A compression type end fitting for a non-metal flexible tubing wherein the fitting includes a tubing receiving bore terminating at an internal stop shoulder with a continuing smaller diameter throughbore, a nut sub-assembly of a nut and compression sleeve having a nut receiving throughbore has a tubing reinforcing insert loosely retained within the body and nut sub-assembly when the latter are preassembled preparatory to receiving the tubing through the nut sub-assembly. The insert has a circular flange for loosely retaining the insert within the fitting body bore and has a guide end protruding outwardly of the nut sub-assembly when the latter is assembled to the fitting body to provide for an initial engagement with the tubing and for a prealigning of the tubing, insert and nut sub-assembly throughbore preparatory to pressing the tubing into the fitting and final tightening of the nut sub-assembly on to the fitting.
