249375 - Miller 249375 Brass Tee Fitting 1/4 PTC x 1/8 NPT Swivel

Technical Overview of the Miller 249375 Brass Tee Fitting

The Miller 249375 is a specialized brass tee fitting designed for precision fluid or gas control within industrial welding equipment. Engineered to meet the rigorous standards of Miller Electric, this component features a robust brass body that provides excellent resistance to corrosion and mechanical stress. The fitting is configured as a tee, facilitating the splitting or combining of flow paths within the machine's internal piping system.

Key to its functionality are the connection interfaces. Two of the ports utilize 1/4-inch Outer Diameter (OD) Push-to-Connect (PTC) mechanisms. These push-lock fittings allow for the rapid insertion and secure retention of compatible tubing without the need for tools or hose clamps, significantly reducing maintenance time. The third port features a 1/8-inch National Pipe Taper (NPT) Male thread. A distinguishing technical feature of this threaded connection is its swivel design, which allows the fitting to be oriented correctly during installation even after the thread is tightened, preventing kinked lines and easing assembly in confined chassis spaces.

The component is rated for operation in temperatures as low as -40°F, making it suitable for equipment stored or operated in cold environments. Whether used for shielding gas distribution or coolant lines, the Miller 249375 ensures a leak-free seal and reliable performance. Technicians replacing this part should verify the tubing diameter and thread pitch to ensure compatibility with the specific Miller power source model being serviced.
