- Broad Series Compatibility — Confirmed fitment across DLW300, DLW400, DLW500, DAC7000, and DA7000 series diesel welders and generators.
- Coolant System Integrity — A correctly seated drain joint prevents uncontrolled coolant loss that can lead to overheating, engine damage, and unplanned shutdowns on the job.
- Verified Part Number — Order with confidence using Multiquip part number 1622014103 to confirm you are receiving the exact component specified for your machine.
The water drain joint provides a controlled outlet point in the engine cooling circuit, allowing coolant to be safely drained during service, winterization, or maintenance procedures. When this joint cracks, corrodes, or fails to seal properly, coolant can leak uncontrolled — raising the risk of the engine overheating during operation. Replacing a worn or damaged drain joint promptly restores the integrity of the cooling system and ensures the machine can be serviced cleanly and safely between jobs.
