摘要：
A pipe fitting or coupling is used for connecting at least two pipes. The pipe fitting is basically formed of a coupling main body and a slit ring integrally formed together. The coupling main body is formed of an inner layer of good heat resisting property, an intermediate layer containing glass fibers, and an outer layer having large tensile elongation and impact strength. The slit ring is formed at an edge portion of the outer circumferential surface of the coupling main body.
