Delavan 00120-70A1 Oil Burner Nozzles, 1.20 gph, 100 psi, 70 degrees, A, Hollow Cone

Delavan 120-70A1 Oil Burner Nozzle – 1.20 GPH, 70° Hollow Cone, Type A

The Delavan 120-70A1 Oil Burner Nozzle is a precision-engineered fuel delivery component designed for efficient atomization and consistent combustion in oil-fired heating systems. Featuring a 70° hollow cone (Type A) spray pattern, this nozzle provides a finely distributed, peripheral fuel spray ideal for burners requiring light, evenly mixed combustion. The bi-metal construction — combining a brass body for heat transfer and stainless steel metering components for precision — ensures dimensional accuracy, durability, and consistent flow performance under continuous operating conditions.
