The Brownfield Non-Elastomeric Sliding Sleeve is high performance, equalizing Sliding Sleeve which allows communication between the tubing and annulus for circulation or selective-zone production. When desired, the Sleeve can be shifted open or closed using standard wireline methods and a ‘B’ type OTIS or Baker shifting tool. The Sliding Sleeve is designed such that any lock profile and compatible seal bores can be specified to accept a wide range of Wireline Locks, and accessories.

The nominal working specifications for the Sliding Sleeve, in most cases, are burst, collapse, and tensile equal to the tubing, up to 325oF service temperature with a 1,500 psi maximum shifting differential.
