Suntechmach Pipe Threading Machine, 1/2 to 4 Inch, 900W Motor - ZIT-B4-100

Industrial Threading Machine 4-Inch

The ZIT-B4-100 Pipe Threading Machine is a high-performance, heavy-duty solution tailored for pipe sizes from 1/2″ to 4″, making it ideal for plumbing systems, mechanical workshops, and industrial installations. At the heart of the machine is a robust 900W motor, designed to withstand continuous threading operations without overheating. This is paired with a dual-speed gearbox (11 / 22 RPM), allowing the user to select the ideal speed for different pipe materials and diameters improving die life and thread quality.

Its vibration-resistant metal frame ensures smooth, stable operation even on thick pipes, while the built-in safety systems protect both the user and the motor from overload or sudden faults. The machine is also compatible with BSPT and NPT threading dies, offering maximum flexibility across global standards. Compact yet industrial-grade, the ZIT-B4-100 fits perfectly in confined workshop spaces and delivers uniform, leak-free threads for pressurized systems.
