An immersion type seal for a standpipe opening of a coke oven comprises a standpipe which has a top part with top opening and an encircling rim around the opening which is closed by a standpipe lid and an annular seal frame interposed between the lid and the opening. The seal frame includes a lower peripheral edge which is of spherical shape which is seated on a ring disposed over the rim of the standpipe top opening and the seal frame is advantageously adjusted on the seating ring and clamped by means of tie rods which are disposed at spaced locations around the periphery of a flange portion of the seal frame. The tie rods are clamped between flanges of a top piece of the standpipe and the standpipe itself and the flange of the seal frame. The seal frame also defines an open top trough which defines a water seal and the standpipe lid includes an annular wall portion which extends into the trough. The standpipe lid also advantageously includes an inner annular wall portion which is adapted to seat on a ledge portion of the annular sealing frame.
