13201100 - Tweco 32 Nozzle Insulator for Classic & Spray Master MIG Guns (25-Pack)

Tweco 32 Nozzle Insulator (1320-1100) - 25 Pack

The Tweco 32 Nozzle Insulator (Stock Number 1320-1100) is a critical component for maintaining the electrical integrity and performance of Tweco MIG guns. Designed specifically for the Tweco Classic Series (No. 2, No. 3, and No. 4) as well as the Spray Master Series (250, 350, and 450), this insulator serves as the barrier between the electrically live gas diffuser and the outer gas nozzle. By effectively isolating these components, the Model 32 insulator prevents accidental arcing and short circuits against the workpiece, ensuring operator safety and equipment longevity.

Manufactured from high-temperature fiberglass composite materials, the Tweco 32 insulator is engineered to withstand the intense heat and spatter typical of industrial welding environments. It is an essential part of the adjustable nozzle system found on standard Tweco guns, holding the nozzle in place while allowing for adjustment of the contact tip recess. Regular inspection and replacement of the nozzle insulator are recommended to maintain proper gas flow and prevent shielding gas turbulence caused by degraded components.

This product is supplied as a bulk package of 25 units, making it an ideal procurement choice for fabrication shops, manufacturing facilities, and maintenance departments that require consistent inventory of high-wear consumables. Using genuine Tweco parts ensures dimensional accuracy and material compatibility, reducing the risk of fitment issues that can occur with aftermarket alternatives.
