Our Rebuilds & Upgrades are better and longer lasting than new OEM parts

Almost all high-end convertibles today use old technology to seal the hydraulic cylinders.

The shelf lifetime of the Polyurethane seals most frequently used is about ten years. Heat, water, and additives can even accelerate that decay!

Top Hydraulics, Inc. uses Viton™ and Teflon™-hybrid seals, as well as advanced PU seals which far exceed the OEM's requirements for rigidity, but provide between twice and ten times the service life, based on scientific test data - our warranty proves it. The standard warranty on our rebuilds is 3 years. In some cylinders, Top Hydraulics, Inc. may exchange as many as five seals that are not O-rings (and never should be), plus the hydraulic port seals where the hydraulic hoses connect.

Some of our upgrades include replacing interior parts with precisely machined ones that allow us to use seals of superior quality, material, size, and geometry. Top Hydraulics, Inc. is the largest remanufacturer of convertible top cylinders.
