Is pipe thread stick the same a plumber’s putty?

You need the plumbers putty. The stick is for lubricating the threads on pipe. I prefer teflon tape over the stick though. Roll the plumbers putty into a “worm” and place it around the bottom of the flange and press in place. Tighten it up and then remove the putty that squishes out.

I don’t think so.

Pipe thread stick is a solid material used to seal the gap between the male and female threads of pipes and fittings. You scrape it on the threads like a crayon.

Plumber’s putty is more like a soft clay material used to fill gaps between porcelain sinks and plumbing fixtures such as faucets, spouts and drains. I think the putty has linseed oil to keep it pliable and from drying out.

Scoop out a wad of putty, roll it between your hands to make a rope, then mold on the sink at the drain location. Install the drain & popout, tighten the nut from below and the putty will squeeze out to fill the gap. Wipe away any excess putty and save it in the jar for another day. Smooth the putty and you’re done.
