The Flowturn SIGHT GLASS is made from a tough, shatter-resis- tant polycarbonate.This type of plastic has more than 30 times the impact resistance of safety glass, withstands prolonged exposure to ultraviolet rays, and can be used in temperatures ranging from -150 degrees to 165 degrees F. Acids No effect under the most common conditions of concentration and temperature Alcohol Generally compatible at low concentration and room temperature. Higher concentrations and elevated temperatures result in etching and attack evidenced by decomposition. Alkalis Generally compatible at low concentration and room temperature. Higher concentrations and elevated temperatures result in etching and attack evidenced by decomposition. Aliphatic Hydrocarbons Generally compatible. Amines Surface crystallization and chemical attack. AVOID. Aromatic Hydrocarbons Partial solvents and severe stress cracking agents. AVOID. Detergents and Cleaners Mild soap solutions are compatible. Strong alkaline materials should be avoided. Esters Cause severe crystallization. Partial solvents. AVOID. Greases and Oils Pure petroleum types generally compatible. Many additives used with them are not. Halogenated Hydrocarbons Solvents. AVOID. Ketones Cause sever crystallization and stress cracking. Partial solvents. AVOID. Silicone Oil & Greases Generally compatible up 185oF. Some contain aromatic hydrocarbons which should be avoided. CHEMICAL COMPATIBILITY * Always place the pipe wrench on the metal connections and not the sight glass itself when tightening, and never tighten or loosen under pressure. * Avoid direct contact with strong acids or chemicals such as carbon disulfide, acetone etc. * The Flowturn Sight Glass should always be installed in a “T” when used in a flow line to eliminate breaking or bending that may occur due to vibrations from a hard flowing well or the pumping unit. * Use 500PSI rated glass for storage tank drain lines only. Never use 500psi rated on flow lines, use 1000 or 1500 PSI rated glass on flow line. WARNING The following list shows the chemical classes which the Sight Glasses may be exposed to and the effects that may be experienced in oil tank applications. For other applications please advise your service and fluid type.
