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 St 35.4 or 37.4 or soft metal tubes can be
checked in accordance with Figs. T44 and T45,respectively,
to see if they require support sleeves; for plastic tubes, (sup-
port) sleeves are always necessary (see Page F15 for E type
sleeves).
For stainless steel tubes of material 1.4571/1.4541, refer to Fig.
T46 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
earlier ( page T24).The sup-
port sleeve prevents collapse
of tube.
