Ridgid 358 Series Carbon Steel NPT Pipe Tap, Right Hand

The Ridgid 358 Series is a family of carbon steel NPT pipe taps engineered for cutting clean, accurate NPT threads in tight, restricted work areas. Available across six model options (35815, 35820, 35825, 35830, 35835, 35840) covering a range of NPT thread sizes, these taps are manufactured in a right hand configuration only and feature the standard NPT taper of 3/4" per foot to ensure proper thread engagement and sealing on every connection. Each tap in the series is clearly marked with the correct drill size for its pilot hole, so plumbers, pipefitters, and electricians can move from drilling to tapping with confidence and minimal guesswork. Backed by Ridgid's reputation for durable, professional-grade threading tools, the 358 Series is built for reliable thread-cutting performance on commercial and residential job sites.

  • Right Hand Configuration: Every model in the 358 Series is produced in right hand configuration only for standard NPT threading applications.

Ridgid RID35-815 – Frequently Asked Questions

1) What NPT thread sizes do the Ridgid 358 Series pipe taps come in?
Six sizes across the 358 Series: 1/8 inch NPT (model 35815), 1/4 inch (35820), 3/8 inch (35825), 1/2 inch (35830), 3/4 inch (35835) and 1 inch (35840). Order by the NPT size you are tapping, and the model number follows it directly.
2) What size pilot hole do I drill before using a Ridgid 358 pipe tap?
You don't have to look it up. Each tap in the 358 Series is marked with the correct drill size for its pilot hole, so the size you need is stamped on the tool you're holding. Drill to that marked size, then run the tap.
3) Are these taps any good for threading in a tight spot where a threading machine won't fit?
That's what they're built for. The 358 Series is a hand tap designed for cutting threads in restricted, hard-to-reach work areas where there is no room for powered threading equipment but the thread still has to be accurate. Turn it with a standard tap wrench.
4) Are Ridgid 358 pipe taps carbon steel or high speed steel?
Carbon steel. That suits hand tapping of steel pipe and fittings at hand speed, which is how these are meant to be run. If you intend to drive a tap under power or into hardened material, a carbon steel hand tap is the wrong choice.
5) Can I use these taps to rethread conduit and fittings, or are they plumbing only?
Both. The 358 Series is used for cutting NPT threads on small-diameter pipe, plumbing and pipefitting installs, and electrical conduit and fitting threading, plus general repair work on commercial and residential sites.
6) Where are Ridgid 358 Series pipe taps made?
The 358 Series pipe taps are made in the United States, which matters if you are buying against a domestic-content requirement on a public or institutional job.
