Standard Flange Gaskets
Style 1115 - Full Face Gaskets for 150 lb ASME/ANSI Pipe Flanges
Phelps carries large inventory of gasket material for a wide range of application in many industries including water treatment, refineries, food processing, power plants, and other industrial applications. Although 1/8" and 1/16" are the most commonly ordered thickess, we carry a wide range of thickness to choose from.
