Brass Bernard Slip-On Nozzles for MIG Welding

These Radnor brass nozzles are built for MIG welding guns that accept Bernard-style slip-on tips. The pack of two suits professional welders and maintenance shops that need a quick change-over during production runs. Brass construction resists spatter build-up and conducts heat away from the contact tip.

Slip-On Fit for Series 4391, 1500 and 7400 Guns

The slip-on design lets you swap nozzles without tools, reducing downtime between welds. They seat directly onto compatible Bernard gun necks, so no separate insulator or diffuser is required. This simplicity frees up bench space and keeps the consumable count low for mobile repair kits.

Two-Pack with 5/8-Inch Bore for Standard Duty

Each nozzle carries a 5/8-inch bore that handles typical gas-flow rates for mild-steel and stainless MIG work. The brass body withstands normal spatter levels but will erode faster under high-amperage pulse arcs or heavy flux-core use. Buyers needing extended life in extreme heat should evaluate copper or plated alternatives.

Questions about this item

How long does the 5/8 in bore brass nozzle last under continuous 1500 amp welding?

Brass nozzles erode faster than copper at 1500 amps; expect shorter tip life under sustained high-current runs.

Does the brass nozzle run hotter or spatter more during all-day welding?

Brass conducts heat well but spatter adheres more than on copper or plated tips, increasing cleaning frequency.

Which MIG gun models accept this Series 4391 slip-on nozzle?

Fits Bernard guns that use Series 4391, 1500 or 7400 slip-on nozzles with a 5/8 in bore.
