999605 - ESAB C-Size Brass Hose Nipple for 3/8 Inch ID Hose

Keep Your Heavy Rigs Running with ESAB

When you are running big iron, standard fittings just don't cut it. The ESAB 999605 C-Size Hose Nipple is built for the welder who needs maximum flow and reliability. If you are setting up a heavy-duty cutting torch, a scrap yard rig, or a shop manifold system, you know that C-Size connections (7/8"-14) are the standard for high-volume gas delivery. This nipple allows you to adapt your 3/8-inch heavy-duty hose directly to your equipment, ensuring you get every bit of pressure and flow your regulator puts out.

We know that in the field, a leaky or mismatched fitting isn't just an annoyance—it's a safety hazard and a downtime creator. That is why sticking with trusted brands like ESAB for your terminal connections matters. This nipple is machined from solid brass, meaning it won't deform easily under wrench pressure and stands up to the daily abuse of the shop floor. The barb is sharp and well-defined, biting into the hose liner for a grip that holds fast once crimped or clamped.

Don't let a restricted flow starve your puddle or your preheat. If you are using 3/8" hose, you are doing it because you need the volume. Make sure your fittings aren't the bottleneck. This nipple is the correct match for the larger bore of 3/8" hose, maintaining that volume right into the torch or machine. Whether you are repairing a damaged line or building a custom length hose for a specific job, keep a few of these ESAB C-Size nipples in your kit. They are the professional's choice for heavy-duty gas connections.
