NOTES
These instructions relate to the UltraGrip range of Couplings for
use on the pipe materials noted in the table.
UltraGrip is supplied fully assembled for use as an end restraint
(gripping) product and should not be dismantled prior to
installation, unless it is to be used as a flexible (non gripping)
product in which case the only components to be removed are
the red grippers.
* Site test pressure = 1.5 times working pressure
Thick pipe coatings and protective wrappings must
always be removed
1. Check that pipe material and size are suitable for the UltraGrip Coupling. For PE always
use a support liner, for PVC use a support liner when required (Ref Table 1).
2. Examine pipe ends and ensure that pipe surfaces are clean and free from score marks, scale,
rust or any loose debris or other surface defect that may affect fitting performance. Weld beads
must be ground flush, maintaining correct surface profile. Thick pipe coatings or wrappings
must always be removed. UltraGrip must seat either on to the bare pipe surface or on a thin
paint film.
3. Safe Handling Measures: When manoeuvring the product from packaging to pipe surface,
please ensure that correct manual handling procedures are adopted. When mechanical lifting
aids are required, ensure that the use of safe working practices is adopted and all lifting
equipment is rated for the loads.
4. All UltraGrip couplings incorporate hygiene protective caps to prevent contamination.
This must be removed prior to fitment (Fig 1).
5. Align pipe to be laid with pipe already in position, taking care that pipe ends are concentric,
adjusting support or trench bed as necessary. The enhanced gasket technology employed does
not require the use of any lubricant; therefore ensure no lubricant is applied.
Decide now what type of connection is required: GRIPPING or NON-GRIPPING:-
GRIPPING - When used as a gripping type (only for buried applications), the fitting must be
installed as supplied, with the gripper strips in position (Fig.2 a). Check if all grippers are
inserted correctly.
NON-GRIPPING - When used as a non-gripping type, the gripper strips have to be removed.
Simply slide out the gripper strips (Fig.2 b). When installed as a flexible (non-gripping) product
UltraGrip does not prevent pipe pull-out and adequate external restrain has to be provided.
6. To ensure correct installation, mark the minimum and maximum pipe insertion depths obtained
from Table 1 around the full circumference of both pipe ends as shown in Fig.3. Align the
pipes and centralise the UltraGrip Coupling over both pipe ends, ensuring that both pipes are
inserted to a depth between T(min) and T(max) as shown in Fig.4.
7. Before tightening the UltraGrip bolts ensure that each bolt head is captivated securely. Tighten
diametrically opposed fasteners, giving each nut one or two turns at a time to draw up the end
ring evenly. All nuts are to be tightened up as many times as necessary to achieve the required
bolt torque as defined in Table 1. On completion, there should be an even radial gap between
pipe and end ring of the fitting with all of the T(max) line being visible and none of the T(min)
2
line being visible. Repeat the exercise on both ends of the Coupling.

Above ground exposed pipework is subject to both loads from
the internal pressure and those from temperature changes
/ thermal expansion, which can be substantially higher than
those from internal pressure and cannot always be safely
determined. For this reason it is recommended that the use of
UltraGrip be restricted to buried pipelines, valve chambers and
above ground indoor applications not exposed to direct sunlight
or excessive temperature changes (e.g. pump houses).
