PTFE lined sight flow indicators have been designed for visually observing the flow of
corrosive media. Except for the borosilicate glass, all wetted parts of the indicators
are lined with PTFE. These units are ideal for viewing such corrosive fluids as acids,
chlorides, sulfates, bleach solutions, solvents, and phenols.
Each model can be provided with drip tubes. The Series FIF-PTFE lined is also
available with flutter flow indicators. PTFE lined sight flow indicators are drilled to
mate with ANSI Class 125/150 connections.
