This Delevan oil burner nozzle is a must-have for anyone looking to improve their heating system. With many variations of size, this nozzle is designed to fit a wide range of burners. Made by the trusted brand Delavan, you can be sure of high-quality and reliable performance.

The DOF is delevan's del-o-flo type which is just an upgraded version of type A and B. Even less chance of clogging and a finer spray. Highly recommended for trailer furnaces especially due to most of those not having an oil filter to begin with. If there is a DOF type in the size you use, it's worth the extra money for sure.  Thank you for your business!

Type A is Hollow

Type B is Solid

Type W is Semi-Solid
