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.
Claims3
A pipe fitting apparatus, comprising:
- a fitting body comprising a first connecting portion having an inner threaded surface at a first end, a second connecting portion having an outer threaded portion, a ferrule seating portion on an outer surface of the fitting body adjacent to the outer threaded portion, and an inner inclined surface between a first inner cavity portion corresponding to the first connecting portion and a second inner cavity portion corresponding to the second connecting portion such that a diameter of the first inner cavity is wider than a diameter of the second inner cavity, the second connecting portion located between the first connecting portion and the ferrule seating portion;
- a force control ferrule directly on the ferrule seating portion of the fitting body;
- and
- a fixing nut comprising an inner threaded portion for rotatably engaging with the second connecting portion of the fitting body and an inclined pressure surface for abutting against the force control ferrule.
