169715B - Miller 169715 Slip-On MIG Nozzle 1/2-inch (10-Pack)

Miller 169715B MIG Nozzle .500" - Bulk 10 Pack

The Miller 169715B is a premium slip-on MIG nozzle designed to deliver consistent shielding gas coverage and superior durability. This bulk pack of 10 nozzles is an essential inventory item for professional welders and fabrication shops utilizing Miller M-Series MIG guns. With a 0.500-inch (1/2") exit orifice, this nozzle is the "go-to" size for a vast majority of solid wire welding applications, providing adequate gas flow to protect the weld pool without being too bulky to fit into standard joints.

Manufactured to Miller's exacting OEM specifications, these nozzles ensure precise alignment with the contact tip and gas diffuser. This alignment is critical for maintaining a laminar gas flow, which minimizes turbulence and prevents atmospheric contamination of the weld. The nozzle body is crafted from heavy-duty copper alloy, optimized for thermal conductivity to dissipate heat rapidly. This helps keep the nozzle cooler during extended welding passes, reducing the adherence of spatter and prolonging the life of the consumable.

The slip-on interface utilizes a friction fit over the gas diffuser or nozzle adapter (depending on the gun model), often securing with a retention spring. This design eliminates the frustration of seized threads common in high-amperage applications. It allows the welder to rotate the nozzle to find the best viewing angle or remove it instantly for spatter removal. The nozzle is fully insulated to prevent short-circuiting against the base metal, a critical safety and quality feature for working in tight spaces.

Compatibility: This nozzle fits the following Miller MIG guns:

• M-10 & M-15 (Millermatic 135, 140, 175, 180)
• M-25 (Millermatic 200, 210, 212, 250, 251, 252)
• M-40 (Millermatic 300)
• Hobart H-Series guns (H-9, H-10)

Whether you are welding mild steel, stainless, or performing general repairs, the Miller 169715B provides the reliability and performance professionals demand.
