Bulkhead fitting device enabling slight relative movements and the absorption of forces between a conduit and a wall, and installation including at least one such bulkhead fitting device

An installation comprising:

• a wall with an orifice,
• a conduit passing through the wall via the orifice, and
• a bulkhead fitting device linking the conduit and the wall, wherein the bulkhead fitting device comprises:
• a first ring configured to be positioned about the conduit and sealingly linked to said conduit on a first face side of the wall,
• a second ring having a flat, ring-shaped sealing face configured to be oriented towards the wall on the first face side of the wall and to be pressed against a contact face of an intermediate part linked to the wall,
• an elastically deformable intermediate annular portion sealingly linking the first and second rings,
• a holding system configured to press the sealing face against the contact face to create a seal between the sealing and contact faces,
• the first and second rings and the intermediate annular portion forming a single part,
• wherein the first ring has an axis of revolution,
• wherein the intermediate part comprises a third ring comprising the contact face against which the sealing face of the second ring is pressed, a tubular middle portion linking an edge of the third ring to a fourth ring configured to sealingly link the third ring and the wall about an entirety of the orifice,
• wherein the fourth ring is offset from the third ring in a direction transverse to the axis of revolution of the first ring.
