Product
Description:
The
built-in
mastic
cold
shrink
tube
is
a
waterproof
sealing
product
specially
designed
for
outdoor
cable
and
connector
protection.
This
built-in
mastic
cold
shrink
tube
comes
with
pre-coated
mastic,
eliminating
the
need
for
additional
filling.
The
mastic
cures
without
leaking,
providing
highly
reliable
flow
sealing.
Both
ends
of
this
built-in
mastic
cold
shrink
tube
seal
tightly
against
the
cable
wall,
effectively
preventing
rainwater
ingress.
With
excellent
aging
resistance
and
weather
resistance,
this
built-in
mastic
cold
shrink
tube
offers
long
service
life.
It
is
widely
used
for
waterproof
sealing
of
coaxial
cables
at
telecom
base
stations,
CATV
connectors,
N-type
connectors,
1/2
jumpers,
DIN
heads,
wire
and
cable
connections,
and
other
types
of
insulation
sealing.
Application Scenarios:
Waterproof sealing for coaxial cables at telecom base stations
N-type connectors
1/2 jumpers
DIN heads and 1/2 jumper connectors
Waterproof sealing for CATV (cable TV) connectors
Wire and cable connections
Other types of connection and insulation sealing
Key Features:
Cures without leaking – The built-in mastic solidifies without overflow, providing highly reliable flow sealing
Both ends seal tightly – The inner walls at both ends of the cold shrink tube seal firmly against the cable, effectively preventing rainwater ingress
