26422302 - Tweco AK-353-2A Gas Hose Clamp 8.5-10mm for Lincoln MIG Guns

Reliable Gas Connection for Quality Welds

The Tweco AK-353-2A Gas Hose Clamp is a critical component for any professional welder utilizing MIG or TIG processes where shielding gas integrity is paramount. Designed to fit gas hoses with an outer diameter ranging from 8.5mm to 10mm, this clamp ensures a tight, secure seal that prevents atmospheric contamination of the weld pool. In the world of precision welding, even a minor leak in the gas delivery system can lead to porosity, oxidation, and weak weld joints. By utilizing a high-quality clamp like the AK-353-2A, operators can maintain consistent gas flow and pressure, resulting in cleaner, stronger welds.

This specific clamp is identified by the industry-standard part number 2642-2302, making it a direct replacement for compatible Lincoln Electric equipment and Tweco MIG gun assemblies. Its design is optimized for the harsh environment of industrial fabrication shops. Unlike standard worm-gear clamps that can be bulky and prone to loosening over time due to vibration, this style of clamp typically offers a lower profile and a more permanent compression. This reduces the likelihood of the clamp snagging on workpieces or other cables, a common annoyance that can interrupt the welding workflow and damage equipment.

Proper maintenance of the gas delivery system is often overlooked but is essential for cost control. Leaking gas hoses not only compromise weld quality but also waste expensive shielding gas (Argon, CO2, or Tri-Mix). Installing the Tweco AK-353-2A is a cost-effective preventative measure. Whether you are repairing a damaged hose or assembling a new torch setup, this clamp provides the mechanical strength needed to hold the hose firmly onto the barb or fitting, ensuring that the gas goes exactly where it is needed—the weld puddle.

Key Applications:

• Securing gas supply lines to MIG gun power pins.
• Repairing damaged sections of 8.5mm-10mm gas hose.
• Replacing worn or broken clamps on Lincoln and Tweco welding systems.
• General maintenance of industrial gas delivery setups.
