Constructed from brass, this nozzle produces a spray pattern that is neither fully hollow nor fully solid cone, making it adaptable across a wide range of burner air patterns. At lower flow rates the spray pattern tends toward hollow cone behavior, while at higher flow rates it shifts toward solid cone. Licensed HVAC technicians and oil burner service professionals install this nozzle during routine tune-ups, burner replacements, and combustion efficiency service calls.\u003c\/p\u003e\n\u003cp\u003eThe type w nozzle is suited for oil-fired furnaces, boilers, and water heaters where spray pattern flexibility is needed. Its all-purpose design allows it to substitute for either solid or hollow cone nozzles across the 0.40 to 8.00 GPH flow range, regardless of the burner air pattern in use. This makes it a practical stocking option for service technicians who work across multiple burner brands and configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAll-purpose spray pattern functions in place of solid or hollow cone nozzles\u003c\/li\u003e\n  \u003cli\u003eRated at 0.40 GPH for precise fuel delivery at low firing rates\u003c\/li\u003e\n  \u003cli\u003eBrass construction for durability and fuel oil compatibility\u003c\/li\u003e\n  \u003cli\u003eCompatible with burner air patterns without restriction\u003c\/li\u003e\n  \u003cli\u003ePattern shifts from hollow at low GPH to solid at higher GPH across the 0.40 to 8.00 GPH range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an all-purpose oil burner nozzle suitable for use in residential and light commercial oil-fired heating appliances where a 0.40 GPH firing rate is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eOil burner nozzle replacement should be performed by a qualified oil heat technician. Shut down the burner and allow the system to cool before accessing the nozzle assembly. Use a proper nozzle wrench to avoid damage to the nozzle adapter or electrodes. Verify the new nozzle GPH rating and spray angle match the appliance manufacturer specifications before firing the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 0.40 GPH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpray Pattern\u003c\/strong\u003e: All Purpose (Type W)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DELAVAN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: type w\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DELAVAN","offers":[{"title":"Default Title","offer_id":51467548918066,"sku":"TYPE W","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313947977.jpg?v=1783906635","url":"https:\/\/voomisupply.com\/products\/delavan-type-w-brass-oil-burner-nozzle-0-40-gph","provider":"Voomi Supply","version":"1.0","type":"link"}
