Pipe joint for connecting in a sealed manner two pipe parts (10, 11) of a line for transporting a first medium (21) through surroundings containing a second medium (22), comprising two resilient sealing elements (16, 17) which lie at a distance apart, in which the two resilient sealing elements (16, 17) consist of chemically different materials, each material being suitable for use with the medium (21, 22) with which it comes into contact, and the two resilient sealing elements (16, 17) are separated from one another by a permeation- or diffusion-inhibiting layer (19). |
