Gemini Cylinder Kits-Surface Mount

The listed Gemini Cylinder Seal Kits are for SURFACE MOUNTED LIFTS. The same cylinder part numbers are not necessarily made by the same vendors and parts are not interchangeable. The most common builders of Lift Cylindera are:

  • BEST
  • MASSEY-FERGUSON/PACOMA (MF)
  • TEXAS HYDRAULIC (TH)

Most cylinders will be marked on the housing with some form of identification indicating the manufacturer. It is important to identify the maker of your cylinder so you order the correct seal kit..
