PTFE Lined Sight Flow Indicators
Series FIF/PTFE

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 therefore 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 also available with flutter flow indicators. PTFE lined sight flow indicators are drilled to mate with ANSI Class 125/150 connections.
