3MTemflex Rubber Splicing Tape 2155, 3/4 in x 22 ft, Black, General Purpose Self-Fusing Electrical Insulating Tape, 1 Roll

If you are using an antenna and want water protection this is a must. You can find cheaper product but cannot beat 3m quality

Love this tape for a ton of uses. Good grip tapen good for making connections between two stubborn parts, great how it locks to itself and doesn't usually faulter. A regular player in my house, worth the cost.

Compared to others I have tried, this is the most uniform & consistent of material. It is also more expensive, so consider this top end. The first inch or two has a tape on one side; cut that off & the remaining roll is free & clear on both sides. BTW, that little bit of ‘tape’ is also the backer material between the layers (keeps it from sticking to itself), and if any is stubborn to remove, when you stretch the silicone tape, that material will separate. Obviously, stretch & press into itself to fuse. Water tight.

Before there was vinyl electrical tape, there was rubber tape, which made nice lumpy insulation on power cords, but has to be wrapped in a cloth tape ("friction tape") to protect it. I'm betting it still gets used for heavy-duty, industrial electrical connections. Meanwhile, if you just need to cover something, bicycle handlebars or a rotting brake handle hood, a slippery doorknob, a tool handle, this stuff is excellent. You stretch it while applying and wrap it in layers and it sticks to itself and stays like that. A good addition to a toolbox or kitchen junk drawer.

This is not tape as you think of tape. No sticky adhesive. It is stretchy rubber that fuses to itself when wrapped forming a solid piece of rubber. Once fused it will not unwrap but you have to make sure the loose end fuses. For extra protection and durability wrap over it with electrical tape. I use this mainly for my radio coax connectors and it really keeps the moisture out. Amazing stuff if you want a durable, long lasting water proof connection. Also great for tool handles.

This is good fusing tape and after years of reviewing Amazon products I've decided to stop giving so many 5-star reviews. This tape works great when stretched and adheres to itself well just like it should. It's thick and didn't break easily in the few times I've used it so far on my trailer. The only thing is that when hanging up in the shop, the tape doesn't stay stuck to the roll, so it might get dirt under the last inch or so. Otherwise it's great.

Holds great

There's not as many use cases for this type of tape as there are for something like gorrilla tape, but when you need this stuff, there's just nothing else like it, and 3M's version is very high quality. Once it's stretched and overlapped it becomes nothing short of a single piece of rubber.
