Cylindrical Sheathed Sight Flow Indicator

860-F 4000-S

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.

 

Features:

• 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
