|
| ●A metal-to-metal seal and an O-ring seal between stage collar body and the bottom sub make seal reliability. |
| ●A reduced length of the tool minimizes the effect of bending stresses. |
| ●The seals providing internal and external pressure integrity are housed in the stage collar body and remain |
| stationary throughout operation, minimizing chances of their being damaged. |
| ●The pressure-relief design prevents fluid trapping and compression between the opening device and the |
| closing plug during the closing phase of the tool's operation. |
| ●A reliable lock-ring locks the closing sleeve upward when in place. |
| ●Both the opening and closing sleeves lock against rotation for easy drill-out. |
| ●A minimum amount of aluminum and rubber are the only materials encountered during drill-out. |
| ●No welds are used on any portion of the tool. |
| ●Material made of tool can be up to 135ksi minimum yield, including material suitable for sour gas service. |
| ●All premium threads are available. |
