Each fitting increases ease of use while decreasing the time and effort needed to connect water distribution pipe. There is no glue, soldering, or crimping needed. Simply, cut your pipe, deburr, mark the pipe approximately 1" (for proper insertion depth), install pipe to proper depth and you're done.
