Delavan .75 70A Oil Burner Nozzle 0.75 GPH 70° Hollow Spray Type A

Delavan .75x70A Oil Burner Nozzle

0.75 GPH | 70° Spray Angle | Type A Hollow Cone
REM# 4M525

The Delavan .75x70A Type A oil burner nozzle is engineered for precise atomization and stable flame formation in oil heating systems.

With a 0.75 GPH firing rate and 70-degree spray angle, this nozzle produces a hollow cone (Type A) spray pattern that delivers fine droplets primarily to the outer edge of the spray pattern. This design enhances ignition stability and is especially well suited for flame retention burners and applications requiring consistent peripheral fuel distribution.

🔧 Specifications:
• Flow Rate: 0.75 GPH
• Spray Angle: 70°
• Spray Pattern: Type A (Hollow Cone)
• MFG#: .75X70A
• REM#: 4M525
• Precision machined brass construction

🔥 Type A Hollow Spray Pattern:
Distributes droplets to the periphery of the spray cone, creating a very stable flame and excellent ignition characteristics — particularly effective in fractional GPH applications.

✅ Applications:
• Residential oil furnaces
• Oil boilers
• Flame retention burners
• Annual maintenance replacements
• High-viscosity oil applications

⚙ Compatibility:
Commonly used with Beckett, Carlin, Wayne, Riello, and other oil burner assemblies.
Always verify required GPH and spray angle before purchase.

Ideal for HVAC contractors and oil heat service technicians.
