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
Aging resistant & weather resistant – Withstands UV, ozone, and sun exposure for long service life
Easy installation – No tools required, simply slide into place
High radial pressure – Excellent rebound performance for a tight seal
Mechanical damage resistance – Outstanding tear and abrasion resistance
