4491 - Bernard Style 4491 Brass MIG Nozzle Assembly, 3/4" Bore, 400A (10-Pack)

Keep Your Arc Smooth with Bernard Style 4491 Nozzles

Every welder knows that a clogged or damaged nozzle can ruin a perfect bead. With this 10-pack of Bernard Style 4491 Brass Nozzles, you can ensure your MIG gun is always ready to lay down high-quality welds. Designed as a direct replacement for the standard Bernard 4491, these nozzles are built to fit your trusty Q-Gun or S-Gun perfectly. The 3/4-inch bore is the "big mouth" of nozzles, giving you a wide umbrella of shielding gas that is absolutely necessary when you are cranking the heat up to 400 amps or welding out of position where gas coverage can be tricky.

Why brass? Brass nozzles are the workhorses of the industry. They hold up exceptionally well against the heat and abuse of daily fabrication work. While spatter is inevitable, these brass nozzles are tough enough to be cleaned repeatedly, yet affordable enough to toss when they've finally seen too much action. The integrated insulator inside the shell keeps you safe and protects your equipment from shorting out against the base metal, a feature that is vital when working in tight corners or complex fixtures.

Buying in a pack of 10 just makes sense. Running out of consumables in the middle of a job is a headache you don't need. Whether you are running a busy fabrication shop, repairing heavy equipment, or managing a production line, having a box of fresh nozzles on the shelf means you can swap out a spatter-filled cone in seconds and get back to burning wire. These nozzles pair directly with your existing 4435 gas diffusers, so there's no need to change your setup—just plug, play, and weld.
