Claim:
1. A water seat for use in a fire suppression sprinkler movable between an inactive position and an active position comprising: a generally polygonal guiding surface, wherein the polygonal guiding surface is in limited contact with the sprinkler, such that the water seat slides relative to the sprinkler when a corrosion residue is present within the sprinkler; a sealing surface adjacent the polygonal guiding surface, wherein the sealing surface forms a line contact seal with the sprinkler when the water seat is in an active position; and a guiding portion adjacent the sealing surface and opposite the polygonal guiding surface, the guiding portion being generally conical in shape such that the guiding portion and the guiding surface retain the water seat in an orientation generally parallel to the sprinkler when the water seat moves from an inactive to an active position.
