  • Product typeWelding Parts & Supplies
  • Self-insulated copper nozzle simplifies setup and reduces component count
  • Series 2137 design ensures compatibility with Tweco-style welding equipment
  • 3/8 in bore diameter provides consistent gas coverage for clean welds
  • Copper construction delivers excellent thermal conductivity and durability
  • Pack of two nozzles keeps a spare on hand for uninterrupted work

Copper Self-Insulated Nozzle Pair

This pack supplies two Tweco-compatible copper nozzles for MIG welding guns. They are built for welders who need a direct replacement tip that threads into standard Series 2137 consumable bodies. The self-insulated design simplifies changeovers on the bench or in the field.

Suits Standard Tweco Guns Not Proprietary Systems

These nozzles fit guns that accept Series 2137 threads and a 3/8 in bore. They will not work on machines that require proprietary thread patterns, insulated liners, or larger bore diameters for heavy flux-cored wire. Buyers using non-Tweco platforms should verify compatibility first.

Series 2137 Thread With 3/8 In Bore

The critical specification is the Series 2137 thread pattern combined with a 3/8 inch bore diameter. This pairing determines whether the nozzle seats correctly and delivers proper gas coverage for the wire size being used.

Questions about this item

What MIG gun series must I already have for the Series 2137 nozzle to fit?

The nozzle is made for Series 2137 guns; confirm your gun matches that series before fitting.

Will the 3/8 in bore work with the contact tips I already use on the same gun?

A 3/8 in bore accepts standard tips for that bore size; match the tip to the bore and wire diameter you run.

How can I confirm the two copper nozzles are ready for use after opening the pack?

Check both nozzles for clean, undamaged copper threads and a clear 3/8 in bore before threading onto the gun.
