Value Collection 315-2120 Adjustable Pipe Die 1/8-27 Npt

Product Description

The VALUE COLLECTION 315-2120 is a round adjustable pipe die designed to cut 1/8-27 NPT external threads on pipe and fittings. Manufactured from high-speed steel, it delivers consistent thread geometry and extended service life under repeated use. The adjustable design allows the cutting diameter to be fine-tuned, accommodating minor stock variations and enabling thread quality adjustments without replacing the die. With a 1-1/2 inch outside diameter, the die seats in standard die stocks of the matching size. Plumbers, pipefitters, and general tradespeople use this die for threading soft steel, iron, and similar pipe materials in field or shop conditions.

This pipe die is suited for threading 1/8-inch nominal pipe where NPT-standard tapered threads are required. Typical applications include fabricating threaded connections on gas, water, and compressed-air piping systems at residential and light commercial job sites. The right-hand thread direction is standard for NPT fittings and matches the vast majority of pipe threading tasks. It is used with a compatible 1-1/2 inch OD round die stock and a cutting oil to maintain edge life and thread finish.

Installation Notes

Installation of this die should be performed by a qualified plumber or pipefitter familiar with pipe threading equipment. Secure the die stock firmly before engaging the pipe, and apply cutting oil throughout the threading process to protect the cutting edges and improve thread finish. Always deburr and clean the pipe end before threading. Inspect the finished thread with a compatible NPT fitting or thread gauge before making a pressure connection.
