Ridgid Pipe Threader Adapters for Large-Size Pipe

Mount these adapters to your Ridgid 300 or 535A electric pipe threader to cut threads into large-size pipe and conduit. The adjustable die head threads pipe sizes 2 _1/2, 3, 3 _1/2, and 4 with a single set of dies that you don’t have to change out as you work on various pipes. You can also switch from tapered (NPT) to straight (NPSM) threading with the flip of a handle. Twist these adapters by hand to tighten them securely around pipes before threading – no specialized tools needed. Once threading is complete, they automatically stop rotating to keep pipes from jamming in the dies, preventing damaged threads and delayed projects.

Adapters come with a Ridgid No. 38120 die set to cut threads in steel pipes. Mounting kits (sold separately) are required to connect the adapters to Ridgid 535A pipe threaders. To use these adapters with Ridgid 300 pipe threaders, you will need a connector loop and drive bar (sold separately).

Pipe Threader Adapter Accessories and Replacement Parts

Ridgid No. 70640 Die Set—Use these dies if you need to cut threads in stainless steel pipe. The angled teeth stay sharp and cut cleanly for repeated use.

Ridgid No. D-1440 Ratchet and Handle—No electric pipe threader, no problem. Attach the ratchet and handle to the adapter to cut threads by hand. Although manually threading one pipe can take up to 30 minutes, it’s ideal when you need to avoid generating electrical sparks in environments where flammable materials are present.

Ridgid No. 96725 Case—Keep your adapter working like new for years. Made from powder-coated steel, these sturdy cases keep out moisture, dust, and grime.

Ridgid No. 840A Universal Drive Shaft—Thread pipes that can’t be budged, such as those mounted through walls or attached to pipelines. The shaft rotates the adapter, instead of the pipe, to cut threads.
