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

Asked by Austinite September 22, 2020
1
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.

will this work on a mini 6 ton press?

Asked by Ethan July 20, 2020
1
Answer

Hi ethan, this black floor flange is designed to transport liquids and gasses for plumbing related purposes and has not been designed or tested for such a use. We recommend reaching out to the press manufacturer for their recommendation on your needs as this piece is most likely not a good fit.

What screws can i use with this?

Asked by MelMel April 20, 2020
1
Answer

Hi MelMel, the screws you require depend on the material the floor flange will adhere to. For instance in Home Depot's fasteners section you will find wood screws, bolts, screws for concrete and so on. We recommend checking with local plumbing code and a store associate to help determine your project needs prior to your purchase.

Although it's the correct size it doesn't fit. It stops before becoming flush to the end of the bar. It increased the height by 1/8" on one end, and 1/4" with both caps on. I cannot use the bar due to the increased height.

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.
