The PRO-SOURCE SQ50D.407023 is a replacement field coil rated at 110 volts for pipe threading machines. The field coil is the stationary electromagnetic winding inside the motor housing that generates the magnetic field needed to drive motor rotation. When a field coil fails, the threading machine loses power or stops running entirely. This part restores full motor function and is installed by pipefitters, plumbers, and mechanical contractors performing field-level motor repairs on threading equipment. The unit ships as a single replacement component and weighs 5.51 pounds.
This field coil is suited for maintenance and repair applications on pipe threading machines in commercial and industrial plumbing environments. It is a direct replacement component intended for technicians who service threading equipment on-site or in a shop setting. The 110-volt rating makes it compatible with standard single-phase power outlets common in plumbing shops and job-site environments.
Designed as an OEM-style replacement field coil for pipe threading machines operating on 110-volt single-phase power. Confirm motor housing dimensions and winding specifications against the existing unit before installation.
Installation should be performed by a licensed plumber or qualified mechanical technician familiar with electric motor service. Disconnect and lock out all power to the threading machine before disassembling the motor housing. Verify that the replacement field coil matches the original winding configuration and voltage rating before reassembly. Follow applicable NEC guidelines for any electrical work performed on the equipment.
