Delavan 3/8 male nozzle adapter 28741-001

The Delavan 3/8 male nozzle adapter (SKU 28741-001) is a fitting used to connect an oil nozzle to the burner's oil line or nozzle holder. It features a male thread, typically 3/8 inch, that screws into a corresponding female port on the burner assembly. This adapter ensures a secure, leak-free mounting, and resists wear and corrosion. Proper installation prevents fuel leaks and improper alignment of the nozzle.

Parts of this type are selected primarily by thread size and type (e.g., NPT, BSP), which must match both the nozzle and the holder. Before ordering, confirm that the thread dimensions are identical to the original part. The adapter must position the nozzle correctly within the blast tube to maintain proper flame pattern and spray angle.

If the original adapter shows signs of wear or corrosion, or if the thread is damaged, it can cause fuel leaks or improper alignment of the nozzle in the combustion head. Check the adapter for thread damage or corrosion, and replace it with a unit of the same thread specification to maintain proper sealing and nozzle orientation.
