Product Review

Designed for use with the RIDGID line of power drive pipe threading machines, the RIDGID 36890 Alloy Die Head comes with 1/2-inch (12 mm) high-speed dies and a capacity for cutting clean, precise threads in mere seconds. This is the tool you want for quick, efficient pipe threading. The convenient, factory set 12R RIDGID die head is built for longevity and creates an American Standard National Pipe Thread (NPT) seal that is ideal when cutting threads for mechanical, low-pressure air or fluid applications.

The super-efficient OO-R model produces exacting right-hand directional threads on metal pipes that measure up to 1/2-inch (12 mm) NPS, creating clean 14 TPI. RIDGID covers its products with a lifetime warranty against defects in material or workmanship for the life of the tool.

Since 1923, RIDGID has remained the symbol of certainty to dedicated professionals of the expert trades. Every tool that bears the RIDGID brand is engineered to the same high standards of quality, strength and endurance, as was that first heavy-duty pipe wrench more than 80 years ago.
