## Description

F4 Tape - Self-Fusing Silicone Tape MIL-SPEC 1" X 36' (Black) : desertcart.in: Industrial & Scientific

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.
Review: One of the Best Self Bonding Silicone tapes on the market. - 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.

## 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.

### ⭐⭐⭐⭐ So far so good...
*by A***L on 9 May 2024*

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.
