Abstract: In a joint mechanism as a pipe joint, an indicator ring is disposed between an end of a tightening cap and an outer wall portion of a body. The indicator ring is made up from a flat section that abuts against the body, an inclined section on an outer circumferential side of the flat section, and a protrusion formed on an outer edge portion of the inclined section. The protrusion is formed in parallel along an outer circumferential surface of the tightening cap. When the tube is connected, the inclined section is pressed by the end of the tightening cap, whereby the inclined section becomes substantially coplanar with the flat section. Concurrently, the protrusion projects toward an outer circumferential side of the inclined section.

Abstract: A fitting to be secured on pipes can be used with a number of distinct pipe materials and types. The fitting includes a nut receiving a Belleville spring washer. As the nut is tightened on threads on an end fitting, it forces the Belleville spring washer away from a relaxed position. This causes a radially inner portion of said spring washer to dig into an outer surface of the pipe, locking the Belleville spring washer, and hence the nut, on the pipe. The deformation of the washer also forces a ring against an inner seal, deforming the seal against the pipe, the nut, and the end fitting. In a second embodiment, a second washer is also deformed. The present invention provides a simple and universal method of attaching pipes to end fittings.

Abstract: A ferrule is used together with other components to couple a liquid tight fitting to flexible metal conduit. To assure secure coupling, the ferrule must be fully engaged with the flexible metal conduit. Full engagement of the ferrule is not always obtained because of carelessness, burrs, tightness or other obstructions. Even if full engagement is achieved, it is not always maintained as other parts of the fitting are assembled. The improved ferrule includes a hole which provides means for visually inspecting the engagement of the ferrule with the flexible metal conduit even after the fitting is fully assembled. The ferrule may or may not include an outer cylindrical wall for enclosing a portion of the end of the flexible metal conduit.
