Monarch Oil Burner Nozzles are high-quality atomizing nozzles designed for use in industrial, commercial, and residential oil burner systems. Manufactured to strict quality standards, each nozzle is individually tested to ensure accurate fuel flow, spray pattern consistency, and dependable burner performance.

The nozzles are suitable for fuels with viscosities up to 5 cSt, with special versions available for heavier oils up to 13 cSt. They are available in multiple spray patterns including solid cone, hollow cone, semi-solid cone, narrow angle, and heavy oil configurations, allowing users to select the ideal nozzle for their specific burner requirements.

Each Monarch nozzle is marked with its flow rate, spray angle, spray pattern series, and product identification for easy selection and maintenance.
