998561 - Tweco 24CT-62-S Spray Master Nozzle | 5/8" Bore | Recessed Tip

Tweco 24CT-62-S Nozzle for Spray Master MIG Guns

The Tweco 24CT-62-S (SKU: 998561) is a premium replacement nozzle designed for the Tweco Spray Master series of MIG guns, including the MS250, MS350, and MS450 models. Engineered for professional industrial environments, this nozzle features a 5/8-inch (15.9 mm) bore, providing a balanced gas flow suitable for a wide range of welding applications. The unit is identified by the part number 24CT-62-S, where 'CT' denotes Coarse Thread and 'S' indicates the standard housing configuration with a recessed tip.

This nozzle utilizes a coarse thread design which significantly reduces the time required for changeovers compared to fine-threaded or slip-on alternatives. The threads are cut directly into the copper body, allowing for a secure mechanical connection that resists loosening during operation while remaining easy to unscrew even after exposure to heat and spatter. The nozzle is self-insulated, meaning the electrical insulation is integrated into the nozzle assembly, simplifying inventory by removing the need for a separate insulator part.

The 1/8-inch recessed tip relationship is a critical feature for welders seeking improved gas coverage. By positioning the contact tip slightly inside the nozzle, the shielding gas envelope is better established before reaching the weld pool, reducing porosity risks in drafty shop environments. Constructed from high-quality copper alloy, the 24CT-62-S offers excellent thermal conductivity, ensuring the nozzle stays cooler longer, thereby extending the service life of the consumable.
