An upper flange chamfer of the upper flange part is between an upper sealing element and a lower sealing element, forming an annular chamfer space is formed between the upper flange chamfer and the upper shoulder chamfer between the upper and lower sealing elements. The flange comprises an injection through hole for a filler material to be injected there through to fill the chamfer space.
