Value Collection 401-42-50 Mig Welder Bottleneck Nozzle

Product Description

The VALUE COLLECTION 401-42-50 is a brass bottleneck nozzle designed for MIG welding applications. It controls the shielding gas flow around the contact tip, directing coverage to the weld puddle and protecting the arc from atmospheric contamination. The nozzle features a 1/2 inch bore and is constructed from brass, a material chosen for its thermal conductivity and resistance to weld spatter adhesion. Installation and replacement are routine maintenance tasks performed by welders and fabrication technicians during consumable changeouts on MIG welding equipment.

This bottleneck nozzle is suited for use in fabrication shops, maintenance welding operations, and production environments where MIG process equipment is in regular service. The bottleneck profile provides improved visibility of the weld joint and is commonly used on tighter-access weld positions. The 1/2 inch bore diameter accommodates standard contact tip and gas diffuser configurations typical of 400-series MIG gun assemblies.

Key Features

• Brass construction provides good thermal performance and resists spatter buildup
• 1/2 inch bore diameter for proper gas coverage and tip clearance
• Bottleneck profile improves joint visibility in restricted weld positions
• Direct OEM-style replacement for MIG gun nozzle consumable maintenance
• Lightweight at 0.4 pounds for easy handling during consumable swaps

Compatibility

Designed as an OEM-style replacement nozzle for MIG welding guns accepting a 1/2 inch bore bottleneck nozzle configuration in the 400-series gun style.

Installation Notes

MIG nozzle replacement is performed by welding technicians and fabricators as part of routine consumable maintenance. Always power down the welder and allow the gun to cool before removing a spent nozzle. The nozzle threads or press-fits onto the gas diffuser body — inspect the diffuser and contact tip for wear at the same time. Follow the equipment manufacturer's service guidelines for proper torque and seating to maintain consistent gas coverage.
