Product Q&A
13 QuestionsQ: Is this nipple continuously threaded? Approximately how much space is in the middle of the nipple (the part that is not threaded)? Thanks!
Asked by Rae 13 years ago

Overall length is 12" there is about 10" of none thread between the 2 ends
No - it is taper threaded like all pipe thread. The space in the middle varies on each piece.
The picture is misleading - it looks like it is for a 1/2" close nipple, not for a 12". The threaded portion of a 1/2" nipple will be about 5/8" on each end. The rest will be unthreaded.
Hi, The nipple in question is not continually threaded and has an unthreaded area of roughly 1/2". A fully threaded nipple is called a "close" nipple. Keep in mind the threads are opposite directions on both ends (each end is a right handed thread). I hope this helps answer your question. John Sent from my iPhone
This is a 12" long nipple. It is only threaded about 3/4" on each end. The remaining portion is unthreaded.
It's continuous
It is not. The picture is generic. You've selected a 1/2" x 12" nipple, which is 12 inches long. The threading is pipe thread (NPT) which has a taper to it so it is not possible for the threading to be continuous. Only the end 1 inch or so is threaded.
Mine was threaded continuously the whole way through.
You should have about 3/4"thread on each end with approx. 10 1/2"of smooth or unthreaded pipe in between . That would be for a 1/2"x 12" nipp. Sent from my I phone Stan

Q: 1.5inches is that OD or ID how are pipe named?
Asked by Hulk 14 years ago
Add your answer
When dealing with galvanized or iron pipe all measurements are ID. The 1-1/2" x 5-1/2" Black Nipple would have 1-1/2 ID and a 2" OD
The 1.5 inches is the inside diameter of the pipe.
Pipe sides are approximately ID. The standard says that tubing sizes are OD and pipe sizes are ID. But the exact inside diameter of all pipe varies with the strength of the pipe, that is, the thickness of the wall (called the "schedule" of the pipe). So schedule 40 pipe, for example, the lighter wall pipe, will have a slightly larger ID than Schedule 80, the thicker wall of which occludes some of the ID. The exception to this rule is hard drawn copper water tube, sometimes incorrectly called copper pipe. Copper water tube sizes are again approximately ID. Soft copper tubing, which comes in rolls is available in either pipe diameters (ID) or tubing diameters (OD). Confused? No wonder.
IPS: internal pipe sizeNPT:nominal pipe thread pipe nipples are sized by inside diameter
It is the inside diameter or ID
