Teflon tape, also known as PTFE tape, is an essential plumbing product best known for its ability to guarantee perfectly sealed fittings and connections. Whether used to prevent leaks or ensure a long-lasting installation, understanding its use and advantages is of utmost importance for all wannabe or professional plumbers. 

What Is Teflon Tape (PTFE Thread Seal)?

Teflon tape, often referred to as plumber’s tape or PTFE tape (polytetrafluoroethylene), is a white tape used to seal thread fittings. It’s especially appealing on account of its anti-adhesive and waterproof properties, allowing one to seal piping and ductwork against natural gas or water leaks effectively. It’s commonly used on PVC or metal plumbing fittings. 

What Are the Benefits of Using Plumber’s Tape?

Quick and Easy to Use

Plumber’s tape is pretty straightforward to use and apply, even for plumbing task novices. Simply wrap the tape around the male thread fitting or pipe before screwing it in place, ensuring for a quick and effective installation. 

High-Quality Seal and Leak-Proof

Teflon tape is perfectly suited to pipework threads, filling in the gaps and preventing water from filtering through, which makes for a reliable solution to prevent potential leaks, even when exposed to intense pressure.

Withstands Corrosion and Chemical Products

Courtesy of its chemical properties, Teflon tape can withstand corrosion and harmful chemical products, which, in turn, extends the service life of the fittings.

Wide Range of Operating Temperatures

Plumber’s tape can be used in conjunction with a wide range of temperatures, which makes it adaptable to various weather conditions, from very low temperatures to very high ones. 

Reusable and Does Not Deteriorate Over Time

Teflon tape doesn’t degrade easily over time, which means the fittings can be reused without fearing potential leaks.

What Are the Downsides of Teflon Tape?

Higher Price Tag Than Alternatives

Teflon tape can be a bit more expensive compared to other sealing options, such as pastes and oakum (tarred fibres), which may result in pricey plumbing projects.

Not Suitable for Every Fitting Type

Plumber’s tape isn’t suited to all types of fittings, most notably those with a loose nut or requiring extra-tight clamping.

Can Restrict Water Flow

Improper wrapping or excess application of the tape can obstruct water flow, resulting in drainage problems.

Teflon Tape: Types, Pricing, and Sizing

There are several different types of Teflon tape used for plumbing-related work, each designed with a specific use:

  • White Teflon tape: Basic thread seal tape, 0.074 mm thick, and ideal for all common plumbing fittings. Cost: about $1.50 for a 0.5 in x 12 m roll. 

  • Pink Teflon tape: Thicker (0.2 mm) and denser than standard Teflon tape, is extremely heavy-duty, which makes for a better seal. Cost: about $3.50 for a 0.5 in x 12 m roll.

  • Premium high-density tape: 0.1 mm thick, recommended for damaged fittings or renovations. Cost: about $2.75 for a 0.5 in x 12 m roll.

*PTFE tape also comes in green, yellow, and grey, each indicating a specific use.

Sealing Threaded Plumbing Fittings

Teflon tape is perfect for sealing threaded fittings, ensuring a leak-proof seal.

Faucet, Valve, and Pipe Fittings

It’s commonly used with faucets, valves, and pipes to prevent leaks and ensure a watertight connection. 

Kitchen & Bathroom Sinks and Toilet Fittings

Teflon tape is also used to seal bathroom and kitchen sink fittings as well as toilet fittings, where leak-proof installations are mandatory. 

Minor Leak Repair

Cracked or Worn Joints

Teflon is used to repair cracked or worn joints, extending the fitting’s service life.

Damaged Threads

It’s also used effectively to seal damaged threads, ensuring a watertight hold despite imperfections.

Applying Plumbing Pipe Tape: How to Wrap It

In which direction should polytetrafluoroethylene tape be wrapped?

The thread seal tape should always be wrapped in a clockwise direction around the male thread fitting to prevent it from peeling off when the fitting is unscrewed.

How many times should it be wrapped around?

The number of wraps depends on the fitting’s width—typically, 3 to 5 wraps for small fittings and up to 10 for wider fittings.
