to prove the long-term performance of the system. The system
conforms to all relevant water standards including WIS 4-32-17 and
BS EN 12201.
Product approvals have been obtained by SVGW in Switzerland and
Becetel in Belgium.
The system also has a number of independent water utility approvals
– contact us for further information.
