Swab Cup Assembly


The Swab Cup Assembly is used below the running tool when running slotted or screen liners. The Swab Cup Assembly, coupled with the Retrievable Cementing Bushing (RCB), provides a straddle seal for setting the liner hanger packer. When the liner hanger setting ball is dropped in the tubing, this straddle isolates the pressure required to set the liner hanger packer.

  • Seals in various liner ID’s
  • Swab cups are easily field-redressable and/or configurable based on job requirements
  • Tubing threads compatible with inner string
