ABSTRACT:
A pipe joint is provided wherein quick joints assembly are installable in two ports and in a fluid pressure apparatus such as a solenoid transfer valve as in the prior art, while joints with a female thread are interchangeable with the guide joints so as not to rotate even when male screw members for piping are screwed in. The quick joints and the joints with a female thread are interchangeably installed in a fluid pressure apparatus in which two ports are switched and supplied with a pressurized fluid. Although the quick joints and the joints with a female thread can be installed as in the prior art, the joints with a female thread are integrally connected and fixed between the quick joints and the joints with a female thread via a connection member so as not to rotate even when male screw members for piping are screwed in.
