XHF 3/32" 3:1 Waterproof 55Ft Clear Heat Shrink Tubing Marine Grade Wire Cable Adhesive Lined Tube Insulation Seal Against Moisture Corrosion and Air Leakage

Used it on a permanently coupled pair of outdoor extension cords. Was just big enough to fit over plugs and shrank tightly on the plugs. However, it did not shrink quite enough to fit snugly on the 1/2 inch diameter cord. Ended up using outdoor electrical tape to seal them. Product appears to be durable enough to withstand the harsh outdoor Midwest weather.

It glues as it shrinks to conform to shape creating a water tight barrier and is amazingly durable against nicks and scrapes. I used it on my hoes, cultivator, and barn rake to protect from rot. Also good for handle bar grips, fishing poles, walking sticks or anything like that. I used a butane torch to gradually shrink it and worked perfectly. I need to buy more now as it's something I need to keep on hand.

Very heavy duty. Know this - it’s very thick. So thick it looks a little awkward when it’s shrunk to size. Some reviewers overpromised on just how much it shrinks but I got it to 1/3 to 1/2 the original size before it starts to deform. I used heat gun and butane torch with same results. I’d say it’s pretty good.

This could be good or bad, depending on your application, but the tubing wall is quite thick. I measure it as 0.68mm before shrinking and it is, if anything, thicker after shrinking - perhaps 1mm. My intended use was for labeling XLR connectors on audio cables, but the tubing is thick enough that it's hard to work with.

Grip on paddles tore replace with this going on third season.
