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.

Saved Senior from total disaster. Fellar gave me 20 4 lunch..x2 cost Absolutely positive he made it home and to shop across town for repair with no issues whatsoever. This tape is absolutely a miracle worker. keep in vehicle

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.

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.

Mechanical: speedboat throttle connection still good 6 years later. Copper Pipe & Rubber Hose: 3 years later. Still strong! No leakage or bulges. I failed to winterize a house spigot and a garden hose. Frost/freezing did it's thing and blew the lines. The KEY to having a successful pipe/hose repair is two fold: A) Not exceed max PSI B) PROPERLY applying tape. PROPERLY APPLYING TAPE: Don't just wrap it tight one time and expect it to work or claim that IT failed. If you don't wrap as follows, then YOU failed to apply it correctly. Applying it correctly is the best way to contain high psi as opposed to connecting two parts together - which can vary the wrapping process greatly depending on the parts being joined. For splits/punctures in Hose and Pipe (+/- 3/4") do the following: Step #1: Begin wrapping on solid, clean hose about 6" to one side of the split/leak. STRETCH wrap it towards, over, and past the split/puncture area another 3 or 4 inches and stop. Step #2: VERY CRITICAL STEP - "DOUBLE BACK" over your first layer of tape towards where you began wrapping. Stop about 3 or 4 inches beyond the split/puncture. You now have TWO (2) tight layers over the split location that extend 3-4" on either side. Step #3: Reverse direction again. Moving toward, over and beyond the split/puncture location. Continue warping about 6" on clean, solid hose. You should now have THREE (3) full layers covering the puncture site - not counting the additional 50% coverage layers created by overlapping each rotation. Step #4: Double wrap the very last roration or two in order to help secure the final loose end from unraveling. Success depends on a tightly stretched pressure on each wrap, proper 50% overlap on each wrap, and following the Left/Right/Left steps above. For extensive psi's, temperatures, large diameter hose, long gaping splits, or spiral punctures consider widening your application site and doubling back additional times as necessary in order to contain the leak and restore proper function. The repair doesn't need to be from one continuous roll of tape. Layering is what matters. It can be applied wet or dry. There's "Emergency Tape" (cheap) and "Emergency Self Fusing SILICONE Tape" (quality). Their performance is like night and day. F-4 Silicone Tape is the the higher quality good stuff. I've used both. FiberFix Repair Wrap is another repair tape that's a good "cast or splint" like material. It can be applied OVER Self Fusing Tape for added stiffness.

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

I saw a video on YouTube about this tape. At first, I was no, no way. I bought it anyway. Well, I will say this stuff works. I used it on my 100-foot-long garden house. It had a bubble forming, so I wrapped this stuff around it, and it is still holding. Even with all the heat Illinois has been having, this is a garden house sitting out in the yard in the sun. Works great.
