273571 - Miller 1.000 NPT Conduit Locknut Plated

Precise Miller Engineering for Reliable Connections

The Miller 273571 Nut, Conduit 1.000 Npt Pld is a specialized hardware component designed to maintain the structural integrity and operational safety of your Miller welding equipment. In the realm of industrial maintenance, even the smallest components play a pivotal role. This conduit nut is engineered with a 1.000 NPT (National Pipe Taper) thread, a standard specification that ensures a tight, leak-resistant, and mechanically secure fit when paired with corresponding conduit fittings or threaded pipe nipples. The NPT designation indicates that the threads are tapered, allowing them to form a stronger seal as they are torqued down, which is essential for equipment subjected to the rigors of heavy-duty welding environments.

Manufactured to exact OEM specifications, this nut features an Outer Diameter (OD) of 1.71 inches and a slim profile with a thickness of 0.14 inches. These dimensions are critical for applications where space is at a premium, such as inside wire feeder housings or on the back panels of power sources. The "PLD" designation refers to its plated finish, likely zinc or a similar protective coating, which provides a necessary barrier against oxidation and corrosion. In welding shops where humidity, fumes, and temperature fluctuations are common, unplated hardware can seize or rust, making future maintenance difficult. This plated nut ensures that it remains serviceable and durable over the lifespan of the machine.

Using genuine Miller parts like the 273571 ensures that you are maintaining the factory standards of your equipment. Generic hardware often lacks the precise tolerance control of OEM components, leading to loose fittings that can cause wire feeding issues, cable strain, or even electrical faults if grounding paths are compromised. Whether you are repairing a wire feeder, securing a power cable strain relief, or replacing worn hardware during a scheduled overhaul, this conduit nut provides the reliability professional technicians demand.
