Ridgid 37480 – Frequently Asked Questions

1) What sizes does the Ridgid 12-R complete die head come in?
Two trade sizes of the Ridgid 12-R high-speed complete die head are offered: 1/2 inch NPT (part number 37480) and 1 inch NPT (part number 37490). Each is a complete die head assembly, so you order one head per pipe size you intend to thread rather than swapping dies within a single head.
2) Will the Ridgid 37490 die head fit my 12-R threading machine?
Yes. The 37490 is the 1 inch NPT high-speed complete die head built for Ridgid 12-R threading equipment, and it mounts and runs without sourcing separate dies or carriers.
3) Does this Ridgid die head cut NPT or BSPT threads?
NPT only. The 12-R complete die head cuts National Pipe Taper threads, which is the thread form standard NPT pipe and conduit fittings in North America require. If your job calls for BSPT, this is the wrong head.
4) Can I use this die head for threading electrical conduit, or is it plumbing only?
Both. The 12-R high-speed die head is used for rigid conduit threading on the electrical side and for plumbing and mechanical piping that needs NPT connections. The thread profile is the same either way, so the head covers both trades at its trade size.
5) What does high-speed mean on a Ridgid 12-R die head?
It means the head is configured for repeatable thread-cutting cycles in production threading work rather than occasional one-off cuts. For a shop fabricating runs of pipe or conduit all day, that is the configuration to specify; for a single repair thread, any 12-R head of the right size will do the job.
6) Is the Ridgid 12-R die head made in the USA?
Yes, the 12-R complete die head is manufactured in the United States, which matters if your contract or procurement spec carries a domestic-origin requirement.
