Consumables - Cups and Tips Connectivity

Extend Your Reach and Save Barrel Tip Threads

Not only can tip extenders extend the reach of your gun, but they also protect the threaded end of your barrel from damage. Some extenders are stackable and some are not – see below to determine. Adapters allow you to change the output rating on your guns by changing the contact tip and gas cup configuration to a “beefier” tip & cup configuration. View Connectivity Guide for Water Cooled configuration.
