| 20100084861 | BITE TYPE PIPE COUPLING, REFRIGERATION DEVICE, AND WATER HEATING DEVICE - In a center portion of the coupling body of a bite type pipe coupling, an insertion port for receiving a connector pipe is formed at an end that faces a coupling member. In the center portion, an insertion port is formed at an end located opposite to the end that faces the coupling member. An apparatus-side pipe is inserted into and brazed to the insertion port. A thin wall portion is formed in an outer circumferential wall portion of the entrance of the insertion port for receiving the apparatus-side pipe. The outer diameter of the thin wall portion is smaller than that of the coupling body. The thin wall portion is formed in a range extending from the entrance of the insertion port to a position that is located closer to the entrance than the inner end of the insertion port and is located in the vicinity of the inner end. | 04-08-2010 |
