169732 - Miller M-25 MIG Gun Hex Jam Nut

Miller 169732 Replacement Jam Nut for M-25 Goosenecks

Keep your Miller M-25 MIG gun in top operating condition with the Miller 169732 Jam Nut Hex. This small but vital component plays a major role in the functionality of your welding torch. Located at the base of the gooseneck, this jam nut is responsible for locking the neck tube firmly into the gun body or handle assembly. It is compatible with the standard M-25 guns found on popular power sources such as the Millermatic 200, 210, 250, 252, and 300 series.

Welding operators know that a loose neck is more than just an annoyance; it is a quality issue. Movement in the neck can interrupt the shielding gas flow, leading to weld defects, and can cause resistance heating at the connection point, potentially damaging the gun handle. The Miller 169732 features precision threading to match the M-25 neck tube, allowing for a tight, secure installation. Its hex-head profile ensures you can apply the necessary torque to prevent loosening during long welding shifts.

Installation and Maintenance:
Replacing the jam nut is a straightforward maintenance task. Simply remove the old nut, inspect the threads on the gooseneck for damage, and thread on the new 169732 nut. Tighten it against the gun body to lock the neck at your desired angle. Regular inspection of this connection is recommended as part of a preventative maintenance schedule for all MIG equipment.
