Pro-source 4323R Mig Welder Nozzle Insulator

Product Description

The PRO-SOURCE 4323R is a replacement nozzle insulator designed for MIG welding guns. It fits between the contact tip and the gas nozzle, providing electrical isolation and protecting the nozzle from heat and spatter. This component is a standard wear item in MIG welding setups and is replaced during routine gun maintenance. It accommodates wire outside diameters from 0.030 inches up to 0.094 inches, making it suitable for a range of wire sizes commonly used in light to medium MIG welding applications. Installation and replacement are handled by welding technicians and maintenance personnel as part of regular gun servicing.

This nozzle insulator is used in MIG welding gun assemblies across a variety of welding applications. It is suited for shop environments, fabrication facilities, and field repair scenarios where MIG gun components require routine replacement. Compatible with wire sizes in the 0.030 to 0.094 inch outside diameter range, it fits into typical MIG gun nozzle assemblies where a standard insulator is specified. Sold individually, with a minimum order quantity of 2 units.

Key Features

• Accommodates minimum wire outside diameter of 0.030 inches
• Accommodates maximum wire outside diameter of 0.094 inches
• Functions as a nozzle insulator to provide electrical isolation between contact tip and gas nozzle
• Compact form factor at 0.89 inches in length
• Direct replacement for worn or damaged MIG gun nozzle insulators

Compatibility

Designed as an OEM-style replacement nozzle insulator for MIG welding guns that accept wire outside diameters between 0.030 and 0.094 inches.

Installation Notes

Installation is performed by a qualified welder or welding equipment technician. Always disconnect the welding gun from the power source and allow the gun to cool completely before handling nozzle components. Remove the gas nozzle and contact tip to access the insulator, then replace the worn insulator and reassemble in reverse order. Inspect the contact tip and nozzle for wear whenever replacing the insulator.
