Harris LPG (Flat) Cutting Tip – 1NX
General-Purpose Flat Seat LPG Cutting Tip
The Harris 1NX flat seat cutting tip delivers reliable oxy-LPG cutting performance on medium steel sections. As a result, it suits fabrication workshops, structural steel work, maintenance, demolition, and general industrial cutting applications.
Designed for Oxygen and LPG Systems
The 6290-NX series is designed for oxygen combined with LPG, propane, or natural gas fuel systems. Therefore, the 1NX provides stable preheat flames, efficient oxygen cutting, and consistent performance in everyday workshop use.
Flat Seat Design for Secure Fitment
The flat seat interface ensures a tight seal in compatible Harris cutting torches and attachments. Consequently, operators benefit from stable flame control, reduced gas leakage, and consistent cutting performance during operation.
Ideal for 15–25mm Steel Cutting
The 1NX tip typically suits steel in the 15–25mm thickness range depending on setup and operating conditions. In addition, its precision oxygen bore helps produce clean cuts with effective slag removal and reduced post-cut cleanup.
Stable Preheat for Clean Piercing
The preheat flame pattern heats steel quickly and evenly, supporting smooth pierces and controlled cutting starts. As a result, operators achieve improved cut quality and better overall efficiency.
Durable Two-Piece Construction
Harris manufactures the 6290-NX series using a robust two-piece design that improves heat resistance and service life. Consequently, the tip withstands repeated workshop use while maintaining reliable gas flow characteristics.
Suitable for Fabrication and Industrial Work
The 1NX performs well in fabrication shops, construction sites, agricultural repairs, and general maintenance environments. Furthermore, it provides a balanced cutting option between light and heavy-duty tip sizes.
Trusted Harris Oxy-Fuel Performance
Harris oxy-fuel equipment remains widely used across fabrication industries for reliability and consistent cutting results. Likewise, the 1NX delivers dependable LPG cutting performance for everyday professional use.
