ABSTRACT:
A hydraulic fitting (20,120,220,320,420,520,620,720,820) [of the type for connecting pressurized fluid-conveying members includes a tubular member (22,122,222,322,422,522,622,722,822) having opposite distal ends and defining a fluid passage (24,124,224,324,424,524,624,724,824) extending between the ends of the tubular member (22,122,222,322,422,522,622,722,822).] includes [T]threaded connection portions (26,126,226,326,426,526,626,726,826) [are provided on each end of the tubular member (22,122,222,322,422,522,622,722,822) for connecting the fitting (20,120,220,320,420,520,620,720,820) with hydraulic fluid lines and the like.], and [S]sealing portions (28,128,228,328,428,528,628,728,828) [are formed] adjacent the connecting portions (26,126,226,326,426,526,626,726,826) for perfecting a fluid-tight seal between the fitting (20,120,220,320,420,520,620,720,820) and [the] associated fluid lines. A central body member (34,134,234,334,434,534,634,734,834) is disposed about the tubular member (22,122,222,322,422,522,622,722,822) and presents one or more pairs of flats (36,136,236,336,436,536,636,736,836). The tubular member (22,122,22,322,422,522,622,722,822) and connecting portions (26,126,226,326,426,526,626,726,826) are formed from a single piece of round metal bar stock, whereas the body member (34,134,234,334,434,534,634,734,834) is formed from a molded plastic material. A method is also provided for making the fitting (20,120,220,320,420,520,620,720,820).
