0309-0003 - Victor 0309-0003 Brass Tip Nut for Series 3 Cutting Tips (7/8-20 Thread)

Technical Overview of the Victor 0309-0003 Tip Nut

The Victor 0309-0003 Tip Nut is a critical replacement component designed specifically for securing Series 3 cutting tips to compatible Victor cutting attachments. Manufactured to precise OEM specifications, this nut features a 7/8" - 20 thread pitch, ensuring a tight and accurate fit that is essential for maintaining the integrity of the gas seal between the cutting tip and the torch head. A compromised seal can lead to backfires, poor flame quality, or hazardous gas leaks, making the condition of the tip nut a vital safety consideration in any oxy-fuel setup.

Constructed from high-grade brass, this tip nut offers excellent thermal conductivity and resistance to the high temperatures generated during cutting operations. Brass is the material of choice for this application due to its durability and resistance to seizing, allowing for easier removal and replacement of tips even after repeated heating cycles. The nut is engineered to withstand the mechanical stresses of daily industrial use while protecting the seating surfaces of the torch head.

This specific part is compatible with a range of Victor cutting attachments, primarily those found in the 100 Series medium-duty outfits. Verified compatibility includes the CA 1260, CA 1450, CA 2050, and C1400C series attachments. It is designed exclusively for Series 3 cutting tips (such as the 3-101 acetylene tips or 3-GPN propane tips). Industrial maintenance professionals and procurement specialists should verify the torch model series before ordering to ensure this 7/8"-20 nut is the correct specification for their equipment.

Regular inspection of torch components is recommended. If the threads on your current tip nut show signs of wear, cross-threading, or physical deformation, immediate replacement with this genuine Victor 0309-0003 part is necessary to restore the equipment to safe operational standards.
