American Made Thread Sealant and its Proper Application

Before utilizing any PTFE thread sealant, customers should understand that there are not only a wide variety of applications for this product, but also understand there are distinct quality, availability, and application differences between foreign and American made PTFE thread sealants. People who use PTFE thread sealant, a product also know as plumbers’s tape or pipe tape, sometimes falsely believe that this product is only appropriately utilized in plumbing applications. In actuality, PTFE thread sealant is utilized for a multitude of applications. These applications include automotive, plumbing, and for use in joints made of metal or plastic.

Another common misconception is that all thread sealant tape, whether foreign or domestic, is of equal quality they are not. Furthermore, consumers often believe that few of these products are actually manufactured in the United States. In fact, there are two primary United States based manufacturers of PTFE thread sealant tape; one manufacturer is located in Texas and the other, TFCO, is located in La Porte, Indiana. Unfortunately, this superior quality American made tape is not available in large chain-based retail stores; therefore, obtaining superior quality American made thread sealant may require slightly more effort. The extra effort used in acquiring this tape is worthwhile because of the exceptional performance of these products.

TFCO thread sealant tapes are manufactured through a meticulous process in Northwest Indiana. The manufacturing process begins with virgin PTFE (Polytetrafluoroethylene) resin and ends with a superior quality thread sealant tape product. According to our data, no other US manufacturer Produces and distributes a larger quantity of thread sealant tape per year than TFCO.

4. Wrap the male threads with 2 to 4 layers of wrap, depending on the size of the thread. With larger diameter threads, users should use more layers of the product. Always wrap the threads in a clockwise direction. This direction is extremely important to prevent the female threads from pushing the PTFE out of the joint during the assembly process.
