12201301 - Tweco 22T-37-SS Threaded MIG Nozzle 3/8" Bore (Pack of 2)

Reliable Gas Coverage with Tweco Threaded Nozzles

When consistency is key in your welding fabrication, the Tweco 22T-37-SS threaded nozzle is a go-to choice for operators using Tweco #2 or Spray Master platforms. Unlike slip-on nozzles that can be adjusted—sometimes inadvertently—this threaded version locks into place. This ensures that your contact tip recess remains exactly where the manufacturer intended, providing predictable gas coverage and arc characteristics every time you pull the trigger. It’s the perfect solution for production environments where repeatability is critical.

The 3/8-inch bore size is particularly useful for detail work. If you are welding in corners, tight fillets, or on automotive sheet metal, the narrower profile allows you to see the puddle better and get the gas exactly where it needs to be without wasting consumables. The concentrated gas cone is excellent for maintaining shielding integrity in draftier shop conditions or when using lower flow rates to save on gas costs.

Durability is built-in with Tweco's high-quality copper alloy construction. These nozzles handle the heat of day-to-day welding and clean up easily when spatter does accumulate. The self-insulated design adds a layer of safety, protecting your equipment from short circuits during tight maneuvering. Sold as a pack of two, this set ensures you have a backup ready to go, keeping your arc on and your downtime low.
