Trick of the Trade: Applying Teflon Tape

Trick of the Trade: Applying Teflon Tape

IMG_1685-300x225

There is a reason that “non-handy” people sometimes struggle so awkwardly with mechanical tasks. It’s because there is an entire playbook of simple, untold habits that so-called “handy” people have picked up. People like carpenters, plumbers, handymen, electricians, auto body workers, welding technicians – people who work with their hands for a living (or a hobby!). If you tinker with things enough, especially from a young age, you get a feel for how to do things that it’s hard to learn any other way.

This leads to a communication impasse at times. A mechanically-minded person will delegate what they consider a straightforward task. But there are two problems – one, the engineering mindset may have left out some logical steps along the way, and expect you to fill in the gaps. For instance, “Go plug in an extension cord for me.” What you discover is that a) the extension cord lying right there is too short, and you will need to go get the other longer one from the garage. Second, there are no plugs nearby so you will have to run it through the window. And third, the breaker is tripped, so you will need to reset the switch in order for the power plug to work.

The second problem with delegating is that even AFTER the task is done, the handy person may come back and determine it has been done incorrectly. Yes, you may have attached the extension cord, but did you knot the two cords together so that, if pulled, they won’t dettach?

No? Then you did it incorrectly. Because the handy person doing the delegating may not specify all the untold habits that may come into play. I can remember clearly in my own household, “But you didn’t SAY that,” my mother will cry frustratedly.

These little tricks of the trade are also why experienced mechanics or carpenters or construction workers can almost instantly spot a novice’s work: the little things are off.

So, in this spirit, I’d like to share a few useful tricks, although I can’t take any credit for them: I’ve learned them from the mechanics in my own life. Today, how to apply Teflon tape.

Teflon tape
Teflon tape is applied to threaded fittings so that liquid or air does not leak out of the threads. It’s a white tape, simply wrapped around the fitting. Not hard, right?

Teflon tape and fitting
But there’s a trick. You want to wrap that tape so that when you screw in the fitting, the tape doesn’t UN-wrap itself. Think about it: if you screw in a fitting “righty tighty, lefty loosey” you want the tape to be wrapped in the same direction so that it tightens on the threads as you tighten the fitting.
But it’s hard to think in three dimensions like that while you are standing there with a roll in your hand. So I learned to do it the same way every time. I’m left handed, so I hold the fitting in my left hand, threads out, thumb on top.
Hold fitting in left hand, threads out, thumb on top
Hold Teflon tape in right hand, twist fitting to the left as you wrap the tape.
Start tape holding in right hand, end under left thumb
Twist fitting to the right as you unroll tape
Following that procedure, the tape comes out wrapped the correct way every time. If you are right handed, adjust to make it work for you. You can use trial and error to figure it out the first time, since no matter what configuration you hold things, in the end your only two end results are tape wrapped counter- or clock-wise. The key is, once you find a way that works, stick with it!

Leaking sprinkler systems can cause tens of thousands of dollars in damage to ceilings, floors, furnishing and other valuables. Preventing these leaks is not an option for installers, it is a requirement. The metal pipe connections in sprinkler systems can be sealed with PTFE tape, pipe dope or anaerobic sealant; the choice of products is dependent on the application.

Sprinkler systems that are composed of metal pipe have two primary causes for leaks. The leaks in the connections of metal pipe as well as the pin hole leaks in the welds. Pin hole leaks can be prevented or eliminated by heating the pipe and coating with an anaerobic weld sealant.

Preventing leaks in the connections and fittings of the pipe can be done with PTFE tape, pipe dope or anaerobic sealant.

PTFE Tape

PTFE tape can seal connections, if the pipe is not directional. Tightening of the pipe must be done to the proper torque. If the pipe is over tightened or must be loosened to change the direction of the pipe the seal is no longer In other words if it is at the user discretion when to stop tightening. PTFE tape is not recommended on nicked or damaged threads.

Pipe Dope

Pipe Dope, a solvent based adhesive, remains a paste. It provides a good seal but does not prevent loosening due to vibration or stress. Pipes that change temperature frequently or are near equipment or other sources of vibration may loosen over time.

Anaerobic Sealant

Anaerobic sealants cure to form a plastic seal. They cure only when in contact with metal and removed from oxygen. This makes them easy to work with and clean up. Many contain PTFE which eases assembly.

Anaerobic pipe sealants provide an instant seal of up to 1000psi and when cured can exceed the burst rating of the pipe. The cure does not happen instantly so if pipes must be realigned within the system to square off the lines, readjusting will not disrupt the seal. The high viscosity material provides seals on nicked or damaged threads.

Should it ever be necessary to disassemble a sprinkler system sealed with anaerobic sealants normal hand tools will do the job. Anaerobic sealants provide inherent corrosion prevention so there are no rusted connections to deal with.
Traditional Anaerobic sealants should not be used on CPVC (plastic) pipe, however, anaerobic pipe sealants have been developed for use on metal pipe work in systems that may also contain CPVC.

Thread seal tape (also known as PTFE tape or plumber’s tape) is polytetrafluoroethylene (PTFE) film for use in sealing pipe threads. The tape is sold cut to specific widths and wound on a spool, making it easy to wind around pipe threads. It is also known by the genericised trade-name Teflon tape; while Teflon is in fact identical to PTFE, DuPont (the trade-mark holders) consider this usage incorrect, especially as they no longer manufacture Teflon in tape form.Thread seal tape lubricates allowing for a deeper seating of the threads, and it helps prevent the threads from seizing when being unscrewed.The tape also works as a deformable filler and thread lubricant, helping to seal the joint without hardening or making it more difficult to tighten,and instead making it easier to tighten.

Typically the tape is wrapped around a pipe’s thread three times before it is screwed into place. It is commonly used commercially in applications including pressurized water systems, central heating systems, and air compression equipment.

Thread tape is appropriate for use on tapered threads, where the sealing force is a wedge action. Parallel threads may not seal effectively with or without tape, as they are intended to be sealed by a gasket.

Thread sealing tape is almost entirely applied by hand, although at least one machine is available for production wrapping of fittings.

PTFE tape is also commonly used in the stretching of body piercings, through a process known as taping, because it is inert and safe for this use. The wearer wraps layers of the tape around a plug, slowly increasing the size and thus slowly increasing the size (gauge) of the piercing.

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.

It is considered one of the most essential household items that help to stick almost everything in your home. But the use of it is far more wide and varied than we know. In fact there is a wide variety of it that are used for various purposes in addition to sticking pages or wrapping gifts.

The Different Varieties of Adhesive Tapes

The first tape was invented in the year 1845 by Dr.Horace and ever since then there has been a sequence of inventions of different varieties of tapes used for bonding purposes.

These tapes are used mainly for fixing broken things like toys, plastics, and so forth. It is also used by children for craft purposes. Available in different vibrant colors, these are often used by children to highlight pages in their books. But the uses of these are myriad. These can also be used on clothes and glasses.

The different varieties of tapes include the double sided adhesive tape, the duct tape, the masking tape, foam tape, pressure sensitive tape, ptfe glass adhesive tape and so forth.

Mirror tapes with different colors and designs are used for decoration purposes, wrapping gifts and for other multiple purposes. The box sealing tapes are used for packaging purposes. With the double sided tapes you can easily join two things back to back unlike the single sided tapes.

Some Useful Varieties among these Tapes

Another variety of this useful tape is the electrical tape which is used to bind electric wires. Since it is made of vinyl, it does not conduct electricity and is considered a safety measure.

The surgical tape is yet another variety of adhesive tape that is used to stick the dressings on the wound. The duct tapes are used mainly for industrial purposes like sealing ducts and pipe leaks. It is also used for construction purposes like sealing windows and so forth.

The heat activated it is used to bond materials such as felt. It is mainly useful for sticking rough surfaces.

The gaffer tape, which is also known as PCL tape, is another variety of tape which is used in the entertainment industry for sticking the cables. It is also used for repairing carpets and to create a waterproof seal. It is a useful accessory found in every tool box and is used for multiple purposes. The gaffer adhesive tape is also quite effective in sticking polythene tents used during construction purposes.

The reflective tapes are used on roads to increase the visibility during bad weather conditions and at night.

In addition to all the above varieties there are printed tapes too which can be used to display important messages like handle with care, do not bend and so forth. These tapes are used on packages and cartons.

The use of it is not limited to just wrapping gifts or sticking pictures. It has multifaceted purposes with the huge range of varieties available. Most of these tapes can be bought from online stores listed in the b2b directories.
