That's all there is to it. Leaks are common, and small ones are often hard to find. Then get a hand quantifying each leak and choosing cost-effective ways to tighten up. In our Swagelok Tube Fitting Safety Seminar, our Swagelok certified trainers will show you how to properly apply PTFE thread sealant and other sealants and lubricants, and then ask you to do it yourself under their watchful eye.
You will also learn about pipe fittings, tubing handling, how to correctly install a Swagelok tube fitting, and more. Your fluid systems can't fail—and they can't leak. That's why Swagelok Northern California offers mission critical solutions for the petrochem, semi, power, and oil and gas industries around the Bay Area and into NW Nevada.
We manufacture and assemble reliable, customizable components that get the job done. Improper gas seals may lead to poisoning, fire, or other hazards. If you have little to no experience in working with water or gas lines, hire a professional to avoid personal injury and property damage. Do so before you begin to put everything back in place so you still have quick and easy access to the pipes in the event of a leak.
Follow color-coding. Always use yellow Teflon tape for gas-lines, since this yellow tape is specifically for that purpose. For waterlines, use pink tape for best results.
For oxygen lines, only use green tape. White tape is cheaper for a reason. Its low density often necessitates using more tape to achieve the same tight seal as a high-density product. It is also more prone to tearing, with stray bits ending up inside the pipe and potentially causing blockage.
Read the directions. Check if the instructions recommend covering the threads with a specific number of layers. Do not exceed the recommended number, since this may cause a loose seal when the extra tape bunches up during screwing. Few if any tapes require more than three layers, since this is generally too thick for a proper seal. Apply tape to correct minor flaws only. Do not connect pipes with missing or broken threads.
Buy a new pipe instead, or have the original re-threaded. Install a dielectric union to connect pipes made of different metals. Expect pipes made of different metals to corrode over time if they are screwed together directly. Do not trust Teflon tape to act as an adequate barrier between the two materials. If you are connecting two different kinds of pipes, purchase a dielectric union to join them without bringing them into direct contact.
Use Teflon tape or other sealants on these to correct the micro-flaws caused by mass production. Include your email address to get a message when this question is answered.

Step 4: How many times the thread seal tape will go around the pipe depends on the thickness of the tape, but for the standard variety, about five or six wraps should be enough for the job. Step 5: When done, simply grip the tape tight and give it a strong tug. Simply smooth out the remaining loose tape onto your pipe, and you are done. While using thread seal tape is great in most cases, unfortunately there are some occasions where it is not the ideal tool for the job.
Some pipes have wide threads, which causes water to dribble through. In other instances, the opposite problem can exist, where the pipe will not give you enough room to properly apply the tape. Also, the threads of the pipe you are trying to seal may have suffered some damage or wear and tear, which would make it very difficult for thread seal tape to create an air- or water-tight seal.
In situations like these, you will need to look for suitable alternatives to thread seal tape to get the job done. It usually comes with a small brush to apply the compound with. Like thread seal tape, there is a general use or universal variant of a pipe joint compound; but there are also types that can only be used for a specific type of pipe, such as metal or plastic. Some pipe joint compounds may also not be suitable to use on water or gas, for example.
Make sure you read the directions on the product carefully. Some plumbers and other workers use both these products in the same application, adding a thin coat of a pipe joint compound over the thread seal tape to insure a watertight or airtight seal. Another alternative to thread seal tape is Valve packing, which is another form of Teflon. Tape sealants are found all over the plumbing world. They are used in many Industries as there are different tape sealants for specific applications.
If you need tape specifically for stainless fittings, there's a tape for that. 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.
