I used this for a barrel extension for a firearm, it is very thick, durable, and easy to use, especially at high temperatures.Overall it functions great, keeps the extension screwed on even with lots of vibration, and is a great value for money.

Teflon tape is invaluable for lubricating and sealing threads. This is a thicker-than-normal tape that is very good for gas lines. It is high quality, I would buy it again.

Looked high and low for some pipe thread dope for propane fittings. I couldn't find any so I settled on this tape specially designed for gas fittings. I'm happy to say that it works just fine.

It seems that we always run out of this when we are working on stuff around the house and this 10 pack is a great way to avoid the problem. This tape is fairly thick and avoids the problem with some types that is super thin. The tape is thick enough to do the job and it stretches and self-adheres well. I will not need some for a while but I would buy this again.

Each roll is plenty long and works well for sealing threaded connections in plumbing, gas lines, and other projects. The tape is easy to apply and provides a good seal. For the price, you get more than enough to last a while.

I ordered 10 of these as the other brands are so thin and cheap and always frustrates me that I throw it away as it becomes to messy . I like the thickness & quality of this brand.

Good, thick tape but more difficult to work with than standard teflon tape. I used it with an AC pump and manifold and it prevented any air leaks.

I used this to install propane lines to the dryer. I wrapped the threaded ends, in the direction of how it screws on, 4 times. If you don’t the tape will bunch up as you attach it, and make an improper seal. I was surprised according to the directions, you do not wrap the part with flanged ends. FOLLOWING DIRECTIONS is so important! I was just about to make a mistake!

I purchased this to use with the Quickjack BL-5000SLX. That unit came with some liquid thread sealant which did little to stop the leaks. I used this on every fitting and after I was done working on my car, there were no more leaks.I found you need very little of this to work properly. At first I was putting too much on the threads and had to shorten it. I found about two wraps around the thread to work best. And of course wrap the tape around the threads so as you tighten the fitting it works with the motion and not against it. I.e. as you tighten it does not try yo unravel the thread.So all in all this does what it is supposed to do for hydraulic fluids instead of plumbing tape which is made for water.
