0309-0018 - Victor Brass Tip Nut for 300 Series Torches and Series 1 Tips

Precision Brass Tip Nut for Victor Series 1 Cutting Attachments

The Victor 0309-0018 Tip Nut is a critical component designed to secure Series 1 cutting tips to compatible Victor torches. Manufactured from high-quality brass, this tip nut ensures a tight, leak-proof seal between the cutting tip and the torch head, which is essential for maintaining safe and efficient oxy-fuel cutting operations. The nut features a precise 15/16" - 18 thread, engineered to withstand the thermal expansion and contraction cycles typical in heavy-duty industrial environments.

This OEM replacement part is specifically designed for use with Victor MT 400, ST 1800C, and ST 1900C series torches, as well as other handles compatible with Victor 300 Series equipment. The brass construction not only provides excellent durability against heat and spatter but also prevents galling on the torch head threads, prolonging the lifespan of your expensive cutting equipment. A compromised tip nut can lead to gas leaks, flashbacks, or poor cut quality due to tip misalignment; therefore, regular inspection and replacement of this component are recommended for professional fabricators.

Weighing approximately 0.8 lbs, this nut is machined to exact tolerances. It acts as the primary retention mechanism for the cutting tip, ensuring that the preheat and cutting oxygen gases flow through the intended channels without cross-contamination or leakage at the seating surface. Whether you are operating in a fabrication shop, a scrap yard, or on a construction site, relying on genuine Victor parts guarantees that your equipment performs to the manufacturer's safety and efficiency standards.

Installation is straightforward but requires care to avoid cross-threading. The hex design allows for easy tightening with a standard wrench, ensuring the tip is seated firmly against the torch head. By maintaining the integrity of your torch's front end with a fresh tip nut, you ensure consistent flame characteristics and operator safety.
