Most people don’t know that less than 10% of PTFE thread seal tape used in the United States is actually made in the United States. And although there are specifications for imported tape, the truth is the thickness and density of your foreign-made tape is probably much less than it claims to be. In fact, imported tapes often contain less than half the PTFE required by the certification they claim to meet. Even more troubling, you’ll be hard pressed to find a single American made tape on most retail store shelves.

PTFE Thread Sealant Tape Density

So if you’re like us, you might take a micrometer down to your local hardware store to see for yourself if the tapes they offer meet the specs.

But we’ll save you the trouble. We did the thickness test, and none of them passed. Shocked? We were, too.

These specifications exist for a reason. The quality of your tape matters, and choosing TaegaSeal tape improves the reliability of your work, ensures that it lasts longer, and even prolongs the life of your pipes and threaded joints.
