Tyco TY4131 Quick Response Upright Fire Sprinkler Head – 8.0K, 155°F, Brass

Tyco TY4131 Quick Response Upright Fire Sprinkler Head – 8.0 K-Factor, 155°F, Brass

The Tyco TY4131 Upright Fire Sprinkler Head is a quick response (QR) sprinkler designed for upright installation in wet pipe fire sprinkler systems. Featuring a high-flow 8.0 K-factor and a 155°F (68°C) temperature rating, the TY4131 is engineered to deliver increased water discharge for enhanced fire control in commercial and industrial fire protection systems.

This model is finished in natural brass, making it ideal for exposed piping and ceiling installations where durability, corrosion resistance, and a metallic appearance are preferred. The quick response thermal element allows for faster activation compared to standard response sprinklers, helping improve life safety and fire suppression performance.

Performance and Design

The Tyco TY4131 is designed to provide a uniform spray pattern suitable for light to ordinary hazard occupancies. Its 8.0 K-factor allows for higher flow rates than standard 5.6K sprinklers, making it a common choice for systems requiring increased water density or reduced operating pressure.

The upright orientation allows the sprinkler to be installed above the piping, deflecting water downward to protect the hazard area below. This configuration is commonly used in warehouses, mechanical rooms, utility spaces, and other locations with exposed ceiling construction.
