When I first started working with pipe fittings, I learned that NPT stands for National Pipe Tapered. This means that the threads on the pipe plug are designed to create a tight seal as they are screwed into a fitting.

I’ve learned that installing a 1 1/4 NPT pipe plug is relatively straightforward. I usually clean the threads on both the plug and the fitting before installation. Applying thread sealant or Teflon tape can help create a better seal. I take care not to overtighten the plug, as this can damage the threads or the plug itself.
