The present invention provides a piping joint and integrated valve with the piping joint, which improve airtight and watertight, maintain connection firm, and keep constant quality regardless repeated user. In connecting part (110, 120) of the joint body (100), the first holes (112, 113), the second packing holes (114, 124) where the first packing rings (170, 180) are inserted, the third holes (116, 126) with a female threaded part inside conjoining the second packing rings (150, 160) and bushes (130, 140), having three holes formed three phases outward on the concentric circle. The first packing rings (170, 180) are made of silicon or Teflon(R) that is flexible and sustainable against heat. One side of said second packing rings (150, 160) contact the first packing rings (170, 180), and ground the contact parts (152, 162) stoppers (154, 164) are placed to prevent the second packing rings (150, 160) from inserting too deeply into inside of the connecting parts (110, 120) of the joint body (100) and the other sides are tapered down in a certain angle to contact the slant (137, 147) of edges or bushes (130, 140), and the tapered parts (156, 166) are equipped with projections (158, 168) inside to hold pipes (P1, P2) firm.
