FIG. 5 is a half-sectional front view showing a conventional hose fitting. In Fig. 1, reference numeral 1 denotes a metal fitting body, on one end of which there is a socket portion 2 and a nipple portion 3 for compressing and tightening the hose end, and on the other end side there is a connecting portion 4 for connecting and fixing with other members. be.
When connecting a rubber hose and other parts using this conventional hose fitting, one end of the rubber hose is connected to the socket part 2 and the nipple part 3.
For example, the socket part 2 and the nipple part 3 are inserted between the socket part 2 and the nipple part 3.
Even if there are surface scratches, there will be no leakage when used as a hydraulic circuit.

きに液漏れの原因となる。 However, in the connection on the other end side, the joint part 4 made of a metal fitting material and another member made of a metal fitting material are metal comrades, so if there is any damage to the member that contacts the other part when connecting the joint part 4, the hydraulic circuit cannot be used. This may cause fluid leakage.

じ易い難点がある。 Now, there are a socket part 2 and a nipple part 3 on one end side of the metal fitting body 1 for crimping and connecting the hose end, and a connecting part 4 on the other end side for connecting and fixing with other parts.
Some conventional hose caps are manufactured from a relatively soft metal, such as soft carbon steel, to allow compression crimping of the hose end. For this reason, the joint is easily damaged during transportation and manufacturing processes, and when used as a hydraulic circuit, there is a problem in that fluid leaks easily occur.

る。 Therefore, attempts have been made to manufacture hose fittings from hard metals or ceramics, but in this case, the compression crimping properties with the hose end are poor and it cannot be put to practical use. In addition, attempts have been made to make the connecting part 4 on the other end of the hose cap fitting made of hard metal or ceramic, but the problem with these cases is that it is difficult to weld the fitting body to the hard metal or ceramic. be.

るのが難点である。 On the other hand, there is a ceramic coupling part 4 on the other end of the metal fitting main body 1 which has a socket part 2 and a nipple 3 on one end.
Attempts have also been made to insert and fix it, but in this case, the problem is that the fixing strength is slightly inferior because the fixing part is on one side.
本発明は、かかる点に立つて試されたものであ

The hose cap of the present invention is a hose cap that achieves both compression crimping properties and damage prevention, which were not possible with conventional metal materials alone or ceramic materials, and is also strong in strength. That is, the function of the present invention is to integrally process the outer members of the fitting main body, the socket part, the nipple part, and the coupling part with a metal material,
By inserting and fixing the ceramic inner member inside the outer member of the joint part, compression processing of the hose end at one end of the hose cap fitting is ensured, and damage prevention and strength improvement at the joint part at the other end are ensured. This is an effective improvement.
