Thermo Tube
(medium wall tubing with hot melt adhesive)
Specification
Medium Wall Thermo Tube is used for low voltage insulation over lugs and ferrules.
Tubes coated on the inside with hot melt adhesive are also used for external protection of joints.
On shrinking, the adhesive melts and seals the joints against dust and moisture.
