Aluminum Hydraulic Stage Collars

Designed for maximum flexibility in user operations, the hydraulic feature allows the tool to operate in highly deviated or horizontal wells. One design for both mechanical and hydraulic operation.

Type 680 - Hydraulic Stage Collar features two internal sleeves that shift during the stage cementing operations. The stage collar can be field set to open hydraulically at different opening pressures. This is achieved through the addition or removal of the brass shear screws from the stage cementing tool. The bottom sleeve can also be shifted open mechanically by dropping the opening dart
