ChemTite® Ethylene™ FLO-VU® Sight Flow Indicator, PTFE and Glass Wetted Surfaces

The ChemTite® Ethylene™ FLO-VU® Sight Flow Indicator has a Lexan® outer safety shield with an unobstructed 360° view to protect the glass from external damage and to provide scatter protection (two options: 360L PFA/PTFE Lined and 360M Unlined). The FLO-VU 360L sight glass: 1" through 12" diameter, featuring a full 360° unobstructed view with the high temperature and near-universal corrosion resistance of PTFE.The unique PTFE/Viton®* seal design is an envelope-type gasket which provides a secure, bubble-tight seal even in applications with extreme thermal cycling.
