Range Guard Disc Cap for LPR Nozzle 120026

The Range Guard 120026 is the disc cap for the Range Guard LPR (Low Pressure Range) nozzle used in Range Guard kitchen fire suppression systems. The disc cap covers the LPR nozzle orifice during normal kitchen operation. Protecting the precision discharge opening from grease buildup, food particles, and debris that are constantly circulating in the air above commercial cooking equipment. Without the disc cap in place, grease can accumulate inside the nozzle tip and partially or fully block the orifice, preventing the Karbaloy wet chemical agent from discharging correctly when the system fires.

The LPR nozzle disc cap is a specifically designed cover for the LPR nozzle geometry. It's not a generic cap that fits any Range Guard nozzle. The 120026 is sized and shaped for the LPR nozzle's specific orifice profile and must rupture cleanly at the low pressure of Range Guard system discharge without restricting agent flow. Using a generic cap or the wrong Range Guard disc cap risks either not covering the orifice correctly (leaving it unprotected) or not rupturing cleanly on discharge (blocking agent flow). The OEM 120026 is engineered to the correct rupture characteristics for the LPR nozzle.

Replace the 120026 disc cap at every semi-annual NFPA 17A and NFPA 96 inspection and after every system discharge. A missing, torn, or grease-soaked disc cap is an immediate inspection deficiency. Available through authorized Range Guard distributors. Document disc cap inspection and replacement in the fire suppression system inspection record.

At every semi-annual NFPA 17A and NFPA 96 inspection, verify the 120026 disc cap is present on every LPR nozzle, intact with no tears or holes, and properly seated over the nozzle orifice. Remove each cap and inspect the nozzle orifice underneath for grease or debris. A partially blocked orifice must be professionally cleaned or the nozzle replaced before the system passes inspection. Install fresh 120026 disc caps on all LPR nozzles after inspection. After any system discharge, all disc caps are destroyed and must be replaced with new 120026 caps as part of the post-discharge service. Document in the fire suppression system inspection record.

Is the 120026 the same as the Range Guard foil nozzle seal (97054)?

No. The 97054 is the foil nozzle seal used on standard Range Guard nozzles. The 120026 is the specific disc cap for the LPR (Low Pressure Range) nozzle, which has a different orifice geometry and cap design. Using the wrong cap type for the wrong nozzle risks either an incomplete orifice seal or a cap that doesn't rupture correctly on discharge. Always use the cap designed for the specific nozzle type in your system.

How often should I replace the 120026 even if it looks clean?

Replace at every semi-annual NFPA 17A and NFPA 96 inspection regardless of appearance. Grease contamination in the kitchen environment degrades disc cap materials over time a cap that looks intact may have absorbed enough grease to change its rupture characteristics. Semi-annual replacement ensures the cap always provides reliable orifice protection and correct rupture performance.
