OVERVIEW

ESAB 53N59 Alumina Gas Lens Nozzle - Size #5

The ESAB 53N59 is a premium-grade alumina ceramic nozzle designed for precision TIG welding applications. Classified as a Size #5 cup, it features a 5/16-inch (approximately 8.0mm) bore diameter, making it an essential component for welders requiring focused gas coverage on medium-to-fine gauge materials. This nozzle is specifically engineered to thread onto gas lens collet bodies found in 9, 20, 24, and 25 series TIG torches.

In industrial maintenance and fabrication environments, the integrity of the shielding gas envelope is critical to preventing atmospheric contamination. The 53N59 works in conjunction with a gas lens to rectify the flow of argon (or helium mixes), transforming turbulent gas streams into a coherent, laminar column. This technical advantage is particularly beneficial when welding reactive metals like stainless steel, titanium, or aluminum, where oxidation must be strictly minimized. The ceramic material is formulated to withstand high thermal cycles, reducing the frequency of replacement due to cracking or heat fatigue.

This product is a direct replacement for standard industry part number 53N59 and integrates seamlessly into existing ESAB or compatible TIG torch setups. It is ideal for MRO operations, aerospace welding, and precision fabrication shops where consistent arc stability and weld cleanliness are paramount. Ensure your inventory is stocked with reliable consumables that support high-quality production standards.

FAQ

It fits WP-9, WP-20, WP-25, and WP-24 series torches equipped with a gas lens collet body.

No, the 53N59 is designed specifically for gas lens collet bodies (like the 45V43, 45V44, 45V45 series). It will not thread onto a standard collet body.

A #5 cup has an inner diameter of 5/16 of an inch, or approximately 8.0 millimeters.

It is made from high-impact alumina ceramic, known for its excellent heat resistance and electrical insulation properties.

Gas lens nozzles provide laminar gas flow, which improves shielding coverage and allows for a longer tungsten stick-out for better visibility.

Yes, 53N59 is a standard industry part number and is generally interchangeable with other major brands of TIG consumables for the same torch series.

This item is typically sold individually (1 per each) unless a bulk pack is specified.

No, 17, 18, and 26 series torches use the larger 54N series cups for gas lenses. This 53N series is for the smaller front-end torches.
