Delavan 00135-70w1 Oil Burner Nozzle 1.35 Gph 70 Degree

Product Description

The DELAVAN 00135-70w1 is a Type W all-purpose oil burner nozzle rated at 1.35 gallons per hour (GPH) with a 70-degree spray angle. It features a brass body and steel orifice disc with a sintered filter for reliable atomization at 100 psi operating pressure. Type W nozzles produce a spray pattern that falls between hollow and solid cone, making them adaptable across a wide range of burner air patterns. Flow rates below approximately 1.5 GPH tend toward a more hollow pattern. Licensed oil burner technicians install this nozzle as part of routine annual service or combustion tune-up procedures on residential heating equipment.

This nozzle is designed for residential oil-fired heating applications. Type W all-purpose nozzles are suitable for use across a flow range of 0.40 to 8.00 GPH and can substitute for solid or hollow cone nozzles within that range regardless of burner air pattern. The 70-degree spray angle suits a broad range of residential oil burner combustion head configurations where a mid-angle atomization pattern is specified.

Key Features

• Type W all-purpose spray pattern works in place of solid or hollow cone nozzles from 0.40 to 8.00 GPH
• 1.35 GPH flow rate rated at 100 psi operating pressure
• 70-degree spray angle for mid-range combustion head compatibility
• Brass body construction with steel orifice disc for durability
• Sintered filter element helps prevent orifice contamination
• Manufactured under ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement nozzle for residential oil-fired burners requiring a 1.35 GPH, 70-degree, Type W all-purpose nozzle at 100 psi.

Installation Notes

Oil burner nozzle replacement is performed by licensed oil burner or HVAC technicians. Shut down the burner and allow the system to cool before accessing the nozzle assembly. Use a proper nozzle wrench to avoid damaging the nozzle body or adapter, and verify that fuel supply pressure matches the nozzle's rated operating pressure before startup. After installation, perform a combustion analysis to confirm proper flame pattern and efficiency.
