Please read these instructions fully
before starting to fit the seal.
Check that all components of the seal
are present.
Each set comprises:
!1 off elastomeric sealing element
(either for internal seal or external
seal).
!2 off scarf-split plastic anti-extrusion
rings (either for internal seal or
external seal).

Ensure that the Teesele is the correct
size and type for the housing.
Inspect all seal components to ensure
they are in good condition and have not
been damaged during storage.
Clean the housing and inspect for sharp
edges, burrs or any other areas that
could damage the seal. Repair housing
where necessary.
A: Internal seal applications
Position one plastic anti-extrusion ring on
each side of the elastomeric element's
raised sealing face. Do this by closing the
plastic ring slightly at its scarf split then
opening it on to one of the flat surfaces of
the element. The rings are identical and
can be used on either side of the
elastomeric element.
After Installation check that the
rings are seated correctly.
anti-
extrusion
Do not overstress the rings during
this operation.
Insert the elastomeric sealing element into
the housing groove in the bore. If
necessary, deform the
element into a
crescent shape
and position it
into the groove.
Ensure that
sealing element
is seated
correctly with no
twists, creases or kinks.

Fitting Guide for
Ensure that rod end has a 15°-20° lead-in.
Align the rod carefully, and insert it until it
just touches the seal, then press the rod
®
firmly through the seal bore. The Teesele
is now installed.
Align rod and firmly press through
seal bore.

B: External seal applications
Ensure there is a 15°- 20° lead-on
at the end of the rod.
15°- 20°
Stretch the elastomeric sealing element
over the rod, using the 15°-20° lead-on to
aid stretching. It is advisable to stretch
the seal ID to a size greater than the
cylinder bore. Push the elastomeric
element along the rod until it locates in the
housing groove correctly.
Note: the elastomer may need time to seat
in the groove, depending upon the
environmental temperature.
A thin film of system compatible lubricant
may be used (if in doubt, please contact
James Walker or the equipment
manufacturer).
not
If elastomeric sealing element cannot be stretched
sufficiently, then warm it for about 30 minutes at 100°C
in a conventional oven. Once warmed, follow the fitting
guide instructions shown above. Follow local Health &
Safety regulations for handling of hot items.
Allow elastomeric element to return to ambient
temperature, then check that it is seated properly.

100°C 30 mins
When the elastomeric sealing element
must pass over a threaded or abrasive
surface, cover the rod surface to protect
the seal. When passing over grooves,
these should be filled to allow smooth
transit of seal components.

Fitting Guide for
Open up each plastic anti-extrusion ring
at its scarf split to form a helix. This will
allow the ring to slip over the rod without
over-stressing the ring material.
Position one ring on each flat side of
elastomeric element. The rings are
identical and can be used on either side
of the element.
After Installation check that the
rings are seated correctly.

Material Safety Data Sheets are available on request
Health warning:If PTFE or fluoroelastomer (eg, FKM, FFKM, FEPM) products are heated to elevated temperatures, fumes will be produced which may give unpleasant effects, if inhaled. Whilst some
fumes are emitted below 250°C from fluoroelastomers or below 300°C from PTFE, the effect at these temperatures is negligible. Care should be taken to avoid contaminating tobacco with particles of
PTFE or fluoroelastomer, or with PTFE dispersion, which may remain on hands or clothing.
