A combustor arrangement comprising: a fuel injector ; and a seal arranged around the fuel injector and having an upstream end and a downstream end , the seal comprising: an annular body at least partially abutting the fuel injector , the annular body extending circumferentially about a central axis (A1, A4) and extending axially along the central axis (A1, A4) from the upstream end to the downstream end , the annular body comprising: a flange radially extending from the outer surface of the annular body at the upstream end ; an inner surface facing the fuel injector , the inner surface axially extending from the upstream end to the downstream end ; an outer surface radially spaced apart from the inner surface relative to the central axis (A1, A4) and facing away from the fuel injector , the outer surface axially extending from the upstream end to the downstream end ; and a plurality of slots disposed on the inner surface and circumferentially spaced apart from each other relative to the central axis (A1, A4), each slot axially extending at least partially from the downstream end to the upstream end , wherein each slot is disposed in fluid contact across its maximum length (L2-1, L2-2, L2-3, L2-4) with the fuel injector ; the combustor arrangement being characterised in that the outer surface has a substantially uniform diameter (D3, D4) along the central axis (A1, A4), wherein the seal does not include a flared portion at the downstream end . a fuel injector ; and a seal arranged around the fuel injector and having an upstream end and a downstream end , the seal comprising: an annular body at least partially abutting the fuel injector , the annular body extending circumferentially about a central axis (A1, A4) and extending axially along the central axis (A1, A4) from the upstream end to the downstream end , the annular body comprising: a flange radially extending from the outer surface of the annular body at the upstream end ; an inner surface facing the fuel injector , the inner surface axially extending from the upstream end to the downstream end ; an outer surface radially spaced apart from the inner surface relative to the central axis (A1, A4) and facing away from the fuel injector , the outer surface axially extending from the upstream end to the downstream end ; and a plurality of slots disposed on the inner surface and circumferentially spaced apart from each other relative to the central axis (A1, A4), each slot axially extending at least partially from the downstream end to the upstream end , wherein each slot is disposed in fluid contact across its maximum length (L2-1, L2-2, L2-3, L2-4) with the fuel injector ; a flange radially extending from the outer surface of the annular body at the upstream end ; an inner surface facing the fuel injector , the inner surface axially extending from the upstream end to the downstream end ; an outer surface radially spaced apart from the inner surface relative to the central axis (A1, A4) and facing away from the fuel injector , the outer surface axially extending from the upstream end to the downstream end ; and a plurality of slots disposed on the inner surface and circumferentially spaced apart from each other relative to the central axis (A1, A4), each slot axially extending at least partially from the downstream end to the upstream end , wherein each slot is disposed in fluid contact across its maximum length (L2-1, L2-2, L2-3, L2-4) with the fuel injector ; <EOS>
