Review on 82 Ft XHF 1/2 Inch (13mm) 3:1 Waterproof Heat Shrink Tubing Marine Grade Wire Cable Adhesive Lined Tube Insulation Seal Moisture Corrosion Air Leakage Black by Chuck Derrick

Ive used adhesive lined shrink tubing before so I have something to compare. In this case I used the tubing to reinforce wood handles for wood clamps. Here are my impressions using the heat shrink.My application: I use pliers on the wood handles of wood clamps to get additional torque when tightening. The wood handles begin to get chewed up and eventually will just disintegrate. I used the heat shrink to reinforce and protect the wood handles from pliers. -- THIN GLUE: Other professional shrink tubing Ive used for outdoor electrical had a thick layer of internal glue that bubbled out when heated and provided a good water proof seal with its thick conformal coat of glue filling in any voids or cracks. The XHF shrink has a very thin layer of glue that is barely noticeable. When heat there is no indication of excess glue coming out the ends. I would not consider this shrink to provide a water proof connection as the glue clearly does not flow to fill in all voids. -- NOT 3 TO 1 SHRINK: The handles I wanted to cover were 1.125 diameter. When heating the 2" dia shrink it appeared to just barely conform to the handle. So I dont think its quite a 3 to 1 shrink ratio as the website states but closer to 2 to 1. -- NOT TOUGH MATERIAL: The professional shrink Ive used after shrink was a very tough material. I got the largest XHF tubing so that it would be the thickest wall after shrink. It does not hold up well to pliers and tears off when twisted. If it had a better and thicker glued inner wall it might have performed better.
