Review on Gasoila Virgin Density Thread Length: Optimizing Performance and Durability by Rob Madden

This is a high quality Teflon tape. I use this for several items. However, I am a little disappointed as the tape is listed as 1/2" wide and the label on the box says 1/2" wide when it is almost 7/8" wide. This makes installation on smaller fittings more difficult. I had a reel that size and ordered 1/2 inch specifically for certain fittings. I ended up going to the hardware store to get the correct tape as it turns out some people around the world don't seem to know the difference between 1/2" and 7/8".
