Delavan 00050-70A1 Oil Burner Nozzles, 0.50 gph, 100 psi, 70 degrees, A, Hollow Cone

Delavan 50-70A1 Oil Burner Nozzle – 0.50 GPH, 70° Hollow Cone, Type A

The Delavan 50-70A1 Oil Burner Nozzle is a precision-machined fuel delivery component designed for consistent atomization and stable combustion in professional oil-fired heating systems. Featuring a 70° hollow cone (Type A) spray pattern, this nozzle delivers finely distributed fuel droplets concentrated on the outer perimeter of the spray for optimized flame shape and efficient fuel-air mixing. Built using Delavan’s bi-metal construction technology, it combines a brass body for effective heat dissipation and stainless steel metering components for long-term dimensional stability and wear resistance.
