Cutting Nozzle (Flat Seats Nozzle) ｜ Flat Contact Structure, Durable and Ideal for LPG Cutting in Thin–Medium Plate Ranges

• The Flat Seats Nozzle features a flat contact structure that enhances tight gas sealing and stable gas delivery

• Ideal for Oxy-Fuel cutting applications using LPG as the fuel gas

• Supports thin to medium plate cutting in the range of 3–30 mm

• Durable flat contact structure, suitable for field work and continuous operation

ーーーーーーーーーーーーーーーーーーーーーーーーーーーーーーー

In gas cutting operations, flame stability does not depend solely on the torch itself, but also on the sealing structure and gas distribution of the nozzle. The Flat Seats Nozzle is designed with a flat contact surface between the nozzle and the torch, allowing tight fitting, reduced gas leakage, and stable flame performance. It is well suited for general cutting work that emphasizes durability and ease of maintenance.

At job sites where nozzles are frequently removed and installed, contact surfaces can become scratched, worn, or lose sealing performance. The Flat Seats Nozzle reduces these issues through a simple, robust structure that is easy to set up and use.

A key feature of the Flat Seats Nozzle is its flat contact surface, which distributes clamping force evenly, minimizes gas leakage at the connection point, and helps maintain a consistent flame shape. It is suitable for cutting applications that do not require high cutting power, especially LPG cutting where stable combustion is essential.

Gas: LPG

Plate thickness: 3–30 mm

Sizes: No. 0 / 1 / 2

Compatible with: YAWATA

The Flat Seats Nozzle is widely used in fabrication lines for thin to medium plate cutting, field work requiring durability, and factories that primarily use LPG as their fuel gas.

Selecting the appropriate Flat Seats Nozzle according to the torch and fuel gas type improves Oxy-Fuel cutting stability, reduces gas leakage, minimizes flame interruption, and shortens downtime caused by repeated adjustments.

The Flat Seats Nozzle is a cutting nozzle that emphasizes simplicity, durability, and practical usability. It is ideal for LPG cutting in thin to medium plate ranges, providing stable flames, easy maintenance, and long-term cost effectiveness for general cutting applications.

Q: How does the Flat Seats Nozzle differ from 2 Seats or 3 Seats types?

A: The Flat Seats type focuses on a simple structure, tight sealing, and easy maintenance, making it suitable for general cutting work, while 2 Seats and 3 Seats types are designed for higher stability in heavy-duty or thick plate cutting.

Q: Which fuel gas is the Flat Seats Nozzle suitable for?

A: The NCC-H model is specifically designed for LPG to ensure stable and safe combustion.

Cutting Nozzle: A component of a cutting torch that controls flame shape and the injection of cutting oxygen

Flat Seats Nozzle: A nozzle with a flat contact surface designed to enhance gas sealing and durability

Gas Sealing: A sealing structure designed to prevent gas leakage

Oxy-Fuel Cutting: A metal cutting process that uses oxygen in combination with fuel gas
