Frequently Asked Questions
Q. "Can PTFE thread sealing tape be used in all applications?"
A. Per Wikipedia: "Overuse or misapplication of thread tape may be a hazard. Excess application of PTFE tape can prevent mating threads from fully engaging, reducing the shear point of the threads. Combining thread-seal tape with a pipe dope compound can also overload threads. Also, internal overhangs of loose material may constrict a joint or slough off and form a foreign body that could jam a valve seat.. Therefore, use of PTFE tape as a thread sealant is generally not considered appropriate in fluid power (hydraulic) systems.
Q. "Any tips on using PTFE thread sealing tape?"
A. First, with plastics try to avoid using a female threaded adapter because it is very easy to split when over tightened (with thread sealing tape it is easy to over tighten). Wrap your PTFE thread sealing tape "with" the treads - that is... pipe in left hand, PTFE thread sealing tape right, roll on clock-wise. Generally at least 3 times. Sometimes adding thin coating of a good quality thread compound on top of the PTFE thread sealing tape helps seal joints even better. Caution: Do not over apply, excessive tape may actually weaken the connection.
Q. "I don't see where you offer Teflon® tape. Where do you have it listed?"
A. That's because it's not available anywhere as the owners (DuPont) of the name "Teflon®" no longer make it. If any supplier offers to sell you "Teflon® Tape" when you need thread sealing tape they are mistaken/wrong in using the word "Teflon®" or (hopefully not) are intentionally trying to mislead you as you should be aware that no plumber (thread sealing) tape is authorized by DuPont to be sold as "Teflon® Tape." Therefore, we offer PTFE thread sealing tape instead. PTFE is the abbreviation for the chemical composition poly-tetra-fluoro-ethylene. PTFE is a heat resistant, non-sticking, chemical and corrosion resistant film cut into these widths and lengths for the purpose of sealing pipe threads. The tape we offer might not contain any actual DuPont brand products in its composition.
Q. "How many wraps of Pipe wrap tape do I need to use for my buried gas pipe?"
A. Most codes require 40 mil protection and so, depending on the thickness of your tape, you will need to apply several layers of tape to the entire length of your pipe that is going to be buried. We do recommend that you check your local codes to make sure you have the most up-to-date information on codes. Also, make sure that you wrap any place where the epoxy has been chipped by the pipe vice or pipe wrench as this will corrode quickly if you don't.
