OVERVIEW

Keep Your MIG Gun Performing Like New

Is your MIG gun sputtering or showing signs of porosity despite having gas flow? The culprit might be a worn-out seal at the back of your torch. The Tweco 2000-2040 O-Ring is the specific replacement part needed for the conduit stop assembly in your Tweco MIG gun. Over time, heat and compression can cause these rubber O-rings to crack or flatten, leading to subtle gas leaks that waste expensive shielding gas and compromise your weld quality.

Don't let a ten-cent part ruin a hundred-dollar weld. This pack of 10 ensures you always have a fresh O-ring handy whenever you change a liner or service your gun. Installing a new O-ring is a quick and simple step that restores the gas seal integrity of your equipment. It is compatible with various Tweco gun models that utilize the standard conduit stop mechanism.

Professional welders know that preventative maintenance is key to consistent results. By replacing your conduit stop O-ring regularly, you ensure smooth gas flow and protect your liner assembly. Pick up a pack today and add it to your repair kit so you are never caught off guard by a leaking gun.

Key Benefits

  • Perfect Fit: Designed specifically for Tweco hardware.
