Description
The Reliable Model J168 Automatic sprinkler utilizes the center strut solder in compression principle of construction. The fusible alloy is captured in the cylinder of the solder capsule by a stainless steel ball. When the fusible alloy melts, the ball moves into the cylinder allowing the cylinder to separate from the center strut. When this happens, the lever is released to spring free from the sprinkler so that all operating parts clear the waterway allowing the deflector to distribute the discharging water in a hemispherical pattern. The Reliable Model J168, 16.8 K-factor sprinklers were tested in full scale fire tests to qualify them for the protection of rack and high piled storage.
