PROBLEM TO BE SOLVED: To provide a resin tube for piping, having no risk of occlusion or fouling of the piping, excellent in fuel penetration resistance, capable of press fit-processing at a normal temperature and excellent in productivity. SOLUTION: This resin tube for piping is formed by (C) a resin composition containing (A) 100 pts.mass polyamide resin obtained by performing the condensation polymerization of xylylenediamine with adipic acid and showing 2.0-6.0 relative viscosity measured in 98% conc. sulfuric acid at 25°C and (B) 60-230 pts.mass polyamide resin consisting of a 6-nylon and/or modified 6-nylon and having≤1 GPa bending elastic modulus measured in accordance with the ASTM D790.
