Copper Tweco Nozzle Pair

This two-pack supplies replacement copper nozzles built to the Tweco coarse-thread pattern. They suit welders who need a direct swap for worn tips on compatible MIG guns. Buyers using fine-thread or metric-thread guns cannot use these parts.

5/8 Inch Bore Diameter

The critical fitment figure is the 5/8 inch bore, which sets the gas-coverage envelope and wire clearance for the gun. Match this dimension to the original nozzle before ordering; a different bore will change shielding performance.

Thread-On Installation

Each nozzle screws onto the diffuser by hand, so no special tools are required. Cross-threading is the most common issue — start the threads squarely and stop if resistance feels uneven. The Proposition 65 notice applies to the copper alloy content.

Questions about this item

What does the 5/8 inch bore diameter mean for gas coverage on this nozzle?

The 5/8 inch bore creates a large gas envelope around the weld pool, which helps shield the molten metal during high-deposition passes.

How does the coarse-threaded Tweco connection affect torch fitment?

The coarse-threaded Tweco-style connection threads directly onto compatible Tweco or Tweco-style MIG guns without adapters.

What clearance is needed to install these copper nozzles on a MIG gun?

Each nozzle measures to standard Tweco dimensions, so they fit existing gun bodies and contact-tip recesses without modification.
