Delavan 00135-90a1 Oil Burner Nozzle 1.35 Gph 90 Degree

Product Description

The DELAVAN 00135-90a1 is a Type A hollow-cone oil burner nozzle rated at 1.35 gallons per hour (GPH) with a 90-degree spray angle. It is designed for residential oil-fired heating systems where a hollow cone air pattern is required. The nozzle features a brass body with a steel orifice disc and an integrated sintered filter. Droplet distribution is concentrated on the outer edge of the cone, which promotes reliable ignition and low-noise combustion. It is rated for operation at 100 psi and a temperature rating of 80 degrees F. Licensed oil burner technicians are the primary installers of this component.

This nozzle is suited for residential oil burners that operate with a hollow cone air pattern and throughputs up to 10.00 GPH. The Type A hollow-cone pattern is commonly specified on burner applications where flame shape, ignition stability, and combustion noise are key performance factors. It is a direct-fit replacement nozzle used during annual burner tune-ups and combustion efficiency service calls.

Key Features

• Type A hollow-cone spray pattern concentrates droplets on the outer edge of the cone for stable ignition
• 1.35 GPH flow rate suited for residential oil burner throughput requirements up to 10.00 GPH
• 90-degree spray angle for proper flame geometry in compatible burner heads
• Brass body with steel orifice disc for durability in fuel oil service
• Sintered filter integrated into the nozzle assembly to help prevent orifice contamination
• Rated to 100 psi operating pressure per ISO 9001 applicable standard

Compatibility

Designed as an OEM-style replacement nozzle for residential oil-fired burners requiring a Type A hollow-cone pattern at 1.35 GPH and a 90-degree spray angle.

Installation Notes

Oil burner nozzle replacement should be performed by a licensed oil burner technician. Always shut down the burner and allow the fuel system to depressurize before removing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle body or electrodes during removal and installation. Nozzle replacement is typically performed as part of an annual combustion efficiency tune-up in accordance with local codes and NFPA 31 guidelines.
