Product Description

The ASHA N.M. Cutting Nozzle Acetylene (Three Seat) (ISI) is designed for professional oxy-acetylene gas cutting applications. Its nozzle-mixing, three-seat design keeps oxygen and fuel gas separated until the nozzle, helping provide stable flame performance and improved resistance to backfire and flashback. The product is identified as Model No. 3012729014, with variants including 1.6 mm (1/16") and 2 mm (5/64").

Technical Specifications

The 1.6 mm variant corresponds to 1/16", while the 2 mm variant corresponds to 5/64".

Key Features

• Three-seat nozzle-mixing design
• Designed specifically for Acetylene gas cutting
• Helps keep oxygen and fuel gas separated until the nozzle mixing zone
• Improved resistance to backfire and flashback
• Designed for stable preheating and cutting flame
• Precision-machined for consistent gas flow
• Suitable for heavy-duty industrial metal cutting
• Available in multiple nozzle sizes
• Designed for use with compatible N.M. three-seat cutting blowpipes

ASHA's three-pipe cutting equipment specifies three-seat nozzles and notes resistance to backfire due to the three-seat arrangement.

Size Options

For reference, comparable N.M. acetylene nozzle specifications show increasing oxygen pressure and cutting capacity with larger nozzle sizes; exact operating pressures should always follow the ASHA nozzle/torch specification.
