The conduit fitting may be configured to couple to an electrical mechanical tubing (EMT) often used in a fire suppression system. The conduit fitting may include an upper cylindrical section and a lower conical section. The upper cylindrical section and the lower conical section can both include a slit extending partially through the conduit fitting. ## Claims ### Claim 1 A conduit fitting configured to couple to an electrical mechanical tubing (EMT) connector within a fire suppression system, the conduit fitting comprising: an upper cylindrical section comprising a threaded receiving element configured to receive a threaded securing element of the EMT connector; and a lower conical section including a continuous inner conical surface separated by a slit, the upper cylindrical section and the lower conical section both including the slit extending partially through the conduit fitting. ### Claim 2 (depends on 1) The conduit fitting of claim 1, wherein the upper cylindrical section and the lower conical section are formed of a unibody structure. ### Claim 3 (depends on 1) The conduit fitting of claim 1, wherein the upper cylindrical section and the lower conical section are mated together via at least one of molding, welding, stamping, or extrusion. ### Claim 4 (depends on 1) The conduit fitting of claim 1, wherein the upper cylindrical section comprises a diameter dimensioned to receive at least a portion of the EMT connector. ### Claim 5 (depends on 1) The conduit fitting of claim 1, wherein the upper cylindrical section includes a top surface configured to mate to the EMT connector. ### Claim 6 (depends on 1) The conduit fitting of claim 1, wherein the lower conical section includes an inner conical surface slanted at an angle between twenty and eighty degrees. ### Claim 7 (depends on 1) The conduit fitting of claim 1, wherein the slit is configured to receive a portion of a fusible link line passing therethrough. ### Claim 8 (depends on 1) The conduit fitting of claim 1, wherein the slit includes a first slit section in the upper cylindrical section, a second slit section in the lower conical section, and an aperture located at a vertex of the lower conical section. ### Claim 9 A fire suppression system comprising: a control system including a storage container containing a fire suppression agent; a protected area including an exhaust duct and an exhaust hood, the protected area including a plurality of conduits extending from the control system; and at least one fusible link system positioned on at least one conduit of the plurality of conduits, the at least one fusible link system including an electrical mechanical tubing (EMT) connector comprising a threaded securing element; and a conduit fitting configured to couple to the EMT connector, the conduit fitting comprising: an upper cylindrical section comprising a threaded receiving element configured to receive the threaded securing element of the EMT connector; and a lower conical section including a continuous inner conical surface separated by a slit, the upper cylindrical section and the lower conical section both including the slit extending partially through the conduit fitting. ### Claim 10 (depends on 9) The fire suppression system of claim 9, wherein the upper cylindrical section and the lower conical section are formed of a unibody structure. ### Claim 11 (depends on 9) The fire suppression system of claim 9, wherein the upper cylindrical section and the lower conical section are mated together via at least one of molding, welding, stamping, or extrusion. ### Claim 12 (depends on 9) The fire suppression system of claim 9, wherein the upper cylindrical section includes a top surface configured to mate to the EMT connector. ### Claim 13 (depends on 9) The fire suppression system of claim 9, wherein the threaded receiving element is configured to receive a threaded securing element of the EMT connector. ### Claim 14 (depends on 9) The fire suppression system of claim 9, wherein the lower conical section includes an inner conical surface slanted at an angle between twenty and eighty degrees. ### Claim 15 (depends on 9) The fire suppression system of claim 9, wherein the at least one conduit of the plurality of conduits includes a fusible link line passing therethrough, wherein the slit is configured to receive a portion of the fusible link line passing therethrough. ### Claim 16 (depends on 9) The fire suppression system of claim 9, wherein the slit includes a first slit section in the upper cylindrical section, a second slit section in the lower conical section, and an aperture located at a vertex of the lower conical section. ### Claim 17 (depends on 9) The fire suppression system of claim 9, further comprising a manual pull station mechanically connected to the control system. ### Claim 18 (depends on 9) The fire suppression system of claim 9, wherein at least one conduit of the plurality of conduits comprises a series of nozzles, each nozzle configured to spray the fire suppression agent onto at least one of a cooking unit and into the exhaust duct of the protected area.
