19972 - ESAB Water Cooler Pump Inlet Strainer Screen

Keep Your Cool with the ESAB 19972 Coolant Pump Strainer

If you run a water-cooled TIG or MIG setup, you know that your water cooler is the unsung hero of your welding rig. It keeps your torch cool, your hands comfortable, and your consumables lasting longer. But like any plumbing system, it needs to stay clean to work right. The ESAB 19972 Strainer - Coolant Pump is a small but mighty part that keeps your water cooler healthy. It sits on the intake side of your pump, catching any gunk, sludge, or debris floating in your tank before it can get sucked into the pump gears.

Why is this important? Because even a small piece of debris can wreck a pump impeller or clog the tiny passages in your welding torch head. If your coolant stops flowing, your torch can overheat in seconds, melting the power cable or destroying the head—a mistake that costs hundreds of dollars. This simple strainer is cheap insurance against that disaster. It’s a genuine ESAB part, meaning it’s built to fit perfectly in ESAB and compatible L-TEC coolers without leaking or restricting the flow you need for high-amp welding.

Maintenance is easy. Whenever you flush your coolant tank (which you should do regularly!), take a moment to check the strainer. If it’s looking clogged or beat up, swap it out with a fresh 19972. It’s designed to handle the chemical additives in welding coolants without falling apart. Don't risk your expensive equipment on a clogged line or a burnt-out pump. Keeping a spare strainer on the shelf is a smart move for any serious welder.

Whether you are a professional fabricator running a busy shop or a dedicated hobbyist with a high-end TIG machine, taking care of your cooling system is key to consistent welds. A smooth-running cooler means a steady arc and no interruptions. The ESAB 19972 Strainer ensures that your coolant stays flowing and your focus stays on the puddle, not on a flashing temperature warning light.
