Heat-shrink tube

for sealing the top end of the universal grommet


Simply slip the heat-shrink tube over the top end of the universal grommet, then evenly heat the universal grommet and outflowing pipe, cable or similar line on all sides. The heat-shrinking tube sections will shrink to form a seal, with the hot-melt adhesive on the interior capable of reliably sealing even the smallest of gaps. This creates a permanent seal. A hose clamp can also optionally be used to provide an extra secure hold of the position.


Polyolefin heat shrink tubing with hot-melt adhesive on the interior. The material is durable for use in temperatures ranging -55° C to 110° C with high tensile strength (>14 MPa) and elasticity (elongation at break 400%). It is also resistant to fungi, decay and UV radiation.
