216277 - Miller 216277 Brass Elbow Fitting 1/8 NPT x 1/4 Tubing

Get Your Machine Running with the Miller 216277 Fitting

When you are in the middle of a fabrication project, the last thing you need is a gas leak or a broken fitting inside your welder. The Miller 216277 Fitting is a genuine replacement brass elbow designed to get your Miller welding machine back to peak performance. This small but critical component connects your internal plumbing, handling the transition between threaded ports and flexible tubing. If you have noticed a hissing sound coming from inside your wire feeder or power source, or if you are replacing a cracked fitting during a service check, this is the part you need.

Built from solid brass, this elbow fitting is tough. It stands up to the vibration and heat typical of a welding environment much better than plastic connectors. The 90-degree shape is perfect for tight spaces inside the machine case, allowing hoses to turn corners without pinching off the flow of shielding gas. It features a standard 1/8 NPT thread on one side and connects to 0.250-inch (1/4-inch) tubing on the other. The precision threads mean you won't strip out your solenoid or manifold during installation, provided you cross-reference the part correctly.

Why choose genuine Miller parts? Because fitment matters. Generic hardware store fittings often have slight variances in tolerance that can lead to frustrating leaks or difficult installation. The Miller 216277 is manufactured to the exact standards of your original machine, ensuring a drop-in fit. This fitting is commonly used in the gas delivery systems of various Miller MIG and TIG welders. Keeping your gas lines secure is vital for weld quality; a leak not only wastes expensive argon or CO2 but can also introduce porosity into your welds if air is sucked into the system.

Installation is generally straightforward for those comfortable with basic tool use. Ensure your machine is unplugged and the gas supply is turned off before servicing. Remove the old fitting, clean the threads, and install the new Miller 216277 elbow. It is a simple fix that restores the integrity of your welder's gas system, letting you focus on laying down perfect beads rather than chasing leaks.
