Teflon tape, also known as thread sealing tape or PTFE tape, is a thin, white, non-sticky tape that is used to seal pipe threads and prevent leaks. It is made of polytetrafluoroethylene (PTFE), a synthetic polymer that has a very low coefficient of friction and excellent resistance to heat, chemicals, and corrosion. Teflon tape is widely used in plumbing, heating, air conditioning, and gas systems, as well as in marine applications. In this article, we will explain why Teflon tape is essential for boaters and mariners, how to use it properly, and where to buy it.

Why Use Teflon Tape for Marine Applications?

Teflon tape commonly used has many advantages over other types of thread sealants, such as pipe dope, silicone, or hemp. Here are some of the benefits of using Teflon tape for marine applications:
$#149; It is easy to apply and remove, even if exposed to high temperature, without leaving any residue or mess.
$#149; It creates a tight and reliable seal that can withstand high pressure, temperature, and vibration.
$#149; It prevents corrosion and galvanic action between different metals, such as brass and stainless steel.
$#149; It is compatible with most fluids and gases, including water, oil, fuel, air, and oxygen.
$#149; It is inexpensive and long-lasting, as it does not harden, shrink, or deteriorate over time.

How to Use Teflon Tape Correctly?

Teflon tape is simple to use, but there are some tips and tricks to ensure a good seal and avoid problems. Here are some of the best practices for using Teflon tape:
$#149; Choose the right type and size of Teflon plumber tape for your application. For example, use yellow Teflon tape for gas lines, pink Teflon tape for water lines, and green Teflon tape for oxygen lines. Also, use thicker Teflon tape for larger pipe threads and thinner Teflon tape for smaller pipe threads and ptfe thread.
$#149; Clean and inspect the pipe threads before applying Teflon tape. Make sure there are no dirt, grease, rust, or damage on the threads that could affect the seal.
$#149; Wrap the Teflon tape around the male threads in the same direction as the thread. Start from the end of the mating threads and work your way towards the base, overlapping the tape by about 50%. Use enough Teflon tape to cover the entire thread, but not too much that it bulges out or interferes with the fitting. Usually, 3 to 5 wraps are sufficient, depending on the size and quality of the tape and the thread.
$#149; Cut or tear off the excess Teflon tape and press it firmly onto the thread. Do not leave any loose ends or gaps that could cause leaks or clogs.
$#149; Screw the fitting onto the pipe and tighten it by hand, then use a wrench to give it a final turn. Do not over-tighten the fitting, as this could damage the thread or the seal. If the fitting leaks, try to tighten it a bit more, or remove it and reapply Teflon tape.

Where to Buy Teflon Tape?

Teflon tape is widely available at most hardware stores, plumbing supply shops, and online retailers. However, not all Teflon tapes are created equal. Some are of poor quality and may not seal properly, or may contain harmful substances that could contaminate your system. Therefore, it is important to buy Teflon tape from a reputable and trusted source, such as Fisheries Supply. Fisheries Supply is a leading supplier of marine products and accessories, with decades of experience and expertise.
