Product Questions & Answers

got a 1-1/4 npt male pipe thread, is this cap the right size or am i mixing up sizes

Question by: Sheila F on May 27, 2025, 12:26 PM

It matches 1-1/4 NPT pipe threads. It is made as a protective tear cap for that specific NPT size, so it is intended to go over 1-1/4 NPT threaded ends.

Would these caps keep threads clean if I'm storing some pipe outside for a bit?

Question by: Peggy M on Feb 14, 2026, 6:36 AM

Absolutely, these polyethylene caps are made to protect pipe threads from dirt and damage, so they'll do the job if you're storing pipe outdoors.

these fit standard 1-1/4 NPT pipe threads, or is there some special thread type I need to worry about?

Question by: Larry B on Feb 16, 2026, 10:30 AM

Standard 1-1/4 NPT pipe threads are exactly what these caps are sized for. The NPT designation means National Pipe Taper, which is the most common thread standard used on pipe fittings across industrial and hydraulic applications in North America. If your pipe or fitting uses 1-1/4 NPT threading, this cap will fit.
