Every welder knows that the front end of the gun takes the most abuse. If your nozzle insulator is cracked, burned, or missing, you're asking for trouble—from erratic gas coverage to shocking your nozzle against the table. This Bernard Style 4423R Nozzle Insulator is the direct replacement you need for your 400 Amp rig. Whether you are running a Q-Gun, S-Gun, or T-Gun, this insulator snaps right into place and gets you back under the hood fast.
Why pay premium prices for a part that is going to get cooked eventually anyway? This generic replacement is made from tough, heat-resistant material that stands up to the spatter and heat of heavy fabrication just like the original. It holds your nozzle tight and keeps the juice where it belongs—at the wire, not arcing out the side of your cup. It works perfectly with standard Centerfire™ consumables, making it a no-brainer for your toolbox.
Don't let a $5 part shut down your production. Keep a few of these 4423R insulators on hand. They are easy to swap out: just pull the nozzle, pop the old insulator off, and slide this one on. It seats firmly, ensuring your shielding gas flows smoothly and your nozzle stays electrically neutral. Perfect for structural steel, heavy manufacturing, and any shop running high-amperage Bernard gear.
