This listing includes two vintage industrial selector guides. The first is an ITT Grinnell Selector for Forged Steel Flanges and Carbon Steel Welding Fittings, providing detailed specifications for various pipe sizes from 1/2" to 24". It covers dimensions for flanges (O.D., thickness, bolt holes, bolt sizes) and welding fittings (elbows, reducers, tees, crosses, caps). The second item is a Smith Closet Fitting Selector Guide, copyrighted 1966 by J. R. Smith Mfg. Co., Piscataway, N. J. This guide assists in determining nipple length for standard "C" dimension and identifying left or right hand closet fittings for various plumbing configurations. Both are valuable tools for collectors, engineers, or anyone working with industrial piping and plumbing systems. These are reference guides, not actual fittings.
