375981 - Tweco 375-981 Gas Inlet Fitting for MIG Power Sources

Restore Your Shielding Gas Flow with the Tweco 375981

If you are hearing a hissing sound near your wire feeder or noticing unexplained porosity in your welds, a leaky gas connection might be the culprit. The Tweco 375981 Gas Inlet is the direct replacement part you need to fix gas leaks at the power source connection. As any welder knows, consistent shielding gas coverage is the difference between a stack of dimes and a honeycomb of porosity. Don't let a five-dollar fitting ruin a thousand-dollar project.

This gas inlet is made from solid brass, which means it stands up to the rough conditions of a welding shop. It is designed to thread perfectly into your Tweco setup, replacing stripped, bent, or clogged inlets. Over time, fittings can get banged up during machine moves or stripped during hose changes. When that happens, you lose gas pressure and waste money on shielding gas that never makes it to the puddle. Swapping out a damaged inlet for a fresh 375981 is a quick fix that pays for itself immediately by stopping leaks.

Installation is straightforward. Simply remove the old fitting—being careful not to damage the housing threads—and screw in the new Tweco 375981. Ensure you use the proper wrench size to tighten it down snugly without over-torquing. Once installed, you can trust that your gas flow will be smooth and uninterrupted. This part is a must-have for your spare parts kit, especially if you run older Tweco equipment that sees daily use.

Stop fighting with inconsistent arcs and spatter caused by poor gas coverage. Ensure your machine is running at peak performance with genuine Tweco parts. The 375981 Gas Inlet is a small part that plays a huge role in the quality of your work.
