0004450092 - ESAB GPB Propane Cutting Tip 15-25mm

Technical Overview of the ESAB GPB Cutting Nozzle

The ESAB GPB Cutting Nozzle (SKU: 0004450092) is a specialized consumable engineered for oxy-fuel cutting processes utilizing alternative fuel gases such as propane and natural gas. This specific model is calibrated for a cutting thickness range of 15mm to 25mm, making it a versatile choice for general fabrication and structural steel work. The nozzle features a two-piece construction, which is standard for propane applications; the outer sleeve protects the inner splines, allowing the fuel gas to burn at the tip face rather than inside the nozzle, preventing overheating and flashbacks common with slower-burning gases.

Manufactured from high-quality copper and brass alloys, the GPB nozzle is designed to withstand the intense thermal cycles inherent in industrial cutting. The internal geometry is precision-machined to ensure a laminar oxygen jet, which is critical for maintaining cut speed and edge quality. The preheat slots are optimized to provide a stable flame ring that brings the base material to ignition temperature efficiently without melting the top edge excessively. This balance of preheat and cutting oxygen flow results in a narrow kerf and reduced slag accumulation.

Compatibility is key with the GPB series; it is designed to fit specific ESAB cutting torches and attachments that utilize the GPB seating style. Operators must ensure their equipment is set to the appropriate pressure settings for propane or natural gas to achieve the rated performance. The 15-25mm capacity covers a significant portion of standard plate thicknesses used in heavy industry, making this nozzle a staple inventory item for maintenance and repair operations.
