Casing Coupling Protective Sleeve
When
rubber
vibrator heads are used, it is advisable to place
a
protective sleeve
over the flexible shaft casing coupler.
This will protect epoxy coated rebar from being damaged.
Please follow the instructions listed below to install the
protective sleeve. Reference Figure 8 when performing the
installation of the protective sleeve.
Slide the casing cover protective sleeve onto and the
flexible shaft (vibrator end).
Using a open end wrench and locking type pliers, attach
vibrator head to flexible shaft. It is recommended to
apply a small amount of pipe thread sealant on the casing
coupler threads to prevent water from entering the
vibrator head.
Apply a uniform 3/8” bead of adhesive about 4-inches
long over the casing coupling.
Push casing coupling protective sleeve over flexible
shaft coupling, rotating sleeve as you push, until end
of sleeve enters recess on vibrator head.
Make sure to place a bead of adhesive at the opposite
end of the sleeve to prevent wet concrete from entering
the opening.

It will take approximately
one hour
for the sealant to set (cure) so that
the protective sleeve will stay in
place during operation.
