FIELD: machine building.
SUBSTANCE: invention relates to machine building, particularly, to diesel engines. Proposed fuel pipe connection comprises high-pressure pipe 1 for fuel supply with connection head 2 including peripheral surface formed by spherical locating surface 3, annular projection 4 with rear surface 5 and axial hole 6, as well as nut 7 with contact surface 8 with rear surface 5 of annular projection 4 and mating part 9. In compliance with this version, freely mounted pressure sleeve with surface in contact with nut surface is used as intermediate part. Rear surface of annular projection of connecting head and surface of pressure sleeve are spherical. Centres of the spheres of the mounting surface and the surface of the annular projection of the connecting head in contact with the nut can coincide. Pressing of connecting head to mating part is provided with axial force from tightening of nut 7.
EFFECT: proposed is a fuel pipeline connection.
