0457245002 - ESAB Cool 1 & Cool 2 Water Cooler Reservoir Cap

Keep Your Coolant Clean and Secure

Did you misplace the filler cap for your ESAB water cooler? It happens to the best of us. The ESAB Tank Cap (0457245002) is the exact replacement you need to get your Cool 1 or Cool 2 unit back in top shape. Running a water cooler without a cap isn't just messy—it's risky for your equipment. An open tank invites dust, dirt, and metal shavings into your coolant, which can wreak havoc on your pump and clog up your TIG or MIG torch lines. Don't risk burning out a torch or a pump over a simple plastic part.

This is a genuine ESAB part, not a generic knock-off, so you know it will thread on perfectly and seal tight. It’s made from durable plastic that stands up to the chemicals in your coolant and the rough-and-tumble environment of a welding shop. Whether your old cap got cracked, lost during a refill, or just worn out over time, this replacement swaps in seconds. Just screw it on hand-tight, and you are good to go.

Properly sealing your coolant tank also prevents spills when you are rolling your welder around the garage or shop. Keep your workspace dry and your machine running cool. This cap fits the standard OCF-2 style reservoirs found on many ESAB power source packages.
