The RIDGID RT3422 NPT Set (75992) Tapping Tool with NPT Male Adapters is designed to perform pressurized taps using a saddle-mounted valve or welded nipple on steel, plastic, ductile iron and cast iron pipe. It is ideal for branching pressurized water, steam and natural gas mains.
The RT3422 is capable of tapping water lines under pressure up to 500 psi, or steam, air, and natural gas mains up to 150 psi. Weighing only 18 lbs, the RT3422 can produce 3/4" to 2" taps quickly and easily. The cutter is rotated by an 11/16" hand ratchet or can be operated by an air ratchet or right angle drill if desired. A self cleaning Acme threaded barrel permits easy feeding of the cutter into the pipe and resists the force of the pressurized pipe when the cut is made.
