Hey you's guys,
I am connecting a Fire Alarm system to a new sprinkler system. The valves installed are a bit different in that the connection where the wire leads exit the valve body has a unknown female thread.
It is smaller than a 1/2" NPT so I can't use a Chase Nipple into a box for the wire splice. There was a rubber threaded hex nut already installed but I don't think it will hold up as a metal Chase Nipple.
This rubber plug appears to have a straight thread not a tapered which is also odd. The outside diameter of the threads is .790".
Does anyone know what kind of thread this might be and/or what can be used to adapt to it in order to make a secure connection of a junction box??
Sadly the instructions are skimpy on the details.
Thanks for any assist,
Les
