A gasket (1, 1', 1") for sealing a compartment between two members (3, 4), one fixed and the other rotating, so as to prevent the passage of lubricant from a first ambient to a second ambient arranged on opposite sides of said compartment, and to at least hinder the passage of external contaminants from said second ambient to said first ambient; said gasket (1, 1', 1") having an annular configuration about a middle axis and having a first and a second axial opposite end (7, 8), adapted to be arranged, in use, facing said first and second ambient (5, 6), respectively; said gasket (1, 1', 1'') comprising: - a first support ring, in particular made of rigid material, preferably metallic, having a first annular fixing portion, adapted to be connected, in use, to a first of said members (3, 4); - a second support ring, in particular made of rigid material, preferably metallic, having a second annular fixing portion radially more external than said first fixing portion and adapted to be connected, in use, to a second of said members (3, 4); - a first annular elastomeric element carried by the first support ring and defining at least a first annular sealing lip cooperating with contact with said second fixing portion of said second support ring to counter, in use, the passage of external contaminants from said second ambient to said first ambient; - a second annular elastomeric element carried by the second support ring and defining at least a second annular sealing lip cooperating with contact with the first fixing portion of said first support ring to counter, in use, the passage of lubricant from said first ambient to said second ambient; and - an annular wiper member distinct from the first elastomeric element and connected to said first elastomeric element; wherein said second support ring is formed in one single piece, wherein said annular wiper member has a wiping portion (20, 32) cooperating with contact with said second fixing portion of said second support ring to counter, in use, the passage of external contaminants from said second ambient to said first sealing lip; wherein said first support ring comprises an annular radial portion overhangingly extending towards said second fixing portion of said second support ring starting from said first fixing portion and covered, at least partially, by said first elastomeric element on the side facing the second axial end of the gasket (1, 1', 1"); and wherein said wiper member is fixed, in particular by gluing, to the part of said first elastomeric element covering said radial portion of said first support ring; characterized in that said wiper member comprises: - a third support ring made of metallic rigid material and directly fixed to the part of said first elastomeric element covering said radial portion of said first support ring; and - an annular contact element carried by said third support ring, defining said wiping portion (20, 32) and made of polyurethane or elastomeric material. - a first support ring, in particular made of rigid material, preferably metallic, having a first annular fixing portion, adapted to be connected, in use, to a first of said members (3, 4); - a second support ring, in particular made of rigid material, preferably metallic, having a second annular fixing portion radially more external than said first fixing portion and adapted to be connected, in use, to a second of said members (3, 4); - a first annular elastomeric element carried by the first support ring and defining at least a first annular sealing lip cooperating with contact with said second fixing portion of said second support ring to counter, in use, the passage of external contaminants from said second ambient to said first ambient; - a second annular elastomeric element carried by the second support ring and defining at least a second annular sealing lip cooperating with contact with the first fixing portion of said first support ring to counter, in use, the passage of lubricant from said first ambient to said second ambient; and - an annular wiper member distinct from the first elastomeric element and connected to said first elastomeric element; - a third support ring made of metallic rigid material and directly fixed to the part of said first elastomeric element covering said radial portion of said first support ring; and - an annular contact element carried by said third support ring, defining said wiping portion (20, 32) and made of polyurethane or elastomeric material.
