FastBlock Top Drive Solution

Pat. Pending

CFI’s robust and long-lasting FastBlock Top Drive Solution gives you excellent performance, and lets you focus on drilling without worrying if your manifold will fail you.

Durability & Longevity

The Oilfield demands rugged equipment and fragile aluminum-based manifolds just won’t stand up to the harsh requirement of drilling operations.

Machining a top drive manifold out of steel instead of aluminum will give you the strong and dependable control solution that drilling demands.

For a durable and constant solution, CFI’s FastBlock Top Drive Solution incorporates these factors:

  • Machined out of zinc-nickel ductile iron block and more durable than the standard aluminum version.
  • Steel grants the FastBlock enhanced resistance to the washouts associated with aluminum manifolds.
  • Using a steel-based block greatly reduces the risk of accidentally stripping a port and ruining the manifold.

Avoid Manifold Failures

Many OEMs build manifolds out of aluminum to make for a cheaper and lighter manifold as it is much easier to machine the softer, more malleable metal. But cutting corners does come with steep tradeoffs in manifold durability and longevity.

  • Here are some issues you may be experiencing:
  • Aluminum manifolds arise from exposure to constant high flow applications as fluids erode the soft internals of the manifold block, resulting in washouts.
  • With steel being much harder than aluminum, overtightened steel screws, bolts, and fittings can easily strip the manifold’s port threading, a non-repairable issue that ruins the manifold.
  • Impacts and vibrations from top drive operation can result in stress fractures or chipping and wear along the corners in an aluminum manifold, further reducing its longevity and functionality.


All these issues will result in a ruined manifold block as the system’s internal structure is too worn to maintain the correct flow rates and the system can no longer do what it is meant to.


Superior Performance & Testing

The FastBlock Top Drive Solution is designed to exceed the requirements of the standard Top Drive Manifold. This system is populated with explosion proof solenoid valves to meet the needs of top drive fluid control. In addition, each system is thoroughly tested on CFI’s instrument test stand to ensure quality and performance.

Staying With CFI’s FastBlock Top Drive Solution

“We had always used the aluminum manifold from the OEM for our top drives. The blocks were always washing out and had to be replaced, so we decided to try CFI’s ductile iron FastBlock Top Drive Solution. We’ve had several FastBlocks installed for a couple of years and there is no sign of wear, so we’re sticking with the FastBlock.”
