  • Did I Buy The Wrong Dies for my Model 300 Pipe Threader

    Hey yall.
    I just bought new dies for my 611 head and my Universal head. I am cutting and threading black pipe for gas. I am going to try to include pics so that my problem may be easier to understand.

    I bought Ridgid Cat. No. 47765 for 1/2" - 3/4" NPT & Ridgid Cat. No. 47770 for 1" - 2" NPT.

    The problem I am having is when I close my dies, I set it for 1 1/2" (matching the lines) to thread 1 1/2" pipe. When finished, a fitting in no way will screw on the newly threaded pipe. So, I keep repeating this cutting UNDER, further UNDER, until I am halfway to 1 1/4". Then, When the fitting is finally able to screw on, it's got alot of play until the pipe is anywhere to 1/4" inside the fitting before it begins to catch threads.

    No, I am not threading beyond the die. But I'll say that if I try to thread an 1 1/2" pipe at the final setting that allowed the fitting to screw on, the motor bogs down, the oil is smokin- something isn't right.

    Anyone have any ideas?

    no expert here, but since no one has chimed in, the numbers look corrects there are the NPT dies, Pipe & Bolt Dies for Machine Die Heads - RIDGID Professional Tools

    but I do not see a 611 head but I do see a 811a head,
    Optional Die Heads - RIDGID Professional Tools

    300 Compact Threading Machine - RIDGID Professional Tools
    300 manual looks like the setting of the die head is on page, 12 or 13 of the manual not the PDF,

    Looks like to me that your cutting under sized threads, and you need to make some type of adjustment on the die head, is my guess,

    as I look at the picture more it looks like it is cutting a straight thread instead of a tapered thread, (the only suggestion I would have is to take one of the dies out of head and compare to the old dies, and see if there could have been some type of packaging error,

        I am assuming you are using an 811A Die Head. If you are, the dies you purchased are the correct dies.

        I have a few questin that will help resolve the problem:

        What does the OD of the pipe your are threading measure (1-1/2" = 1.900 OD)?
        How old is the die head?
        What is the model number and age of the Threading Machine?

        Please forward a photo of the die head.
