Ridgid 50705 Pipe Die 1/4-18 Npt Right Hand Thread

Product Description

The RIDGID 50705 is a right-hand pipe die designed to cut 1/4-18 NPT threads on pipe for use in plumbing, gas, and mechanical piping systems. Manufactured from high speed steel, the die delivers consistent thread geometry and extended service life under repeated use. This die is engineered to produce tapered NPT threads that conform to standard pipe fitting specifications, making it a standard tool in any licensed plumber or pipefitter's inventory. Installation is performed by threading professionals and pipefitters working on ferrous and non-ferrous pipe in residential and commercial applications.

The 50705 is sized for 1/4-18 NPT threading, a common specification found in low-pressure gas lines, water supply piping, instrument connections, and pneumatic fittings. It is suited for trade professionals performing field threading operations where a portable or bench-mounted threading machine is in use. The right-hand thread direction matches the standard installation direction for NPT pipe fittings used throughout North American plumbing and mechanical systems.

Installation Notes

This die is installed and operated by licensed plumbers, pipefitters, or mechanical contractors using a compatible die head and threading machine. Ensure the threading machine is powered off and the pipe is securely clamped before installing or removing the die. Apply appropriate thread cutting oil during operation to extend die life and produce clean thread form. Follow applicable plumbing and mechanical codes, including IPC and IFGC requirements, when threading pipe for pressurized systems.
