Proper Installation of Dry Seal Pipe Plugs
The following is a general guideline for the proper installation of NPT Pipe Plugs. It would be to your advantage to consult with your piping or fitting manufacturer regarding their suggested Turns From Finger Tight.
- FTHT (Fit to Hand Tight) is the threaded assembly screwed together hand-tight but without any sealant applied to the threads.
- TFFT (Turns From Finger Tight) or TPFT (Turns Past Finger Tight) is the number of complete rotations of the fitting recommended after making the connection finger tight.
Installing NPT threaded components
These are the steps commonly used to get a leakproof seal when installing NPT threaded components in a hole that has been taper reamed and tapped:
- Check that the male and female threads are clean and free from dirt, burs and/or nicks.
- Apply an appropriate sealant to the male threads.
- Tighten the fitting by hand until it is finger tight.
- Use a wrench to tighten the threaded joint up to the wrench-tight thread engagement recommendation.
- If you are installing a shaped fitting, wrench tighten to the minimum recommended turns and then tighten as needed to get the desired orientation.
