1/2″ Upright Fire Sprinkler – 68°C Standard Response

The 1/2 inch Upright Fire Sprinkler with a 68°C temperature rating and standard response mechanism is a highly reliable fire suppression device designed for use in automatic sprinkler systems. It activates individually when the surrounding temperature reaches a critical point, releasing pressurized water to control or extinguish the fire directly at its source. This model is commonly used in commercial buildings, warehouses, industrial facilities, hotels, and retail environments. It is manufactured from high-quality brass or zinc alloy and features a 5mm glass bulb, which provides dependable thermal sensitivity in standard response applications.
