598891 - ESAB #10 Alumina Gas Lens Cup (Pack of 2) - 598891

Precision Shielding with ESAB Alumina Gas Lens Nozzles

The ESAB 598891 Alumina Gas Lens Nozzle is a premium consumable designed for professional TIG welders who demand superior gas coverage and weld consistency. This Size #10 nozzle features a 5/8-inch (approx. 16mm) bore, making it an excellent choice for applications requiring a broad shield of inert gas, such as welding stainless steel, titanium, or aluminum alloys where oxidation must be strictly minimized. Manufactured from high-grade alumina ceramic, these nozzles offer exceptional thermal shock resistance, ensuring they can withstand the rapid heating and cooling cycles inherent in industrial welding environments without cracking or failing prematurely.

Designed specifically for use with gas lens collet bodies, this nozzle helps generate a laminar gas flow. Unlike standard collet bodies that can create turbulent gas streams, a gas lens organizes the argon flow into a coherent column. This allows the welder to extend the tungsten electrode further out from the nozzle—improving visibility in tight corners and deep joints—while maintaining adequate shielding. The ESAB 598891 is fully compatible with industry-standard 17, 18, and 26 series TIG torches (including HW-17, HW-18, HW-26, and equivalent models from other brands), making it a versatile addition to any fabricator's toolkit.

At Josef Gas, we understand that the quality of your consumables directly impacts the quality of your bead. Using genuine or high-quality equivalent ceramic cups like the ESAB 598891 ensures that your gas lens setup performs at its peak. This product comes in a convenient pack of 2, ensuring you always have a spare on hand during critical production runs. Whether you are fabricating aerospace components, food-grade stainless vessels, or precision automotive parts, these nozzles provide the reliability and performance required for X-ray quality welds.

Key Technical Benefits:

• Enhanced Visibility: Allows for longer electrode stick-out (up to 1 inch in some conditions) due to the coherent gas stream.


• Durability: High-impact alumina ceramic resists chipping and thermal stress.


• Compatibility: Fits standard "large" gas lens setups on air-cooled and water-cooled torches.
