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

Miller 216277 Brass Elbow Fitting Overview

The Miller 216277 Fitting is a specialized brass elbow component designed for use in Miller welding equipment. As a genuine OEM (Original Equipment Manufacturer) part, it is engineered to meet the exact specifications required for maintaining the integrity of your machine's internal systems. This fitting features a 90-degree elbow configuration, which is essential for routing gas or fluid lines within the compact internal architecture of welding power sources and wire feeders. The elbow design allows for a change in direction of the flow path without kinking the tubing, ensuring consistent delivery of shielding gas or coolant.

Constructed from high-grade brass, this fitting offers superior durability and resistance to corrosion compared to plastic alternatives. Brass is the material of choice for industrial fittings due to its ability to withstand temperature fluctuations and mechanical stress. The fitting connects a 1/8 NPT (National Pipe Taper) threaded port to a 0.250-inch (1/4-inch) tubing line. The NPT thread ensures a tight, leak-proof seal when properly installed, while the tubing connection is designed for quick disconnect (QDISC) functionality or secure attachment depending on the specific mating component.

Maintenance professionals and industrial technicians rely on genuine Miller parts to ensure equipment reliability. Using non-OEM fittings can lead to compatibility issues, leaks, or premature failure, potentially causing downtime in critical welding operations. This specific fitting is often utilized in the gas solenoid assembly or internal plumbing of MIG and TIG welders. Its precise machining ensures that it threads smoothly into manifolds or valves and grips the tubing securely to prevent blowouts under pressure.

When replacing fittings in industrial equipment, verifying the thread pitch and tubing diameter is crucial. The Miller 216277 simplifies this process for owners of compatible Miller machines by providing a direct replacement solution. Whether you are performing routine maintenance or repairing a damaged gas line, this brass elbow provides the quality and assurance expected from Miller Electric products.
