Aqua-Hot WPX-886-41A Diesel Injector Nozzle Replacement Part

The Aqua-Hot WPX-886-41A is a genuine OEM replacement injector nozzle designed for use with Aqua-Hot hydronic heating systems. The injector nozzle is a critical combustion component responsible for atomizing diesel fuel into a fine spray pattern, enabling efficient and consistent ignition within the burner assembly.

Aqua-Hot hydronic heating systems are widely used in RVs, motorhomes, and coaches to provide radiant floor heating, engine pre-heat, and domestic hot water — all from a single diesel-fired unit. Keeping the injector nozzle in good condition is essential for reliable system performance, fuel efficiency, and proper combustion.

Regular replacement of the injector nozzle is recommended as part of routine Aqua-Hot system maintenance to prevent hard starts, sooting, and inefficient fuel burn. Always refer to your Aqua-Hot system's service manual for the correct nozzle specification and replacement interval.
