Pipe sealing profile that is designed to be made into a sealing ring that can be fitted to a spigot end of a pipe or into a socket of a pipe and has a cross-section having the following features: * a compressible sealing section that slopes upwards from a first, so-called front end of the cross-section to a first height at the rear, where that part of the pipe sealing profile is described as the front part of the pipe sealing profile that, if a pipe sealing profile has been made into a sealing ring and has been fitted to the spigot end or into the socket of the pipe, is designed to first come into contact with an adjacent pipe when two pipes are joined together, and where directional information such as "upwards/top" and "downwards/bottom" apply only to a specific section of the circumference of a sealing ring that has been fitted to a spigot end or into a socket of a pipe * and a support shoulder, that is arranged behind the sealing section and in use extends as far as a second, lower height than the sealing section * in such a way that the support shoulder, when a load that acts from the top to the bottom is applied to the pipe sealing profile, limits the compression of the sealing section, characterised in that the support shoulder of the pipe sealing profile that has been made into a sealing ring and has been fitted to the spigot end or into the socket of the pipe can be folded from a vertical stand-by position to a horizontally aligned use position in which it extends at a lower height than the sealing section. * a compressible sealing section that slopes upwards from a first, so-called front end of the cross-section to a first height at the rear, where that part of the pipe sealing profile is described as the front part of the pipe sealing profile that, if a pipe sealing profile has been made into a sealing ring and has been fitted to the spigot end or into the socket of the pipe, is designed to first come into contact with an adjacent pipe when two pipes are joined together, and where directional information such as "upwards/top" and "downwards/bottom" apply only to a specific section of the circumference of a sealing ring that has been fitted to a spigot end or into a socket of a pipe that slopes upwards from a first, so-called front end of the cross-section to a first height at the rear, where that part of the pipe sealing profile is described as the front part of the pipe sealing profile that, if a pipe sealing profile has been made into a sealing ring and has been fitted to the spigot end or into the socket of the pipe, is designed to first come into contact with an adjacent pipe when two pipes are joined together, and where directional information such as "upwards/top" and "downwards/bottom" apply only to a specific section of the circumference of a sealing ring that has been fitted to a spigot end or into a socket of a pipe * and a support shoulder, that is arranged behind the sealing section and in use extends as far as a second, lower height than the sealing section * in such a way that the support shoulder, when a load that acts from the top to the bottom is applied to the pipe sealing profile, limits the compression of the sealing section,
