<p>PROBLEM TO BE SOLVED: To provide a bathtub piping connection apparatus wherein in a connection fitment for a partition wall leakage of supply hot water or return hot water is eliminated and a labor of mounting the connection fitment on the partition wall is sharply reduced, and for making thinner the partition wall of a bath room the mounting is facilitated and airtightness is maintained. SOLUTION: There is provided a flanged connection tube 10 where a flange 111 is formed over a one opening 110. In the connection tube, a male screw 112 is formed in a tube outer peripheral surface up to the other opening 113 with two parallel flat plane sections 114, 115 opposing on the male screw 112 being cut to insert a water flow tube 40 into a tube inner peripheral surface. Further, in the connection tube, there are provided packings 13, 14, 15, 16 fitted from the outside to the male screw 112 of the connection tube 10, a nut 20 where a female screw 121 threaded to the male screw 112, a water flow tube tightening fitment 30 where a female section 310 threaded to the male screw 112 and no female section 313 in the inner peripheral surface, and a ring shaped protrusion section 33 in the inner peripheral surface, ring shaped packings 31, 32, and a water flow tube 40 that communicates between the bathtub and a heating boiler.</p> |
