It combines a machined aluminum head with a galvanized steel mounting bracket and an epoxy-coated disposable spin-on filter element. A built-in filter restriction indicator alerts service technicians when the element is loaded and due for replacement. The unit supports a maximum firing rate of 10 gallons per hour and filters fuel to 10 microns, protecting downstream components such as fuel pumps and nozzles from particulate contamination. The 3\/8-inch NPT inlet and outlet connections fit standard oil supply line fittings. The B100 BIOGasket construction makes this assembly compatible with biodiesel blends up to B100.\u003c\/p\u003e\n\u003cp\u003eThe 1603 is suited for single-pipe and two-pipe fuel oil supply systems serving residential oil burners and small commercial heating equipment. It installs on the oil supply line between the tank and the burner fuel unit. The galvanized bracket mounts in an up or down orientation to accommodate different installation configurations. Licensed oil burner technicians and HVAC service professionals install this filter during annual tune-ups or as a direct replacement for failing or clogged inline oil filters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMachined aluminum head with 3\/8-inch NPT inlet and outlet ports\u003c\/li\u003e\n  \u003cli\u003eBuilt-in filter restriction indicator signals when element replacement is needed\u003c\/li\u003e\n  \u003cli\u003eEpoxy-coated disposable spin-on filter element rated to 10 microns\u003c\/li\u003e\n  \u003cli\u003eB100 BIOGasket for compatibility with biodiesel fuel blends up to 100 percent\u003c\/li\u003e\n  \u003cli\u003eGalvanized mounting bracket supports up and down installation positions\u003c\/li\u003e\n  \u003cli\u003e500 square inches of filtering area with a flow rate of 45 gallons per hour\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement spin-on fuel oil filter for residential and light commercial oil-fired heating systems using 3\/8-inch NPT supply line connections and requiring 10-micron filtration.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed oil burner technician or qualified HVAC service professional.
