Black Bull™ Sealing Cups

The efficient and profitable operation of the JetStar™ casing plungers system depends on the positive seal provided by the Black Bull™ sealing cups.

These cups create a ‘no leak’ seal by contact with the inner wall of the casing, which enables the upward travel of the casing plunger on a continuous, reliable basis.

Black Bull™ sealing cups feature …

• High Strength to withstand high pressure
  
• Extreme wear resistance against steel
  
• Special flexibility to conform to irregularities in casing
  
• Constant stability to maintain form.

This performance breakthrough is the result of constant development of cup design, materials and processes.

The Black Bull™ seals have exceptional life and have proven to be tough, durable and reliable.
