Abstract
A pipe fitting apparatus provides easy locking with an appropriate torque for which the possibility of breakage and leakage has been eliminated by being easily configured in a manner that the locking of the pipe fitting apparatus used to connect pipes is performed with an appropriate torque. The pipe fitting apparatus has a fitting body, a force control ferrule, and a fixing nut. The fitting body has a first connecting portion with an inner threaded surface, a second connecting portion having an outer threaded portion, and a ferrule seating portion where the force control ferrule is provided. The fixing nut has an inner threaded portion for engaging with the second connecting portion of the fitting body and an inclined pressure surface for abutting against the force control ferrule.
