Tape sealants are simple to use, but like most things if not used correctly it can cause you stress and stress on the fittings. In this blog, we are going to go over the different tape sealants available and what the best applications are for each tape.
Polytetrafluoroethylene, is short formed to PTFE, for obvious reasons. PTFE is less likely to cause friction against other solids. Standard PTFE tape is mainly used for water system connections, either potable or non-potable as they are corrosion and acid resistant. Applications where the standard PTFE tape works best is in high pressure lines and used best with most chemicals. This makes it easy to ensure you are grabbing the correct tape for each application. Specialty PTFE tape is also much thicker than the standard tape and it has significantly higher density.
The white premium PTFE tape is good to be used for all industrial applications. There is no pigments or additives making it good to be used on all applications including water, oil and food processing. Mainly places where non-contamination standards are set pretty high. Just like the name implies, this PTFE tape is most commonly used by plumbers and pipe fitters. It is color coded pink to signify that this tape is a heavier duty tape than the standard white thread seal tape.
This PTFE tape is designed specifically for gas lines of all types, propane, butane lines and even natural gas. This yellow PTFE tape meets all gas company standards world wide and it seals threads quickly and easily.
You may need to use Teflon tape aka plumber's tape for this part, which is used to seal and lubricate threaded pipe joints. Not suitable for every shower head In that light, some shower heads are not that durable and therefore, the Teflon tape is not recommended to be used on them. Usually, if you have a plastic shower head , the Teflon tape could damage some parts or even create a hole inside a shower head pipe once you try to remove it.
If you're looking for electrical tape for insulation purposes, we recommend using standard black electrical tape. You may also prefer Teflon electrical tape for mechanical and automotive applications where a high level of heat resistance is required. Essentially, the only difference lies in the name. PTFE is the shortened name of the chemical polytetrafluoroethylene , and Teflon is the trade name of the same polymer.
Tape or dope should be used when the threads of a pipe are being used to create the seal. In a compression fitting, the ferrule is what creates the seal by deforming to the shape of the pipe. Similarly, some gas pipes use a flare fitting to make air-tight the connection.
How much thread seal tape should I use? Category: home and garden indoor environmental quality. You always want to wrap seal tape around threaded pipe fitting in a clockwise direction. In most cases for a new joint you should apply only two or three wraps of tape.
On older fitting where the threads may be damaged you may consider adding a few more wraps, but keep the number of warps to a minimum. What is the difference between red and blue Teflon tape? What can I use instead of Teflon tape? Will Teflon tape stop a leak? Should Teflon tape be used on PVC threads? Is pipe thread sealant better than Teflon tape? Can yellow Teflon tape be used for water? Is plumbers tape necessary?
Do you need to remove old plumbers tape? Can you use Teflon tape and thread sealant together? Can you use electrical tape for plumbing? Is Teflon tape necessary? You can find it in your local hardware store where it is usually sold in varying sizes, from small rolls to big spools. This makes PTFE tape a must-have for plumbers and anyone who does pipework jobs, such as irrigation contractors.
Every plumber worth his salt would have one of these tapes stocked in his toolkit. Interestingly enough, the manufacturer of Teflon, DuPont, has never made its product in tape form. All of these terms refer to the same product at the end of the day. Standard PTFE tape is quite versatile and is used to seal water, gas, and air from leaking through threaded connections, most effective on high-pressure lines. However, there are also specialty thread seal tapes geared towards a specific task or need.
To make choosing a specialty thread seal tape easier, they come colour-coded for the type of application each one caters to. Generally, however, specialty thread seal tapes are much denser and thicker than the standard version. White is the standard colour for thread sealant tapes and it is recommended for basic plumbing jobs.
It is still sturdy with all the features of PTFE: high resistance to most chemicals, high resistance to extreme temperatures and can tightly seal threaded pipe connections.
Colour-coded for water lines, pink thread sealants are used by pipe fitters and plumbers. As such, it is very heavy duty compared to the other standard type of tape. Yellow thread seal tape meets all gas company standards for gas lines of all types, be it butane, propane, or natural gas.
Green thread seal tapes are required for oxygen applications, as it is grease-free yet does not allow fires to start. Grey thread seal tape has a high density rating and is nearly double the thickness of standard thread seal tapes, making it ideal for taping up stainless steel threads, preventing seizing and galling. In short, thread seal tape is best used to seal up most threaded connections. However, if said connection has a rubber seal or gasket, you also do not need thread seal tape.
While thread seal tape is not difficult to use, it is not as simple as slapping on some good old duct tape and calling it a day. The way it is applied is vitally important, not only because incorrect application will fail to keep your connections and pipes watertight, but taking off wrongly applied thread seal tape so you can re-apply it can be a major pain.
