The Amerex 3181 is a hydrostatic test adapter listed in Amerex's official fire extinguisher parts book for water, water mist, wet chemical, and foam extinguisher cylinders. It threads onto the cylinder's 1-1/2"-16 UN valve opening so a technician can connect hydrostatic test equipment to pressure-test the cylinder during periodic recertification, without needing the extinguisher's normal valve assembly installed.
