The Viking VK458 K7.4 Residential Pendent Fire Sprinkler is engineered for reliable, fast-response fire suppression in modern residential environments. Designed for pendent ceiling installations in wet pipe fire sprinkler systems, this component ensures efficient water distribution directly below the unit while maintaining a low-profile aesthetic for new construction or retrofitting projects.
This sprinkler satisfies critical life safety design parameters governed by NFPA 13 standards for residential occupancies. Its thermal activation mechanism and hydraulic discharge characteristics comply with stringent fire protection codes to ensure rapid control of residential fires.
- Torque-Assist Technology: Reduces installation effort, allowing the sprinkler to seat securely on the first attempt for a leak-free seal without wrenches or thread sealants when paired with compatible InstaSeal fittings.
- K-Factor Performance: Features a 7.4 K-factor that delivers a balanced water flow rate, optimizing available water supplies for hydraulically designed systems.
- Thermosensitive Glass Bulb: Utilizes a 3mm heat-sensitive liquid-filled bulb designed to expand and shatter at a precise temperature rating for quick activation.
- Corrosion-Resistant Coatings: Available with specialized finishes, including UL-Listed Electroless Nickel PTFE (ENT) coating, to withstand humidity and moisture-prone areas like basements and bathrooms.
- Compact Pendent Profile: Low-profile design disperses water effectively while blending into residential ceilings.
