Petromax Pressure Gauge HK150/HK250/HK350/HK500 Brass

The pressure gauge is inserted into the upper part of the tank. The manometer seal ensures that the recess is sealed airtight when inserted and that there is no pressure loss. On the scale between 0 and 3 bar, the optimum operating pressure is indicated by a red mark. The pressure gauge is also equipped with a bleed screw to reduce the pressure if necessary.
