65Z13 - Oxweld 1515-18 Acetylene Cutting Nozzle

Industrial Grade Oxweld 1515 Series Cutting Tip - Size 18

The ESAB Oxweld 1515 Series Size 18 Cutting Tip (SKU: 65Z13) represents the pinnacle of oxy-acetylene cutting technology for heavy industrial applications. Manufactured from a single piece of high-grade copper, this nozzle is designed to withstand the intense thermal cycles associated with prolonged cutting of thick ferrous metals. The one-piece construction is not merely a manufacturing choice but a functional necessity for the 1515 series, allowing for rapid heat dissipation that protects the tip from overheating and deformation during high-amperage equivalent thermal operations.

Engineered specifically for acetylene gas, the 1515-18 utilizes a medium preheat flame configuration, making it versatile for general purpose cutting while excelling in clean, straight cuts on heavy plate. The internal geometry of the tip is swaged to minimize turbulence in the gas stream, ensuring a laminar flow of oxygen and fuel gas. This results in a stable, coherent cutting stream that maintains its integrity over greater distances, essential when severing materials exceeding 12 inches in thickness. The precision-machined seating surfaces ensure a gas-tight fit with compatible Oxweld torches, including the C-31, C-32, and C-66 series, eliminating the risk of leaks that could compromise safety or performance.

In MRO and fabrication environments, the reliability of the consumable is paramount. The ESAB 65Z13 nozzle delivers consistent preheat flames and a powerful cutting oxygen stream, reducing the need for secondary grinding or finishing. Its robust design resists slag adhesion, extending the service life of the tip even in harsh environments such as scrap yards, foundries, and heavy structural steel fabrication plants.
