A fluid proof hinge has a first hinge part and a second hinge part connected by a metal pin. The first hinge part has an integral flange of an elastomeric material adjacent to the hinge area, the flange extends along the length of the hinge and protrudes towards the second hinge part. The second hinge part has a receiving portion for the flange also extending along the length of the hinge. The two hinge parts are connected together by the metal pin so that the flange of the first hinge part contacts the receiving portion of the second hinge part to provide a fluid seal on one side of the hinge. The fluid-proof hinge is useful in many applications, specifically as a hinge for a fluid flow control plate in a fluid passageway such as in a passageway from a feed box to a sieve bend.
