The Jerguson Series 51 Liquid Level Gage is a specially designed instrument capable of withstanding high pressures.  The one-piece chamber is machined out of solid bar stock carbon steel or stainless steel as specified.  It is drilled lengthwise and crosswise at each port leaving tie-bars in between to resist deflection under pressure.  Viton® “O” rings that seal each port are unaffected by most liquids that cause deterioration in rubber.  The “O” rings are seated in recessed circular channels to assure proper seating action.
