PROBLEM TO BE SOLVED: To provide a resin connector excellent in barrier property against methanol and pure water, and small in the amount of extract. SOLUTION: This resin connector comprises a substantially cylindrical housing part 8 in which one end side is formed into an insertion part 6 inserted in the hose and the other end side is formed into an accommodation part 7 for accommodating an object member to be tightened inside thereof, and one set of two O-rings 9 and 10 fitted to the inside of the housing part 8. The housing part 8 is formed of a hardened resin composition having the characteristics (A) the methanol permeability at 60 deg.C is <=5 mg.mm/cm2/day, (B) the water permeability at 80 deg.C is <=2 mg.mm/cm2/day, and (C) the ion extraction in pure water at 100 deg.C is <=1 ppm. In addition, the first O-ring 9 fitted to the inner circumferential surface on the distal side in the accommodation part 7 out of the one set of two O-rings 9 and 10 is formed of the elastomer having the characteristic (D) the ion extraction in pure water at 100 deg.C is <=0.1 ppm. |
