056851 - Miller Brass Hose Barb Fitting 3/16 Inch

Fix Your Welder with the Right Parts

Keep your Miller welder running smoothly with the Miller 056851 Brass Barbed Nipple Fitting. If you've noticed a leak in your gas line or are replacing old, cracked hoses inside your machine, you know that the small connections matter just as much as the big power source. This fitting is a genuine Miller replacement part, meaning it is the exact piece your machine was built with. No more guessing at the hardware store or trying to force a generic fitting that "looks close enough" into place.

This fitting is made from solid brass, which is tough enough to handle the workshop environment. Brass doesn't rust like steel and won't crack like plastic, making it perfect for the gas and water lines inside your welder. The barbed end is designed to slide into 3/16-inch tubing and hold on tight. Once you clamp it down, you get a secure, leak-free connection that ensures your shielding gas actually makes it to the torch—saving you money on wasted gas and preventing porosity in your welds caused by air leaks.

Whether you are fixing up an old reliable MIG runner or servicing a TIG cooler, having the right small parts on hand makes the job go faster. This nipple is commonly used in various Miller wire feeders and power sources. It's a small, affordable part that plays a big role in the consistency of your welding arc. Don't let a ten-cent leak ruin a thousand-dollar job; swap out your worn fittings with genuine Miller replacements and weld with confidence.

Application Notes

This fitting is designed for 3/16" ID tubing. It is commonly found in internal gas hose assemblies and coolant paths. Always check your machine's parts manual to confirm the part number before ordering. Installation is straightforward: simply push the tubing over the barbs and secure it with a hose clamp or ferrule for a permanent fix.
