3/8 Inch Heat Shrink Tubing - 25Ft 3:1Ratio Waterproof Heat Shrink Tubin - Adhesive Lined,Dual Wall Adhesive Shrinkable Wire Wrap Tube - Black (1, Black, 3/8"(9.5mm)-25Ft)

Pretty good I don't know what the original use is for this but this works really good as a grip for a pool stick or fishing rod or anything like that as well Even a baseball bat maybe another market you could put in your categories

I'm a retired professional mechanic who specialized in electrical. I installed stereos way back in the CB days. I've used lots and lots of heat shrink and and know a good quality shrink tubing that is thick with a sealant. The shrinkage was very good as is the durability. I used this for modifying the lighting on my motorcycles where I added some resisters. To hold them on the bike so I didn't have to drill holes, I used hose clamps to hold them against the frame. I slid the heat shrink onto the hose clamp for looks and added durability. I looked very good.

What I wanted . Good price.

Measured 13’3” packaged wrapped around cardboard sheet, the tube is stiff and has a sharp edge where it’s folded. Takes high heat to shrink, if covering long items work slowly to not trap air in the process. Trapped air expands and the tube will inflate like a bicycle tube when heated.

I ordered 3/8th inch tubing and when this arrived it looked way too big. In fact, it measures 1/2". I ordered 3/8ths inch because the stuff I have on hand does not shrink enough. However, when I shrank this, it goes down to less than a 1/4" OD. This is great stuff!! The adhesive seal is a great feature on heat shrink tubing because it prevents it from sliding on the wire and keeps out moisture and other contaminants. This is a better than average product and is a good value.

Good value. Use them to cove DYI pencil weights for fishing.

Excellent product! Shrinks well, really seals great, and it's tough.

This 5/8 inch (15.87 mm) heatshrink tubing arrived wrapped, flat on a piece of cardboard, in a vacuum sealed plastic pouch. It's marketed as a 3:1 heatshrink, which the Amazon page says 13/64 inch (calculated to be 5.15 mm), but I'm finding that it doesn't shrink down to this very easily. I had to apply a lot of heat.
