OVERVIEW

Reach Tight Spaces with the Weldcraft 57N75L Long Nozzle

Every TIG welder eventually encounters a joint that seems impossible to reach. Whether you are welding a roll cage, working inside a collector, or repairing a casting with deep recesses, a standard nozzle often gets in the way before your tungsten can reach the root. The Weldcraft 57N75L Alumina Gas Lens Nozzle is the solution to these frustration-inducing scenarios. With a length of nearly 3 inches (69.8mm), this "Long" style nozzle acts as an extension for your torch, allowing you to slip the cup into narrow gaps while keeping your hand at a comfortable distance.

This nozzle is a Size #6, meaning it has a 3/8-inch opening. This is a versatile size that balances gas coverage with profile width, making it narrow enough for tight spots but wide enough to provide adequate shielding for most steel and stainless steel applications. Because it is designed for use with a gas lens, you get the added benefit of a coherent, laminar gas stream. This is crucial when using a long nozzle because you will often need to extend your tungsten electrode further out than usual to see what you are doing. The gas lens keeps that long stick-out protected, preventing porosity in your welds.

Durability is standard with Weldcraft products. Made from pink alumina ceramic, this nozzle stands up to the heat of daily welding. It resists impact better than lower-quality ceramics, meaning it won't chip the first time you set your torch down a little too hard. It fits all standard 17, 18, and 26 series torches (including WP-17, WP-18, and WP-26) equipped with a gas lens setup. If you are currently using a standard collet body, remember you will need to swap to a gas lens collet body to use this cup.

Adding the 57N75L to your kit gives you a strategic advantage. You might not use it on every weld, but when you have a job that requires deep access, this nozzle turns a nightmare weld into a manageable one. It is an essential accessory for fabricators who demand precision and versatility from their equipment.

FAQ

The 57N75L fits 17, 18, and 26 series TIG torches, including WP-17, WP-18, and WP-26 models.

Yes, this is a gas lens nozzle. You must use it with a gas lens collet body (e.g., 45V series), not a standard collet body.

The nozzle is approximately 2-3/4 inches (69.8mm) long.

A #6 nozzle has an orifice diameter of 3/8 of an inch, or approximately 9.6mm.

A long nozzle allows you to reach into tight spaces, corners, or deep recesses that a standard short nozzle cannot access.

Yes, it is made of high-impact alumina ceramic, which offers excellent heat resistance.

Yes, provided you are using the correct AC settings and tungsten for aluminum, this nozzle is suitable for the gas coverage required.

No, this product is the ceramic nozzle cup only. Insulators and collet bodies are sold separately.
