Elsie Mfg B165 Fusible Link 165 Degrees F

Product Description

The ELSIE MFG B165 is a fusible link rated for 165 degrees F, designed to provide automatic fire protection in HVAC ductwork and damper systems. Fusible links are safety devices that hold a fire or smoke damper open during normal operation and release it when ambient temperatures reach the rated threshold, allowing the damper to close and restrict the spread of smoke or flame. The B165 is sold as a single unit and is intended for replacement service by licensed HVAC technicians or sheet metal contractors working within fire and smoke control systems.

This fusible link is suited for use in commercial and residential HVAC applications where fire dampers or combination fire/smoke dampers require a 165 degrees F release element. The 165 degrees F rating is a standard temperature rating commonly specified in duct systems serving general occupancy spaces. Installers should verify the temperature rating required by the damper manufacturer and the Authority Having Jurisdiction before selecting a replacement link.

Key Features

• 165 degrees F temperature rating triggers damper release at the rated threshold
• Single-unit selling configuration for targeted replacement service
• OEM-style fusible link design for fire and smoke damper applications
• Compact form factor suited for standard damper link brackets

Compatibility

Designed as an OEM-style replacement fusible link for fire dampers and combination fire/smoke dampers requiring a 165 degrees F rated release element.

Installation Notes

Fusible links in fire damper systems are typically installed or replaced by licensed HVAC technicians or sheet metal mechanics in accordance with NFPA 90A and local fire codes. Before servicing a damper assembly, shut down the associated air handling system and follow the damper manufacturer's reset and link-installation procedure. Never substitute a fusible link with a temperature rating different from what is specified on the damper label or the approved project documents. Replacement fusible links should be inspected and confirmed free of damage before installation.
