12401433 - Tweco 24CT-75-R Nozzle 3/4 Recessed Coarse Thread (2-Pack)

Heavy-Duty Tweco MIG Nozzles for Industrial Fabrication

The Tweco 24CT-75-R Standard Nozzle is a premium consumable designed for professional welders using Tweco No. 4 and Spray Master 450 series MIG guns. This package contains two (2) high-performance nozzles, engineered to meet the rigorous demands of industrial welding environments. With a substantial 3/4-inch (19.1 mm) bore, these nozzles provide excellent shielding gas coverage, making them ideal for high-amperage applications where porosity control is critical.

One of the defining features of the 24CT-75-R is its recessed tip relationship. By positioning the contact tip deeper within the nozzle, the design offers enhanced protection against molten spatter and radiant heat. This configuration not only extends the lifespan of your contact tips but also reduces the likelihood of electrical shorts when welding in tight corners or near the workpiece surface. The recessed geometry is particularly beneficial for spray transfer modes and flux-cored applications where spatter accumulation can be a concern.

Efficiency on the production line is supported by the nozzle's coarse thread design. Unlike fine-threaded alternatives that can cross-thread or seize, the coarse threads on the 24CT series allow for quick, quarter-turn style installation and removal. This ensures that nozzle cleaning and replacement are fast, minimizing downtime. Constructed from a durable copper alloy and featuring robust insulation, these nozzles resist deformation under high heat, ensuring consistent gas flow and arc stability throughout their service life.
