How To Use Thread Tape On Compression Fittings

Threaded fittings are commonly used in plumbing to join two pieces of metal together. A compression fitting is a type of threaded fitting that uses a nut and a ring to compress the metal tubing against the fitting to create a water-tight seal. In order to use a compression fitting, the tubing must be clean and free of any burrs or nicks. The threads on the tubing must also be lubricated with thread tape or pipe dope to ensure a water-tight seal.

How To Use Thread Tape On Compression Fittings

Thread tape is a type of sealant used on compression fittings. It is a Teflon tape that is wound around the threads of the fitting before it is tightened. This forms a seal between the threads and prevents leaks.

  • Replace the compression nut on the compression fitting and tighten with the pipe wrench
  • Using a pipe wrench, remove compression nut from the compression fitting
  • Thread the pipe tape clockwise around the threads of the compression nut

-When using thread tape on compression fittings, make sure the tape is wrapped tightly around the threads. -The tape should also be applied in the direction of the threads. -If done correctly, the tape will help prevent leaks and ensure a secure connection between the fittings and pipe.


Frequently Asked Questions

Do You Need Ptfe Tape On Compression Joints?

No, you don’t need PTFE tape on compression joints. Compression fittings are designed to be watertight without any tape or sealant.

Do You Use Teflon Tape On Brass Compression Fittings?

I use Teflon tape on brass compression fittings if I am not using a lubricant. If I am using a lubricant, then I do not use Teflon tape.

Do You Use Pipe Thread On Compression Fittings?

Pipe thread is not used on compression fittings. Pipe thread is a tapered thread that is used to join two pieces of pipe together. Compression fittings are a type of fitting that uses an O-ring to create a seal.


In Closing

Thread tape is used to help the compression fittings create a watertight seal. The tape is wrapped around the threads of the fitting and the threads of the pipe. When the fittings are tightened, the tape helps to keep the water from leaking out.
