0459990129 - ESAB PSF Series Conical Gas Nozzle 16mm Flush

Optimize Your Arc with ESAB Precision

For the professional welder, the front-end consumables of your MIG gun are where the rubber meets the road. The ESAB 0459990129 Conical Flush Nozzle (16mm) is built to give you the visibility and gas coverage you need to lay down perfect beads, pass after pass. If you are running an ESAB PSF 305, 405, or 505 torch, this is the standard nozzle that likely came with your rig—and for good reason. The 16mm bore provides a wide, stable column of shielding gas, making it excellent for medium-to-heavy amperage applications where protecting the molten puddle from atmospheric contamination is non-negotiable.

The conical shape is a favorite among fabricators because it tapers towards the work, giving you a better line of sight into the joint. This is particularly helpful when welding in tight corners or tracking a fillet weld where bulky cylindrical nozzles might obscure your view. The "flush" contact tip alignment is versatile; it supports short-circuit transfer modes where you need to get close to the puddle, but it also handles spray transfer well, provided you maintain the correct stick-out. Unlike recessed nozzles that can struggle in tight spots, or protruding tip setups that lose gas coverage, the flush design is the reliable workhorse for 90% of your daily welding tasks.

Spatter buildup is the enemy of productivity. You know the frustration of stopping every few inches to bang your torch or scrape out the nozzle. While no nozzle is immune to spatter, the high-quality copper alloy used by ESAB resists spatter adhesion better than cheaper knock-offs. This means the spatter that does land is easier to remove with your welper pliers or a quick dip in nozzle gel. Keep your arc smooth, your porosity low, and your downtime to a minimum with this genuine ESAB part.

Why Welders Choose This Nozzle:

• Better Visibility: Tapered design helps you see the puddle clearly.
• Consistent Shielding: 16mm opening ensures a broad gas envelope for clean welds.
• Tough Build: Handles the heat of high-amperage welding without melting or warping.
