Threading directly into 1 NPT pipe threads is what these protective closures handle best. They serve as a tapered plug to keep the inside of your pipes clean before installation.

For a 1 NPT pipe thread, the 1 NPT tapered protective plug is the matching size. It’s made to cap off and protect pipe threads during storage or handling.

these fit standard 1 inch NPT pipe threads, right? just want to make sure before I order a bunch of em

sized for 1 NPT tapered pipe threads. The taper is part of the design, so it seats snugly into the thread profile rather than just sitting loose on the end. If your pipe is 1 inch NPT, you're good to go.
