Question about threading pipe with Ridgid 65-RA

rhodebump

I am threading some pipe with a Ridgid 65-RA and the threads appear to be NPS (they do not taper) like NPT.

I bought/installed a new set of dies (NPT), and threaded pipe. These threads are still not NPT (and the threaded pipe does not fit well into NPT fittings).

I am positive that I installed the dies correctly, and it does make clean threads, but any thoughts on what the problem may be? I would think NPT dies would make NPT threads, but what else may be going on?

Thanks!

Did you set in the new dies in series ? Check the markings.....

I'm not familiar with a 65-RA?

The 65R doesn't use the dies to create taper. It's a receding threader so as you thread it slowly retracts the dies away causing the taper.

The only thought I have is did you set it for normal threads or accidently set it for oversized?

If it was originally a BSPT threader, it can't use NPT dies.



If BSPT dies require a BSPT threader, you can extrapolate that NPT dies require NPT threader.

That is so helpful! Thank you! You can't teach an old threader new threads

I am going to try one more time with my NPT dies and use exactly the standard depth setting. I did go beyond the standard setting thinking that it would create more threads on the pipe, not deeper ones.

Not sure if a visual would help anyone, but here is a listing on ebay showing a 65-RA threader.

The difference between the letters at the end is only how it clamps/holds the pipe. Rest is the same
