276878 - Miller 3/8 Inch Brass Barbed to 3/8 Inch NPT Female Hose Adapter

Technical Overview of the Miller 276878 Brass Hose Fitting

The Miller 276878 is a high-quality brass hose fitting designed to facilitate secure connections between flexible tubing and rigid piping systems. Engineered for industrial reliability, this fitting features a 3/8-inch barbed end on one side and a 3/8-inch National Pipe Taper (NPT) female thread on the other. The barbed design is specifically optimized to grip the inner diameter of 3/8-inch hoses, providing a tight seal when used in conjunction with appropriate hose clamps or crimp ferrules. This ensures minimal risk of leakage, which is critical in applications involving shielding gas, coolant, or compressed air.

Constructed from solid brass, this component offers excellent resistance to corrosion and mechanical wear, making it suitable for harsh shop environments where exposure to moisture and various gases is common. Brass is the material of choice for these applications due to its non-sparking properties and durability under fluctuating pressures. The NPT female threading allows for universal compatibility with standard 3/8-inch male NPT pipe nipples, valves, or manifold outlets, providing versatility in system configuration and repair.

This OEM part ensures fitment and performance standards consistent with Miller Electric's reputation for quality. It is an essential component for maintenance and repair operations (MRO) looking to maintain the integrity of welding machine coolant systems, gas delivery lines, or pneumatic tool setups. Proper installation requires ensuring the hose is fully seated over the barbs and secured with a clamp to prevent blow-off under pressure.

Whether you are fabricating a custom gas distribution manifold or repairing a damaged coolant line on a power source, the Miller 276878 provides the structural integrity and precise dimensions required for professional results. Its robust design withstands the rigors of daily industrial use, ensuring long-term service life and operational safety.
