Bond It F4 Emergency Self-Fusing Silicone Tape, Repair Plumbing Pipe & Radiator Hose Leak, Electrical Insulation, Permanent Bonding, Waterproof, 1" x 36' x 20mil, Red

I have used this product for years and love it. Do not try to use it for some high pressure application like an air hose, but for many other applications, it has worked great. I've used it for building cables, electrical harnesses, etc. I've also used it to create a seal on landscaping irrigation tubing and some sprinkler drip systems.

Self fusing tape is not sticky tape. You have to stretch it a lot so the wraps pull nice and tight and fuse to themselves. I use this type of tape for non-pressure waterproofing, smoothing out hose clamp wire & the like so it doesn't snag, building strain reliefs, and emergency (and temporary) pressure patches. I once patched a radiator line on a vehicle with silicone tape - expecting it to fail in minutes or an hour. Lasted around a month (I left it on to find out). Easily long enough to get by while I ordered the replacement part. But this stuff is not duct tape or gaffer tape. It has different uses than sticky tape.

I have used a few different brands of this type of tape over the years. I use it for a wide range of things. From electronics and wiring to waterproofing and sealing and even arts and crafts and I love it. This brand it quite sturdy and thick, stretches out and bonds exceptionally and does not peel back at the end over time like many other brands do. Its plastic backing it also actually stuck to it unlike many other brands I have used where it is just a loose layer that fall off easily when applying long strips or directly off the roll. Just remember, it attracts dust and particulate like a magnet attracts metal filings! And the cleaner it is the better it bonds, so clean your work area if possible and wash your hands before applying it. The one feature this brand has that brings it to the forefront though is the thin blue line going down the middle of it. This makes it a snap to line up and apply evenly, allowing you to get the most use out of every piece. Very handy. And if you do not want or need it you can simply put that side on the inside as the other side is blank. It is available in a bunch of colors, even clear, and the amount you get the price? VERY good deal for a very good product. Kudos to the manufacturer I would recommend this product without hesitation and will be purchasing it for as long as it is being made.

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.

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.

Excellent product and the the quality is Air Force grade wrap that sticks and seals to its self and is perfect for wrapping spliced wiring or using it to stop water leaking in lines and shut off valves. This product saves you a lot of time and very easy to use.

Just wasted 17$. Not holding the water leakage. Tried several times with different tension - same result.

I never want to be without this in my shop I repaired my Festool Rotec coiled dust hose with this stuff. Amazing holding strength.
