Abstract

A downhole tool, multi-stage cementing tool, and method for cementing. The tool includes a body having a bore axially therethrough and an opening radially therethrough, and a first sleeve positioned in the bore of the body. The first sleeve has an opening radially therethrough that is axially aligned with the opening of the body when the downhole tool is in a first configuration. An inner surface of the first sleeve defines a first seat. The tool also includes a second sleeve positioned in the first sleeve, with the second sleeve being aligned with the opening of the first sleeve and preventing fluid flow therethrough when the tool is in the first configuration. The second sleeve is configured to move axially and engage the first seat of the first sleeve when the tool is in a second configuration, so as to resist relative rotation between the first and second sleeves.
