Abstract

A pipe fitting comprises a fitting body with a longitudinal axis, having a pipe connection member for the sealed connection of a pipe and a thread for threadedly joining the fitting body to a connection unit, and a member on the fitting body to be driven by a tool, to which a tool for turning the fitting body about its longitudinal axis may be applied for threadedly joining the same to the connection unit. This fitting is provided with means between the tool engaging portion and the fitting body that limit the torque acting on the fitting body when the tool engaging portion is turned.
