PURPOSE: To reliably interconnect plastic pipes even when a distance between two ends is a little longer or shorter than a predetermined size, to have excellent pressure resistance and heat resistance, and to dissolve a problem on a smell and increase of a cost by providing a curve part deviated from the same axis and semirigidity and flexibility on a whole, and be used for feed water and feed hot water. CONSTITUTION: A plastic pipe 1 for connection has an arcuate curve part 2 deviated leftward from the same axis X and is semirigid and has flexibility on a whole. Rounding of an inner curve of the curve part 2 is L/4 or less. Couplings 4 are previously attached to two end parts of a straight line part 3 on the same axis X. A plastic pipe 1 for connection is located within a distance L between the ends of couplings 21 of a faucet 10 for a water line and feed water pipe 20. A distance A between two ends of the couplings 4 is longer than the distance L and by shortening it by an amount equivalent to a distance (a), the distance is reduced to a value equal to the distance L. The linear distance A between the two ends of the plastic pipe 1 for connection which is manufactured and to which the couplings 4 are previously attached is adjustable in the direction of an arrow mark 1. |
