OEM Foil Nozzle Seal and Disc for Range Guard 97054

The Range Guard 97054 is the factory-original foil nozzle seal and disc used to cover and protect Range Guard discharge nozzles. The foil seal covers the nozzle orifice to prevent grease, dust, and debris from entering the nozzle prior to system activation — ensuring clean, unobstructed agent discharge when the system fires. The foil disc is designed to rupture cleanly when the system discharges, providing no resistance to agent flow while maintaining full orifice protection during the system's standby period between inspections.

Range Guard nozzle seals serve the same critical function as nozzle caps on other kitchen fire suppression system brands — they prevent the nozzle orifice from becoming partially or fully blocked by the grease-laden aerosols that are constantly produced in active commercial kitchen environments. A blocked nozzle orifice reduces the agent discharge flow rate and alters the spray pattern, potentially leaving portions of the protected cooking surface without adequate wet chemical coverage during a real fire event. The OEM 97054 foil seal is engineered to the correct thickness and rupture strength for Range Guard nozzle geometries — ensuring it provides orifice protection without restricting discharge when activation occurs.

The 97054 is a mandatory replacement item at every semi-annual NFPA 17A and NFPA 96 inspection and at every post-discharge service event. A missing, torn, or contaminated foil nozzle seal must be replaced immediately. Available through authorized Range Guard distributors. Inspect all nozzle seals at every semi-annual service visit and document condition in the fire suppression system inspection record. The range guard fire suppression system documentation specifies the correct foil seal for each nozzle type in the Range Guard nozzle family.

Inspect all 97054 foil nozzle seals at every semi-annual NFPA 17A and NFPA 96 inspection. Check that every nozzle has its seal in place, the foil is intact with no tears or holes, and the seal is seated properly over the nozzle orifice. A missing or torn seal must be replaced immediately — a missing nozzle seal is an inspection deficiency under NFPA 96. After any system discharge, all foil nozzle seals are destroyed in the discharge and must be replaced with new 97054 seals as part of the standard post-discharge service before the system is returned to armed service. Stock the 97054 in sufficient quantity to replace all nozzle seals in the systems you service in a single visit. Document seal inspection and replacement in the fire suppression system inspection record.

Can I use a generic foil or tape to cover the nozzle instead of the 97054?

No. The 97054 is engineered to a specific rupture strength for Range Guard nozzle orifice dimensions — it must rupture cleanly at the low discharge pressure of the system activation without restricting flow. Generic foil or tape may not rupture correctly, potentially blocking the nozzle orifice during system discharge and preventing agent from reaching the cooking surface. Always use the OEM 97054 seal from authorized Range Guard distributors to maintain the system's UL 300 listing.

How often should foil nozzle seals be replaced if the system has not discharged?

Replace all 97054 foil nozzle seals at every semi-annual NFPA 17A and NFPA 96 service visit regardless of apparent condition. Grease contamination and kitchen heat can degrade foil seals over time even without visible damage. Semi-annual replacement ensures the seals are always providing full orifice protection and will rupture correctly if the system activates between service intervals.
