Plast-O-Matic GY Flow Indicator
Plast-O-Matic® type GY flow indicators are designed to indicate the presence or clarity of high purity or corrosive liquid in a piping system, and are meant for use with ultra pure liquids or chemicals compatible with acrylic. Ends are Geon® PVC and Polypropylene. The indicator is simply threaded into a piping system and should be connected to plastic fittings. The transparent inner cylinder wall is Pyrex, a borosilicate glass that resists attack from most bases and acids with the exception of hydrofluoric acid and sodium hydroxide. The transparent outer cylinder wall is a high impact strength acrylic, ultra-violet resistant, and has an extremely high light transmission factor.
