What is the threading on the 1" flange annular? 16, 14, 8? And the actual id?

Asked by Austinite September 22, 2020

Answer

Hi Austinite, this flange has 11.5 threads per inch and complies with ANSI B1.20.1 threading standards. The ID for this fitting is designed to connect to pipe labeled 1-in which is based on the nominal ID of what conducts the fluid or material being transported. The ID of this fitting is 1.3-in, with a minimal degree of variance. We hope this helps with your project.

I used it under my mailbox to hold it up. I used an iron pipe under it screwed into the flange. The iron pipe is inserted into concrete in the ground. It's all working great.
