Legacy ColorConnex A72440C-2PK 1/4" MNPT ColorConnex Type C Blue Plug (2 Pack)

The ColorConnex patented color code system allows for easy, color-to-color matching of couplers and plugs among the standard pneumatic interchanges. It also solves the problem of potential crossing and contaminating of different air lines. By using color to dedicate your different air lines, a lubricated line will never be used for a dry line application as long as your couplers and plugs match.
