Rheem 595038a Oil Nozzle 0.75W 80 Degrees

Product Description

The RHEEM 595038a is an all-purpose oil burner nozzle designed to atomize fuel oil into a fine spray pattern for combustion in oil-fired heating systems. Rated at 0.75 gallons per hour with an 80-degree spray angle and a W (wide hollow) pattern, this nozzle meters fuel flow and shapes the flame profile at the burner head. Proper nozzle sizing directly affects combustion efficiency, heat output, and flue gas quality. Licensed oil burner technicians and HVAC service professionals install and replace this component during annual tune-ups, combustion analysis, or burner troubleshooting.

This nozzle is suited for residential and light commercial oil-fired furnaces, boilers, and water heaters that call for a 0.75 GPH flow rate at an 80-degree wide spray pattern. The all-purpose designation makes it applicable across a range of standard retention-head and conventional burner assemblies. It is typically replaced on a seasonal maintenance schedule or whenever combustion testing indicates degraded atomization, sooting, or off-spec CO2 and smoke readings.

Key Features

• 0.75 GPH flow rate for precise fuel metering in oil-fired systems
• 80-degree spray angle for broad flame pattern coverage
• W (wide hollow) pattern suits a wide range of burner head configurations
• All-purpose designation supports use across multiple burner applications
• Single-unit packaging for straightforward one-for-one replacement

Compatibility

Designed as an OEM-style replacement oil burner nozzle for oil-fired furnaces, boilers, and water heaters requiring a 0.75W 80-degree nozzle specification.

Installation Notes

Oil burner nozzle replacement should be performed by a licensed oil burner technician or qualified HVAC service professional. Shut down the burner and allow the system to cool before servicing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle adapter or electrode assembly, and follow combustion analysis procedures after installation to verify correct air-to-fuel ratio and smoke number. Dispose of the used nozzle in accordance with local regulations.
