Set the expansion packing (ISA-7-B) in the concave of the SUP port for expansion switches. NOTE If the detection nozzle is exposed to splashes of water or cutting oil, do not allow backflow from the detection nozzle to the switch body. Install the switch body at a position higher than the detection nozzle wherever possible.

Refer to the AR-A/AR-B/AR-D series catalog excerpt, which has been reproduced below.
The part number of the standard AR20 to AR60 round type pressure gauge is “G36-10-01,” or “G46-10-01”(for the R thread type).
For example, the part number of the AR30-03BG-A pressure gauge is “G36-10-01.”
