Miller 058676 Replacement Brass Nut

Keep your Miller welding equipment running at peak performance with the Miller 058676 Nut, 438-20 .50Hex .75H Brs Compression Modified. This small but critical component plays a vital role in the internal plumbing and connections of your welder. Whether it is securing a shielding gas line or a coolant connection, the integrity of every fitting is essential for safety and weld quality. This genuine Miller replacement part is manufactured to the highest standards, ensuring a perfect fit that aftermarket alternatives simply cannot match.

The 058676 is a brass compression nut featuring a .438-20 thread pitch (equivalent to 7/16-20). This specific threading is designed to mate perfectly with Miller's corresponding fittings, preventing cross-threading or stripping that can occur with mismatched parts. The "Compression Modified" designation indicates that the internal geometry of the nut is tailored to specific Miller compression ferrules or seats, ensuring a gas-tight or liquid-tight seal every time. The 0.50-inch hex design allows for straightforward tightening, while the 0.75-inch height ensures the nut has sufficient grip and durability.

Brass is the material of choice for this application due to its non-sparking properties and resistance to rust and corrosion. In the demanding environment of a welding shop, where humidity and chemical exposure are common, brass components ensure long-term reliability. Replacing worn, rounded, or cracked nuts during routine maintenance is a proactive step that prevents unexpected downtime. A leaking connection can lead to erratic arc performance, contamination, or even safety hazards, making this simple replacement part an important investment in your machine's health.

This part is compatible with a variety of Miller power sources and wire feeders. Because Miller manufactures equipment with various revisions and configurations, we highly recommend checking your machine's parts manual or verifying with your serial number to confirm compatibility. By choosing the Miller 058676, you are choosing the reliability and assurance that comes with using authentic factory parts for your repairs.
