1403-0039 - Victor Brass Cap Nut 5/16-18 Replacement Hardware

Keep Your Victor Gear Operational with Genuine Parts

When you are out on the job or deep in a fabrication project, the last thing you need is a piece of equipment going down due to a missing or stripped nut. The Victor 1403-0039 Cap Nut is the exact replacement part you need to get your Victor regulators or torches back in action. This isn't just any nut from the hardware store bin; it is a genuine Victor brass cap nut with 5/16-18 threads, designed to fit your specific gear perfectly without forcing threads or risking leaks.

We know that welding gear takes a beating. Regulators get knocked around in the back of trucks, and torches are dragged across shop floors. Over time, small external parts like cap nuts can get lost during maintenance or damaged from impact. This brass cap nut is built to withstand the daily grind. Made from solid brass, it won't rust or seize up like steel nuts can, making future maintenance much easier. The brass construction is also a key safety feature—it won't spark if your wrench slips, which is exactly what you want when working around oxygen and fuel gas cylinders.

This 5/16-18 cap nut is often used to cap off adjustment screws or secure valve assemblies. If you've lost the original, you might be tempted to leave it exposed, but that allows dirt and grinding dust to get into the threads, which can ruin a good regulator over time. Installing this replacement cap nut seals that entry point, keeping the internal mechanics clean and operating smoothly. It’s a small investment that protects the expensive tools you rely on to make a living.

Don't compromise your safety or the performance of your torch setup with mismatched parts. The Victor 1403-0039 ensures that your equipment remains compliant and safe to use. Whether you are fixing up an old SR series regulator or just keeping your spare parts kit stocked for the next emergency, this brass nut is a must-have. It installs in seconds with a standard wrench and gives you the peace of mind that your equipment is assembled correctly with the right materials for the job.
