Delavan 40X60W Oil Burner Nozzle 0.40 Gph 60 Degree

Product Description

The DELAVAN 40X60W is a semi-solid spray oil burner nozzle rated at 0.40 gallons per hour (GPH) with a 60-degree spray angle. It is designed for smaller-capacity residential and light-commercial oil burners where consistent atomization and clean combustion are critical. The nozzle body is constructed of brass with a stainless-steel orifice, providing reliable metering and heat resistance over extended service cycles. Licensed oil burner technicians and HVAC service professionals install this nozzle as a standard maintenance item during annual tune-ups or combustion troubleshooting calls.

The 40X60W is suited for low-output oil burner applications where a flexible, balanced spray pattern is needed to adapt to varying air flows. The semi-solid (All-Purpose) spray classification makes it a versatile choice for burners where neither a solid nor a hollow cone pattern is specifically required. Its compact dimensions — 1.625 inches in length and 0.75 inches outer diameter — fit the standard nozzle port found on most residential oil burner assemblies. The 9/16-24 UNEF thread engagement is the common standard for oil burner nozzle adapters and retention assemblies.

Key Features

• 0.40 GPH flow rate for precise fuel delivery in low-output burner applications
• 60-degree semi-solid spray angle for balanced atomization across varying air flows
• Brass body construction with stainless-steel orifice for heat resistance and accurate metering
• 9/16-24 UNEF thread pattern matches standard oil burner nozzle adapter fittings

Compatibility

Designed as an OEM-style replacement nozzle for residential and light-commercial oil burners requiring a 0.40 GPH semi-solid spray at a 60-degree angle with 9/16-24 UNEF thread engagement.

Installation Notes

Installation should be performed by a licensed oil burner technician or qualified HVAC service professional. Always shut down the burner and de-energize the unit before removing or installing the nozzle. Use a proper nozzle wrench to avoid distorting the hex body or damaging the orifice seat. After installation, verify combustion performance with a flue-gas analyzer to confirm proper CO2, O2, and smoke readings per applicable service standards.
