12401897 - Tweco Velocity VNET-37F Extended Taper MIG Nozzle 3/8 Inch Flush (2-Pack)

Tweco Velocity VNET-37F Extended Taper Nozzle (Pack of 2)

The Tweco 1240-1897 (Model VNET-37F) is a premium MIG welding nozzle designed for the revolutionary Velocity consumable system. Sold in a convenient pack of two, these nozzles are engineered to meet the rigorous demands of industrial fabrication environments where efficiency and part longevity are critical. The VNET-37F features an extended taper geometry, specifically developed to provide welders with better access to complex joints and tight corners that standard cylindrical or bottleneck nozzles cannot reach effectively.

This nozzle utilizes a 3/8-inch (9.5 mm) bore, which is ideal for applications requiring precise gas coverage, typically with smaller diameter wires or in short-circuit transfer modes. The "Flush" designation indicates that the contact tip sits flush with the nozzle exit, offering a balanced combination of gas shielding and puddle visibility. This configuration is widely used in general fabrication where the operator needs to maintain a consistent stick-out while ensuring the arc remains protected from atmospheric contamination.

A key benefit of the Velocity platform is its threadless design. Unlike traditional nozzles that screw onto a diffuser and often seize due to spatter and heat expansion, the Velocity nozzle pushes on and pulls off easily. This design integrates the contact tip holder into the nozzle itself, reducing the number of consumable parts required in inventory. The solid copper construction ensures maximum thermal conductivity, keeping the front-end consumables cooler and extending their service life. For procurement managers and shop supervisors, the VNET-37F represents a high-performance solution that reduces downtime associated with consumable changes and maintenance.
