Jacoby-Tarbox Sheathed Tubular sight flow indicators allow for greater visibility than bulls-eye styles. These units include cylindrical glass similar to tubular models with the addition of a body to protect the glass and help isolate the unit from pipeline stresses.
• Increased visibility with cylinder protection from rigid, non-wetted body
• Pressure ratings are 150 psig (10.3 Bar) or less (varies by size)
• Stuffing box seal eliminates direct and loading of glass
