Westwood Products e5-598a Qb Electrode with Leads Weil-mclain Replacement

Product Description

The Westwood Products E5-598A is a QB electrode with leads designed as a direct replacement for Weil-McLain heating systems. Electrodes are a critical ignition component in oil-fired boilers and furnaces. They generate the high-voltage spark that ignites the fuel-air mixture at the burner nozzle. Without a properly functioning electrode, the burner cannot establish a flame, and the heating system will lock out on a safety fault. HVAC technicians and heating contractors rely on precision-matched replacement electrodes to restore reliable ignition performance during service calls and annual maintenance visits. The E5-598A is built to meet the specifications required by Weil-McLain equipment, making it a trusted choice for technicians who need a dependable, drop-in replacement part. QB-style electrodes are commonly used with oil burner assemblies and must be positioned at the correct angle and gap relative to the nozzle to achieve a consistent spark arc. Proper electrode alignment is essential for efficient combustion, reduced soot buildup, and long burner service life. When an oil boiler fails to fire, worn or cracked electrodes are among the first components inspected. Carbon deposits, porcelain cracks, and tip erosion are common causes of ignition failure. Replacing the electrode assembly with an OEM-matched part like the E5-598A restores the original ignition geometry. The included leads simplify the reinstallation process by providing ready-made connections to the ignition transformer. This part is well-suited for residential and light commercial oil heating systems serviced under the Weil-McLain brand. Keeping replacement electrodes on hand reduces equipment downtime and keeps heating systems running through cold-weather demand periods.
