281442 - Miller 281442 Mini TPA2 Connector Pin 18-20 AWG (Pack of 4)

Maintain Circuit Integrity with Miller OEM Parts

The Miller 281442 Connector Pin is a critical component for maintaining the electrical reliability of your Miller welding equipment. Designed as a Rectangular Mini TPA2 Pin, this terminal is engineered to fit securely into specific connector housings found within the internal wiring harnesses of various Miller machines. When electrical faults occur due to corroded or damaged pins, using genuine OEM replacements is essential to ensure the machine operates within factory specifications.

Manufactured from high-grade brass and finished with a durable tin plating, these pins offer excellent electrical conductivity while resisting oxidation and corrosion. This is particularly important in industrial environments where moisture and temperature fluctuations can degrade inferior connections over time. The tin plating also facilitates a smooth mating action, reducing wear on the corresponding socket terminals during maintenance or assembly.

These pins are sized specifically for 18-20 gauge (AWG) wire, a common size for control signals and low-power circuits in welding power sources. The 0.1120-inch diameter specification ensures compatibility with the appropriate wire insulation and connector seals. Proper crimping of these pins onto the wire ensures a gas-tight seal that prevents resistance buildup and potential signal loss.

Supplied in a convenient package of 4, this kit allows technicians to repair multiple connections or keep spares on hand for emergency repairs. Whether you are troubleshooting a control board issue or repairing a damaged wire harness, the Miller 281442 provides the quality and fitment required for professional results.
