Bond It F4 Emergency Self-Fusing Silicone Tape, Repair Plumbing Pipe & Radiat...

Works on anything. Used it on my power steering hose that was leaking profusely. I use it on electrical wire. Truly is self-fusing, and it couldn't care less about dirt or oils. Once finished, it's like you just made a whole, tight, and solid rubber coat/tube. The blue line helps wrap tightly. Stretches wonderfully. Great for mechanics and technicians. Really a 'dream' product. Waterproof. Sticky. Designed with functionality in mind! Expensive, yes... but not really for what it is.

I have used this before and have repeated the purchase. There are generic versions but this version is superior. It worked well as electrical tape, repaired a plumbing issue, and after cooling the vehicle used ( an entire spool ) for TEMPORARY repair of a radiator hose.

That is the greatest strongest tape ever!

Note, I'm not using this product for any pipes are under any pressure. Please ensure you understand this context when considering this review. I have am using this product on my waste pipes on my RV/Trailer. Being exposed to the outside the adhesive on the pipe couplings started to dry out and leak. With a little alcohol to clean the pipes, I used it to wrap each of the adhesive points to prevent them drying out. Installation was very simple, but you do have to read the directions for optimal use. Because I was using this in a non-pressurized application, it was not necessary for me to stretch the product and wrap so tightly. Still, it was easy to apply. The product does adhere to itself meaning it does not require additional glues or the like. Lastly, it should be noted under demanding usages, it suggested you wrap the affected areas twice in one direction and then the other. Be mindful of this to ensure you have the appropriate amount of product for your repair. Overall, easy to use, works, and reasonably priced. I would recommend.

I have used this tape for a variety of projects that it was probably overkill for using. For example, the bar grip for my kids’ trampoline that the 2 year old started to bite chunks of foam off. However, I wanted to give one example that I think was on the more extreme end of things. I was driving home after a day-long meeting and noticed something hanging down on my car. I bent over and saw it was the muffler strap, argh! I stopped at my mechanic and they were too busy until later in the week and the auto parts store wouldn’t have it in until the next day. I needed to be at work the next day, so not driving my car wasn’t an option. So, I decided to give this tape a chance to hold my muffler in place. It worked like a champ even with the hot temperature and vibration it was experiencing. I had to cut it off with a knife when I replaced the muffler strap 2 days later. It was not melted or pitted from road grit at all. I probably used half a roll to be on the safe side, which was 4-5 times around the muffler and frame. There is an art to using this tape correctly. It needs to be pulled and layered onto itself. You can touch it to any other materials and it won’t stick, but once it touches itself you aren’t getting it apart so beware. I am usually prepared to use extra tape than I think because it does get stuck to itself, especially when you are wrapping it in a tight space (like under a car). It’s expensive, but works better than duct tape for a lot of things.

This Tape has been around since the Viet Nam War. Used extensively by the USAF to make Quick Fixes on Aircraft that came back damaged from a Mission. Damn GOOD TAPE. Once bonded to itself you cannot get it off, except with a Razor Knife.

The material may be MIL spec, but the thickness isn't. This is half the thickness of other F4 tape I have used.

Excellent product. Used to repair a damaged power steering hose.
