Abstract

A flareless-type pipe tube fitting comprises a fitting body (1), a member (2) for joining tightened to the fitting body (1), and an annular ferrule (3) formed integrally with either one of the fitting body (1) and the member (2) for joining through an annular thin-walled part. The base end of the ferrule (3) is opposite to a pressing surface (25) with a space part (34) interposed therebetween. A notch (36) for enabling easy deformation of the ferrule (3) is formed in the inner peripheral surface of the ferrule (3). The space part (34) and the notch (36) are formed by their cutting with use of a common cutting tool (51), and therefore, they have shapes corresponding to the edge of the cutting tool (51).
