Abstract
A resin tube fitting has: a body with an outer sleeve; an inner ring including an insert portion insertable into the outer sleeve to contact the outer sleeve radially, and a press-in portion configured to be pressed into a longitudinal end of the tube; and a union nut configured to be engageable with the body. The body and the inner ring are made of resin, which has a property of contracting in response to change in ambient temperature. A radial contraction rate of the outer sleeve of the body is designed to be higher by 0.09% or more than that of the insert portion of the inner ring.
