208123 - Miller Coolant Recovery Tank Cap Gasket

Genuine Miller 208123 Gasket for Overflow Bottle Cap

The Miller 208123 is a specialized replacement gasket designed specifically for the overflow bottle caps found on select Miller welding equipment. As an essential component of the cooling or engine management system, this gasket ensures a hermetic seal between the coolant recovery tank and its cap. Maintaining this seal is critical for the proper operation of the coolant recovery system, allowing for the thermal expansion and contraction of coolant fluid without leakage or loss of system pressure.

Manufactured to Miller's precise Original Equipment Manufacturer (OEM) specifications, this gasket guarantees a perfect fit and superior durability compared to generic alternatives. It is constructed from high-quality, heat-resistant materials capable of withstanding the thermal cycling and chemical exposure typical of welding environments. Failure of this small component can lead to coolant loss, potential overheating, and messy leaks within the machine housing. Replacing a worn, cracked, or compressed gasket with the 208123 restores the integrity of the overflow system.

This part is commonly associated with Miller engine-driven welders and industrial water-cooling units where liquid cooling is employed. Regular inspection of cooling system components, including seals and gaskets, is recommended during routine maintenance intervals to prevent unexpected downtime and ensure the longevity of the equipment.
