Review: Self Fusing Tape Works GREAT on Rubber & Copper Tubing/Hose if used right! Here's how... - 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.
Review: A 'dream' product! - 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.

## Features

## Questions & Answers

**Q: sticky?**
A: This tape is NOT sticky, really, it's not meant to be. The tape works by fusion. Within seconds, the tape will fuse to itself. This tape has great use in taping around objects, rather than other usages of like duct tape or scotch tape. Figure this, i just soldered an 8 gauge wire to another 8 gauge. Now, I use the F4 tape to tape it up (and insulates it).How you can do it is:Hold on end and wrap around the wire until it comes back to the beginning. Pinch that for 2 seconds to secure it. Now with the extra, unfused, tape. Pull tight and wrap around the exposed wire until completely covered. If not enough was cut, cut more, press the new tape onto tape on the wire (it fuses) and continue. I use this strictly for electronics, but i'm sure it has other uses.

**Q: Does this tape meet mil-i-46852 type ii**
A: Our F4 Tape significantly exceeds the specifications as described in CID A-A-59163 (which superceedes MIL-I-46862).

**Q: What's the maximum temp this tape will take?**
A: F4 Tape resists 500F degrees (260C).

**Q: Can this seal a small split in a superconducting super collider?**
A: The Superconducting Super Collider proposed by the University of Texas Austin was cancelled in 1993 due to budget problems. 

With that being said, if you are talking about another Collider of similar ilk, and the split was less than and inch wide, the answer would be a resounding “probably not.”

I hope this helps, and have a great day.

### ⭐⭐⭐⭐⭐ For more extreme applications, it’s much better than duct tape but takes practice to use correctly
*by K***T on December 28, 2019*

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.
