OVERVIEW

Genuine ESAB Replacement for ST-16 and ST-21 MIG Guns

Maintain the reliability and performance of your industrial welding equipment with the ESAB 996403 ST-16/21 End Fitting. This component is a genuine Original Equipment Manufacturer (OEM) part, specifically engineered to fit the legacy ST-16 and ST-21 series of MIG guns. These torches have long been staples in heavy fabrication environments due to their durability, and keeping them operational requires high-quality replacement parts that meet the original specifications.

The end fitting serves as a critical interface in your welding setup. It is located at the rear of the gun assembly, facilitating the connection between the gun's cable and the wire feeder or power source. Over time, threads can wear, and contact surfaces can degrade due to arcing or mechanical stress. Replacing a worn end fitting with the ESAB 996403 ensures that your torch maintains a secure mechanical grip and, more importantly, a low-resistance electrical connection. This helps prevent heat buildup at the connection point, which is a common cause of erratic arc performance and premature equipment failure.

At Josef Gas, we understand the importance of keeping your production line moving. Finding parts for older but reliable equipment like the ST-16 and ST-21 can sometimes be a challenge, but using genuine ESAB parts guarantees compatibility. This fitting is manufactured to the exact tolerances required for these specific torch models, ensuring a hassle-free installation process. Whether you are repairing a damaged torch or performing routine maintenance to extend the life of your welding assets, this end fitting is an essential component for your repair kit.

Key Benefits:

  • Direct Compatibility: Designed exclusively for ESAB/L-Tec ST-16 and ST-21 platforms.
  • Restored Performance: Eliminates issues caused by loose or corroded connections.
  • Industrial Durability: Built to withstand the rigors of professional welding environments.

FAQ

The ESAB 996403 end fitting is specifically designed for use with ESAB ST-16 and ST-21 series MIG guns.

Yes, this is a genuine ESAB OEM replacement part, ensuring perfect fit and performance for your equipment.

The end fitting connects the MIG gun cable assembly to the wire feeder, facilitating the transfer of welding current, shielding gas, and the welding wire.

This part is listed specifically for the ST-16 and ST-21 models. It is not guaranteed to fit other ESAB torch series such as the PSF or MXH lines without verification.

Over time, end fittings can wear out, threads can strip, or electrical contact surfaces can degrade, leading to overheating and poor weld performance. Replacement restores reliability.

Typically, the end fitting is the metal connector body. O-rings and liners are usually sold separately or as part of a different kit, unless specified otherwise.

The ST-16 and ST-21 are typically air-cooled MIG guns. This fitting is designed for the standard configuration of these torches.
