When choosing fuel oil burner nozzles, select models that fit your burner type, optimize spray pattern, and resist heat and residue buildup. The top picks below are ideal for common residential and light commercial oil-fired systems, with clear guidance on who each nozzle suits best.
| Product | Best For | Key Benefit |
|---|---|---|
| MorningRo 2 Pcs Solid Oil Burner Nozzle | Brass-friendly burners needing robust spray | 80 degree solid spray; durable brass construction |
| MorningRo 2 Pcs Hollow Oil Burner Nozzle | Uniform hollow-cone spray for efficient combustion | 80 degree hollow spray; brass durability |
| 6060A Oil Burner Nozzle for Delavan | Residential or small commercial boilers needing replacement | 60 degree hollow cone; versatile 0.60 GPH |
| 3/4″ NPT Automatic Fuel Nozzle with Hook | Gasoline, diesel, biodiesel mixes for pump setups | Three-speed padlock; wide fuel compatibility |
| MorningRo 2 Pcs Hollow Oil Burner Nozzle (0.65-80 A) | Brass-brass robust option for 0.65 GHP systems | 80 degree hollow spray; durable brass |
MorningRo 2 Pcs Solid Oil Burner Nozzle

Best for burners that benefit from a durable brass solid-spray nozzle. Each package includes two 80-degree nozzles rated at 0.75 GHP. Brass construction offers rust resistance and longevity, making this a strong, long-term replacement option for oil furnaces and burner parts. The solid spray design helps achieve a steady, focused flame and may reduce varnish buildup compared with less robust options.
Who this is for: ideal for homeowners upgrading aging brass nozzles in residential oil furnaces or compact boilers. Why selected: robust brass, 80-degree pattern, and two-nozzle package offer reliable replacement and easy installation. Caution: ensure your burner head threads match 0.75 GHP specifications to avoid misfit or spray issues.
MorningRo Hollow Burner Nozzle

Best if you need a hollow-cone pattern for improved atomization and cleaner combustion. The 80-degree design favors a balanced flame in mid-size oil burners. The brass construction supports heat tolerance and long service life. Consider this option when replacing a hollow-nozzle in an older system to restore spray characteristics. Caution: verify the nozzle thread size and GPH match your burner’s requirements to prevent misfit.
6060A Delavan Replacement Nozzle

Best for installations requiring a straightforward 60-degree hollow-cone pattern. Suitable for both residential and small commercial oil-fired units. The 0.60 GPH rating supports moderate heat output. Choose this if your system benefits from a balanced spray with reliable flow. Limitation: ensure compatibility with Delavan fittings and verify thread size before purchase.
3/4″ NPT Automatic Fuel Nozzle

Best for mixed-fuel setups and larger flow needs, including biodiesel blends up to B20. The 9-16 GPM range supports higher output, with a hook for easy handling. Use this if your system requires a robust pump-style nozzle. Limitation: not all automotive pump handles accept all 3/4″ NPT configurations; confirm compatibility with your fueling system before purchase.
MorningRo Hollow Oil Burner Nozzle 0.65-80 A

Better for burners that benefit from a hollow spray pattern at 0.65 GHP. Built from heavy brass for durability and resistance to cracking. The 80-degree hollow spray promotes finer atomization, which can improve combustion efficiency and reduce buildup on the nozzle surface. Choose this if your system previously used hollow-nozzle designs. Caution: verify 0.65 GHP compatibility with your burner’s fuel pressure requirements.
Buying Guide
What nozzle pattern should I choose?
Open or hollow-cone patterns offer broader spray dispersion, which can improve mixing in some burners. Solid sprays tend to focus fuel more tightly, which can be beneficial for high-heat furnaces. Match the pattern to your burner’s throat size and combustion chamber.
Why brass nozzles?
Brass nozzles provide good heat conduction, resistance to varnish buildup, and long service life in typical fuel oils. They are commonly preferred for residential and light commercial systems because of durability and predictable spray characteristics.
How important is GPH and angle?
GPH (gallons per hour) and spray angle influence flame temperature and efficiency. A higher GPH means more fuel flow; ensure your system’s control and pump can support it. The angle (60°, 80°, etc.) affects spray coverage inside the combustion chamber. Use manufacturer guidance for best fit.
What should I check before buying?
- Thread size and connection type (NPT) to fit your burner head
- Compatibility with fuel type and additives (diesel, biodiesel blends, etc.)
- Pattern type and GHP rating that match your system specifications
- Material durability and resistance to heat and varnish buildup
Installation considerations
Turn off the burner and isolate fuel lines before replacement. Use the correct wrench to avoid cross-threading and ensure a snug, leak-free fit. After installation, perform a careful startup check for any leaks and ensure the flame is stable and within safe operating limits.
Additional options to consider
Keep spare nozzles in compatible patterns and GPH values to support routine maintenance and seasonal adjustments. For mixed fuel systems, verify nozzle compatibility with biodiesel blends and potential lubricants used in your burner.
FAQ
- Q: How do I know which nozzle angle to pick? A: Choose based on your burner chamber size and the recommended spray pattern for optimal combustion.
- Q: Are brass nozzles better than stainless steel? A: Brass offers good heat conduction and is common for home systems; stainless can be more corrosion-resistant but may be less forgiving in some fuels.
- Q: Can I reuse an old nozzle’s mounting hardware? A: It’s best to use new seals and verify compatibility to avoid leaks.
- Q: What does 0.75 GHP mean? A: It indicates the nozzle’s fuel flow rate at a standard operating pressure, guiding match with burner capacity.
- Q: Do I need a professional for nozzle replacement? A: If you are not confident with fuel systems, consult a technician to ensure safety and proper setup.
