CSSC403 - Victor Cutskill SC40-3 Propane Cutting Tip Size 3

High-Performance Smith Style Replacement Tip

The Victor Cutskill CSSC403 is a precision-engineered cutting tip designed to function as a direct replacement for the Smith SC40-3. Engineered specifically for use with alternate fuel gases such as Propane and Natural Gas, this tip is an essential component for industrial cutting operations requiring heavy preheat capabilities and efficient fuel consumption. The SC40 series is renowned for its two-piece construction, which consists of a brass inner member and a copper outer shell. This design allows for the recessing of the inner member, creating a stable flame anchor that remains consistent even when the tip contacts the workpiece.

Advanced Sealing Technology

One of the standout features of this cutting tip is the incorporation of Graf-Tite high-pressure seats. Unlike traditional metal-to-metal seals that can degrade over time or require excessive torque to seal, Graf-Tite material is a resilient, compressible composition that forms a perfect gas-tight seal with minimal wrench pressure. This not only prevents dangerous gas leaks but also significantly extends the service life of the torch head by reducing wear on the seating surfaces. The seats are designed to withstand elevated temperatures, ensuring reliability during prolonged cutting sessions.

Safety and Efficiency

Safety is paramount in oxy-fuel cutting, and the CSSC403 addresses this with its in-tip mix formulation. By mixing the preheat oxygen and fuel gas within the tip itself rather than in the torch handle or tube, the risk of flashback is drastically reduced. This design isolates the combustible mixture to the very end of the assembly. Furthermore, the tip features full swaging of the internal gas passages, a manufacturing process that creates smooth, uniform channels. This reduction in internal friction minimizes gas turbulence, resulting in a laminar flow that produces a cleaner, more precise cut face with less slag accumulation.

Application and Capacity

The Size 3 classification of this tip makes it suitable for cutting mild steel ranging from approximately 1-1/2 inches to 2 inches in thickness. The heavy preheat characteristic of the SC40 design makes it particularly effective for cutting scaly, rusty, or painted steel where a standard tip might struggle to maintain the preheat flame. Whether used in hand cutting torches or machine cutting setups, the Victor Cutskill CSSC403 delivers consistent performance and durability for professional fabricators.
