173955 - Miller 173955 Replacement Water Tank Reservoir

Keep Your Cool with the Miller 173955 Tank

If you are running a water-cooled rig, you know that the cooling system is the lifeline of your torch. The Miller 173955 Water Tank is the direct replacement reservoir you need if your current tank has sprung a leak, cracked, or become too stained to read the level. Don't risk burning up an expensive TIG torch or MIG gun because of a faulty reservoir. This genuine Miller part is built to fit right the first time, so you can swap it out and get back to laying beads without worrying about puddles on the shop floor.

Water-cooled systems are amazing for high-amp welding, but they rely entirely on a sealed loop to circulate coolant effectively. A damaged tank introduces air into the lines and drops the pressure, which kills cooling efficiency fast. This replacement tank is made tough to handle the shop life, resisting vibration and the chemicals found in standard welding coolants. It’s the exact same part that came with your machine when it was new, ensuring that all your hoses and mounting brackets line up perfectly without any modification.

Why Choose OEM?
When you buy the Miller 173955, you aren't guessing with a generic bottle that might melt or leak. You are getting the factory-spec part designed for your specific Miller cooler. It’s a small investment to protect your much larger investment in your welding machine and torch package.

Installation is generally straightforward for those familiar with machine maintenance. Simply drain your old coolant (dispose of it properly!), disconnect the lines, swap the tanks, and refill with fresh Miller-approved coolant. It’s the perfect time to flush your system and start fresh. Get your machine back to 100% duty cycle capability with this essential replacement part.
