Detailed

 Mechanical Stage Collars have been used by operators for their special applications.
The model MC stage collar should be used with other accessories like a closing plug,
a free-fall opening device, a first stage sealing plug and a shut-off baffle.
  Features 
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.
