18K05 - ESAB Oxygen Adapter - B-Size Male to 3/8 Inch Tube

Reliable Connections for Your Oxy-Fuel Gear

When you are setting up your rig or fixing a gas line, having the right fitting can make the difference between a job well done and a safety headache. The ESAB 18K05 Adapter is built for welders who need to convert a standard B-Size Oxygen connection to a 3/8" tube line. Made from heavy-duty brass, this little lifesaver stands up to the wear and tear of the shop, resisting rust and stripping so you can crank it down with confidence.

We know that oxygen leaks are no joke. That's why sticking with trusted brands like ESAB for your "small parts" is a smart move. This adapter features the industry-standard Right-Hand thread for oxygen (so you don't accidentally hook it up to fuel) and transitions smoothly to a 3/8" tube interface. It's perfect for those custom setups where off-the-shelf hoses just don't fit, or when you are plumbing in a permanent manifold system for your cutting table.

Don't let a missing ten-dollar part shut down your fabrication project. Keep a few of these adapters in your kit. Whether you are adapting a regulator, extending a line, or building out a custom gas distribution system, the ESAB 18K05 gives you the tight, secure seal you need to keep the flame burning steady and safe.
