SMR Mechanical Set

SMR Mechanical Set

Silver Fox “SMR” Tubing Set Cement Retainers are used for secondary cementing operations. These drillable retainers set securely in any hardness casing. A ratchet lock ring stores the setting force in the retainer. The one piece packing element and metal back up rings combine for a superior seal. The case hardened, one piece slips virtually eliminate premature setting, yet can be easily drilled out.

  • Retainer includes the use of brass shear screws on cones to allow disassembly
  • Sleeve has increased Bonded rubber and O-Ring sizes to maintain consistent Flow and Seal
  • Sleeve has inside taper matched to mandrel that does not allow collet fingers to see force when removing stinger


  • Up to 10,000psi rating
  • Sets securely in any hardness casing, including premium grades
  • Ratchet lock rings secure dynamic setting force
  • Pressure balanced sleeve valve is opened and closed by tubing manipulation from the surface for better control
  • Compact, easy running
