Delavan 1/8 short nozzle adapter 28736-001

The Delavan 1/8 short nozzle adapter (SKU 28736-001) is an oil nozzle component used to connect an oil nozzle to the oil supply line in a burner. It sits between the nozzle and the nozzle holder or oil pipe, positioning the nozzle correctly within the combustion head. This short adapter is designed for applications where space is limited or where a standard-length nozzle would misalign the nozzle tip. The adapter does not affect spray pattern or flow rate.

When replacing an adapter of this type, ensure the thread size at both the nozzle end and the line end, as well as the overall length, match the original part. This maintains the nozzle tip's correct position relative to the air diffuser and combustion head. Compare these dimensions against the part being removed before ordering.

An incorrect or worn adapter can shift the nozzle, causing the flame to sit improperly. This may lead to flame impingement, sooting, or poor ignition. Check the adapter's thread fit and length if these symptoms occur.
