The shape of the tube supports allows them to be inserted easily
in the tube. One end of the EO support sleeve is enlarged on
its external diameter by a knurl. On insertion, this knurl forces
itself into the interior wall of the tube and secures the sleeve
against shifting or falling out during assembly and without wid-
ening the tube end.
Steel tubes made of 37.4 or soft metal tubes can be checked in
accordance with Figs. S45 and S46, respectively, to see if they
require support sleeves; for plastic tubes, (support) sleeves are
always necessary
(see Page E15
for E type sleeves).
For stainless steel tubes of material 1.4571/1.4541, refer to Fig.
S44 to determine the need for a support tube.

Steps for Proper Assembly of Support
Sleeve (VH)
Step 1 –
Insert support
sleeve up to knurl.
Step 2 –
Drive knurled end
of support into tube.
Step 3 –
Ensure that sup-
port sleeve is flush with
tube end.
Step 4 –
Pre-set progres-
sive ring following one of the
pre-setting methods covered
