Abstract
A fitting () for connecting a pipe which includes a hollow body () made in one piece, which extends in a pipe insertion direction (X) about a longitudinal axis (L). The hollow body () includes at least one pressing section (), which can be plastically deformed in a radial direction (Y) using a press tool (), which can be attached prior to pressing and which can be detached after pressing. The pressing section () includes a circumferential bead (), which projects outwardly in a radial direction, and which, on the inside, forms a groove () for accommodating a sealing ring. The pressing section () further includes at least two cutting blades (), one arranged upstream of the bead () and one arranged downstream from the bead (), relative to the pipe insertion direction (X). A sufficiently tight sealing is thus ensured, even when using a lead and nickel-free alloy.
