Delavan 1.35-70-w Oil Burner Nozzle 1.35 Gph 70 Degree Type W All Purpose

Product Description

The Delavan 1.35-70-W is an oil burner nozzle designed for residential heating systems that run on fuel oil. It delivers a flow rate of 1.35 gallons per hour at a spray angle of 70 degrees using a Type W all-purpose spray pattern. HVAC technicians and heating contractors rely on this nozzle to atomize fuel oil into a fine mist before it enters the combustion chamber. Proper atomization is critical for clean, efficient combustion. A well-matched nozzle reduces fuel waste, limits carbon buildup, and helps keep flue emissions within acceptable levels. The Delavan 1.35-70-W is built with a brass body and a steel orifice disc, giving it the durability needed for the heat and pressure conditions inside an oil burner. It carries a pressure rating of 100 PSI and a temperature rating of 80 degrees Fahrenheit, making it well-suited for standard residential oil heating applications. The 70-degree spray angle produces a wide cone pattern that distributes atomized fuel evenly across the combustion chamber, supporting stable ignition and a consistent flame. The Type W designation means the spray pattern is a solid cone, which works well in a broad range of residential oil furnaces and boilers. A sintered filter is built into the nozzle to catch fine particles before they reach the orifice, helping protect nozzle performance over time. The nozzle is manufactured under ISO 9001 quality standards, which means production processes are held to consistent quality controls. HVAC service technicians performing annual tune-ups, nozzle replacements, or burner adjustments will find this nozzle a reliable, direct-fit option for matching 1.35 GPH residential oil burner specifications. Always verify the flow rate, angle, and pattern against the original equipment manufacturer specifications before installation.
