B21 B20 B19 B18 B17 B16 B15 B14 B13 B12 B11 B10 AIR-LINE COUPLERS APPLICATION Couplings incorporate valves in both the body and nipple halfs to prevent fluid loss when the coupling is disconnected. These couplings are normally referred to as ‘‘Hydraulic Couplings’’ but they are used extensively with other media where fluid loss on disconnect is objectionable. DOUBLE SHUT-OFF BRASS SLEEVE APPLICATION Lincoln Long Stem Series Couplings interchange with Lincoln’s ‘‘Long Stem’’ series couplings. Couplings feature a full opening tubular cage for maximum flow and built-in sleeve guard to minimize accidental disconnect. Available only in 1/4’’ body size. LINCOLN LONG STEM PART NO. SIZE (IN.)
