Weil-mclain 672619133662 Wtgo Tankless Water Heater Coil with Gasket Replacement 590-921-612

Product Description

The Weil-McLain 672619133662 is a replacement tankless water heater coil with gasket designed for use with Weil-McLain WTGO series boilers. This coil is a direct OEM replacement part, also known by the part number 590-921-612, and is built to restore reliable domestic hot water production in hydronic heating systems. Weil-McLain is a trusted name in the commercial and residential heating industry, known for producing cast iron and steel boilers that serve homes, apartment buildings, and light commercial facilities across North America. The WTGO series boilers use an internal tankless coil to heat domestic water on demand by passing cold water through a copper coil that is submerged in the boiler water. When the coil wears out, corrodes, or develops a leak, hot water delivery stops and the entire system loses efficiency. Replacing the coil with this genuine Weil-McLain unit restores full function without requiring a new boiler. HVAC technicians and plumbers working on Weil-McLain boiler service calls rely on OEM coil replacements like this one to ensure a proper fit and long service life. The included gasket ensures a watertight seal at installation, reducing the chance of leaks at the coil flange. This part is essential for any service professional maintaining older Weil-McLain WTGO boilers in residential or light commercial settings. Keeping this part on hand reduces downtime and callbacks on boiler service jobs. Correct installation requires draining the boiler, removing the old coil flange, installing the new coil with the provided gasket, and refilling the system. Always follow the manufacturer service manual during replacement to ensure proper torque and sealing.
