30451790 - Tweco Threaded Conductor Tube Nipple with O-Ring

Genuine Tweco 3045-1790 Threaded Nipple with O-Ring

The Tweco 3045-1790 is a critical replacement component designed for professional MIG welding guns, specifically within the Tweco Spray Master series and compatible assemblies. This threaded nipple serves as the connecting interface between the conductor tube (gooseneck) and the cable adapter or gun body block. Manufactured from high-grade brass, it ensures optimal electrical conductivity, which is essential for maintaining a stable arc during welding operations.

One of the primary functions of this component is to maintain the integrity of the shielding gas flow. The included O-ring is pre-seated to provide a hermetic seal, preventing gas leakage that could lead to porosity in the weld or wasted shielding gas. Over time, heat cycles and mechanical stress can wear down threads or dry out O-rings; replacing the nipple assembly is a standard maintenance procedure to extend the life of your MIG gun.

Industrial environments demand reliability, and using genuine Tweco parts guarantees that tolerances match the original equipment specifications. This part is easy to install and is a direct fit for the designated Tweco gun models, minimizing downtime during repairs. Whether you are refurbishing a fleet of welders or performing a quick field repair, the 3045-1790 offers the durability and precision required for heavy-duty fabrication.
