Frequently Asked Questions

What is the WIDIA GTD 16239 pipe tap used for?

The WIDIA GTD 16239 is a pipe and conduit thread tap designed for creating NPTF threads in aluminum and other non-ferrous materials. It is commonly used in plumbing, hydraulic, and pneumatic systems where leak-proof connections are required. The H2 hardness and plug chamfer make it suitable for through-hole threading in industrial maintenance and production environments.

What are the specifications of the WIDIA GTD 16239 tap?

The WIDIA GTD 16239 is a 1 1/4"-11.5 NPTF pipe tap with a plug chamfer and 5 flutes. It is made from high-speed steel with an H2 hardness rating. The manufacturer part number is 16239. This tap is optimized for threading aluminum and other soft metals, providing clean, accurate threads for conduit and pipe fittings.

Where to buy WIDIA GTD pipe taps worldwide?

WIDIA GTD pipe taps like the 16239 are available to order through 3G Electric, a global industrial equipment distributor. We source and deliver these taps worldwide, handling full logistics, customs clearance, and delivery to your facility. Contact 3G Electric for pricing and lead time on this WIDIA GTD threading tool.

How to select the right WIDIA GTD tap for aluminum?

For threading aluminum, select a WIDIA GTD tap with a plug chamfer and H2 hardness, like the 16239 model. The 5-flute design helps clear chips efficiently in softer materials. Ensure the tap size matches your NPTF thread requirement (1 1/4"-11.5). Use proper cutting fluid for aluminum to extend tool life and achieve smooth threads.
