Delavan 00100-70A1 Oil Burner Nozzles, 1 gph, 100 psi, 70 degrees, A, Hollow Cone

Delavan 100-70A1 Oil Burner Nozzle – 1.00 GPH, 70° Hollow Cone, Type A

The Delavan 100-70A1 Oil Burner Nozzle is a precision-engineered fuel delivery component designed to provide accurate atomization and consistent combustion performance in oil-fired heating systems. Featuring a hollow cone (Type A) spray pattern with a 70° angle, this nozzle produces a finely distributed spray for efficient flame development in burners requiring light, evenly dispersed combustion. Manufactured using Delavan’s advanced bi-metal construction, the brass body and stainless steel metering elements ensure long service life, stable fuel flow, and superior heat transfer to prevent fouling or residue buildup.
