QSZH-125 Tubing
Sealing and protection
of inline wire splices
and grounding ring
terminals.
QSZH-125 Tubing
Zero halogen, dual wall heat-
shrinkable tubing designed to
provide environmental sealing,
mechanical and electrical
protection of in-line splices in
an automotive environment.
The tubing is centred over the
splice area and on heating the
adhesive melts and is squeezed
around where the wires are
crimped or welded and between
wire cores by the shrinking
action of the sleeve. The installed
QSZH-125 tube provides low
profile mechanical protection
against flexing, abrasion and
cut-through as well as electrical
insulation.
Benefits
There are five QSZH-125 sizes
to cover a wide range of typical
automotive splice configurations
having a maximum of seven
wires on either side.
The sleeves are marked
1, 2, 3, 3A and 4 to denote the
size.
