The Evolution Model EL Sliding Sleeve is a down hole device, normally screwed into the production tubing, that allows communication between the tubing and the casing.

The closing sleeve has bonded upper seals to ensure the integrity of the seals for the extended periods of time downhole. They can be of various elastomer types.

The upper sub has a selective EF landing nipple profile machined into it to allow for the proper shifting of the sleeve and to serve as a receptacle for other flow control devices such as blanking plugs and separation tools.

The Evolution Model ED-2 Shifting Tool is used to shift the EL Sliding Sleeve open and closed.  The sleeve is designed so that normal wireline activities will not open or close the sleeve inadvertently.  Upward jarring opens the sleeve and download jarring closes it.

For extended tool life, the sliding sleeve can be redressed with the Evolution EL Sliding Sleeve Redress Kit.
