GPN-3 - Flame Tech GPN-3 Propane Cutting Tip Size 3 for Victor 300 Series

Industrial Grade GPN-3 Cutting Tip for Propane & Natural Gas

The Flame Tech GPN-3 is a high-performance cutting tip engineered specifically for use with alternative fuel gases such as propane and natural gas. Designed as a direct replacement for Victor® style equipment, this Size 3 tip is fully compatible with Victor 300 Series cutting attachments and handles. It is precision-manufactured to meet the rigorous demands of heavy industrial applications, including structural steel fabrication, scrap processing, and shipyard maintenance. The GPN-3 is rated for cutting mild steel with a thickness of approximately 2 inches (50mm), making it a versatile choice for mid-to-heavy range cutting tasks.

Unlike standard acetylene tips, the GPN-3 utilizes a two-piece construction method which is essential for the efficient combustion of slower-burning fuel gases like propane. The assembly consists of a brass inner spline and a heavy-duty copper outer shell. The brass spline is machined with precise grooves that direct the pre-heat gas mixture, ensuring a stable and uniform flame ring. The outer copper shell acts as a heat shield, protecting the inner components from the intense reflected heat of the cutting process while also resisting spatter adhesion. This separation of components allows for easier maintenance; the outer shell can be removed to clean the splines of soot or debris, significantly extending the service life of the consumable.

Flame Tech's commitment to quality ensures that the GPN-3 delivers consistent gas flow and optimal oxygen stream velocity. The seating surfaces are machined to tight tolerances to prevent gas leaks and flashbacks, ensuring operator safety. By optimizing the pre-heat flame characteristics for propane, this tip provides a clean, slag-free cut that reduces the need for secondary grinding or machining. Whether utilized in a stationary cutting machine or a manual hand torch, the GPN-3 offers reliability and efficiency for professionals who demand precision in their oxy-fuel cutting operations.

Switching to propane or natural gas with the GPN-3 can also offer significant cost savings over acetylene without compromising on cut quality for thicker sections. The tip's design maximizes the thermal efficiency of the fuel gas, providing deep heat penetration and fast cutting speeds. This product represents a robust solution for MRO (Maintenance, Repair, and Operations) professionals seeking durable, high-quality consumables for their Victor-style apparatus.
