Pro-source 54N16 Tig Torch Nozzle 0.375 Inch Orifice

Product Description

The PRO-SOURCE 54N16 is a replacement TIG torch nozzle designed to direct and shape the shielding gas flow around the tungsten electrode during gas tungsten arc welding (GTAW) operations. With an orifice size of 0.375 inches, this nozzle controls the gas coverage envelope at the weld puddle, helping maintain arc stability and protect the weld zone from atmospheric contamination. The nozzle measures 1.68 inches in length and 0.97 inches in width, and weighs approximately 0.056 pounds. It is a consumable component replaced routinely by welding technicians and fabricators as part of standard torch maintenance.

This nozzle is suited for use on compatible TIG torches in light-duty to medium-duty welding applications, including fabrication shops, maintenance and repair operations, and field welding work. The 0.375 inch orifice size is a common specification used in a range of TIG torch configurations. Technicians working on ferrous and non-ferrous metals such as stainless steel, aluminum, and mild steel will find this nozzle appropriate for general-purpose shielding gas coverage requirements.

Key Features

• 0.375 inch orifice size for controlled shielding gas coverage at the weld zone
• Compact form factor: 1.68 inches long, 0.97 inches wide
• Lightweight at 0.056 pounds, minimizing added torch weight
• Sold individually as a replacement consumable for routine torch maintenance
• Designed as a direct-replacement nozzle for compatible TIG torch bodies

Compatibility

Designed as an OEM-style replacement nozzle for compatible TIG torch assemblies requiring a 0.375 inch orifice nozzle. Verify torch body and nozzle thread or slip-fit specifications before installation.

Installation Notes

TIG torch nozzles are installed and replaced by qualified welders or welding maintenance technicians. Always power down the welding machine and allow the torch to cool completely before removing or installing nozzles. Inspect the collet body and gas lens for wear or contamination during nozzle replacement. Follow manufacturer torch assembly guidelines and applicable AWS safety standards during torch servicing.
