Rated 5 out of 5 by from Great product. I have used ridgid tools for over 30 years in the refrigeration trade. Great tools I would not use any other.

Rated 5 out of 5 by from Easy to use Very pleased, question: can or has anyone ever put the dies in the opposite direction? I have a situation where the pipe I am threading has an obstacle not allowing threader to complete its cut completely.

Is there a certain set of dies needed for working with aluminum pipe or conduit?

Asked by: MarkusSarkus
Thank you for being a Ridge Tool customer. The alloy dies will work for aluminum. For example, NPT thread 1/2" would be catalog number 37825.

Will the ratchet threader dies work on a ridgid 600 threader?

Asked by: Squiggs99
Yes, the 11-R ratchet threader heads are the dieheads that the 600pd uses. I have attached a list of the 11-R dieheads that has the catalog numbers you would be able to order them by.

what does the # g18 mean on my 1' threader die head, what model handle would i use for it

Asked by: steve68
This number isn’t used for identification purposes. It is merely a number that is cast into the Die Head at the foundry. It may identify the mold area that it was cast in. Please contact us directly at 888-743-4333 so we can try to help you identify what you've got and get you to technical services.
