Shutgun Replacement Link Spring

This link spring restores a Shutgun fire sprinkler tool to normal operation after a fire, allowing it to act as a temporary fire sprinkler head after an accidental activation incident. Shutgun fire sprinkler tools feature a heat-sensitive metal link that detaches at temperatures over 164F (73C). This spring sits behind the link, helping the Shutgun to fall away from system piping when high temperatures indicate that a fire may be in progress.

Often, this link spring should be combined with a new fusible link, tips, and rubber pads, which may all be damaged when a fire causes the Shutgun to detach.

The Importance of Having a Shutgun

Sometimes, our fire sprinklers activate in non-fire scenarios, and this can be a big problem – especially regarding potential water damage. That’s what the Shutgun is for – a quick and easy fire sprinkler shut off tool. Without a fire sprinkler shut off tool, sprinkler discharge can only be stopped at the main valve or a local shutoff valve. Fire code may require personnel to patrol the building or even evacuate until the broken head is replaced.

Shutgun stops water damage caused by accidental fire sprinkler discharge: vandalism, human error, and industrial accidents can lead to non-fire activation, which can lead to mold, mildew, damaged carpets, and a host of other expensive issues. A Shutgun fire sprinkler shutoff device is essential for contractors, movers, painters, cleaners, or anybody else who works in close proximity to fire sprinklers.

How do I apply the attachment?

To secure this link spring to a Shutgun fire sprinkler tool:

• Make sure all parts of the worn spring and/or fusible link are removed.
• Place the spring onto the end of the shaft and slide up as far it can go.
• Slide a new fusible link onto the shaft, ensuring that the long tip rests inside the arm.
