58V58 - ESAB Western Style Bulkhead Adapter 5/8-18 RH Female x 1/4 NPT Male

Upgrade Your Welding Rig with Secure Gas Connections

When you are building a custom welding cart or fixing up an older machine, routing your gas lines cleanly is what separates a pro setup from a messy one. The ESAB 58V58 Bulkhead Adapter is the perfect solution for passing your shielding gas through the wall of a cabinet, the back of a welder, or a custom mounting plate. No more running hoses through jagged holes with grommets that fall out; this brass fitting gives you a solid, leak-proof connection point that looks factory-made.

This adapter is built tough from solid brass, so you don't have to worry about stripping threads or cracking the body when you tighten it down. On one side, you have a 5/8"-18 Female thread—that's the standard "B-Size" fitting that connects directly to your Argon or Argon/CO2 mix regulator hoses. On the other side, you get a 1/4" NPT Male thread, which is the industry standard for screwing into manifolds, solenoids, or other hard piping. Because it is a bulkhead fitting, it is designed to be mounted through a surface, creating a stationary point where you can connect your gas supply on the outside and your internal plumbing on the inside.

Whether you are a TIG welder running pure Argon or a MIG welder using a mix, this fitting handles inert gases safely. It is compatible with Nitrogen and Helium systems as well. If you have ever dealt with a leaky gas connection inside a machine, you know how frustrating it can be to diagnose porosity in your welds. Using high-quality fittings like the ESAB 58V58 ensures that your shielding gas gets to the puddle without sucking in atmosphere along the way.

Don't settle for makeshift plumbing on your expensive equipment. Use the ESAB 58V58 to create a clean, professional, and safe gas delivery system. It is a small part that makes a big difference in the organization and reliability of your welding station. Keep one in your toolbox for those unexpected repairs or your next big shop project.
