3/4" NPT Extension Piece for the Standard Shutgun

The Standard Shutgun comes equipped with a tip designed to plug fire sprinkler heads with a 1/2″ National Pipe Thread (NPT) thread connection. This extension piece lengthens the jaws of these fire sprinkler tools, allowing a Standard Shutgun to stop the flow of water from 3/4″ heads.

Crafted using cast aluminum and manufactured by Technicraft, the maker of the original Shutgun, this attachment stops discharge from larger-orifice pendent, upright, and sidewall heads without affecting the original emergency activation temperature of 164F (73C). This Shutgun attachment is designed for non-recessed and semi-recessed heads only. For models designed for institutional, sheared, recessed, or concealed heads, view our full selection of Shutgun tools and parts.

What is a Shutgun?

Shutgun is a fire sprinkler shut off tool originally created to fit 1/2″ sprinkler heads. This fire sprinkler stopper clamp can be attached to a sprinkler head to stop the flow of water while keeping the sprinkler head operational. It is equipped with a fusible link thermal element that activates at 164F (73C), acting as a temporary replacement for a fire sprinkler head until a code-compliant replacement is installed.

The standard Shutgun design allows for the closure of a wide range of sprinklers, including semi-recessed, pendent, horizontal sidewall, and upright fire sprinklers. Without fire sprinkler tools like these, sprinkler discharge can only be stopped from control valves at the system riser or local shutoff valves. Each Shutgun stops water damage caused by accidental fire sprinkler discharge: vandalism, human error, and industrial accidents can lead to mold, mildew, damaged carpets, and a host of other expensive issues. This fire sprinkler shutoff device is a must-have tool for contractors, movers, painters, cleaners, and anyone who works in close proximity to fire sprinklers.

How do I attach this 3/4″ NPT extension to my Shutgun?
