International shipping notice: Until further notice, we will not be receiving parts to rebuild from outside the United States. Please do not send shipments to us from outside the United States.

We provide a high-quality lower cost alternative to expensive original equipment manufacturer (OEM) replacement parts for your convertible top hydraulic system.

What We Do



We specialize in rebuilding leaking/failing convertible top hydraulics. We also manufacture hydraulic hoses and related products for models from Mercedes-Benz, BMW, Porsche, Ferrari, Bentley, Rolls-Royce, Jaguar, Maserati, Lamborghini, Aston Martin, Saab, Audi, Volkswagen, Ford, Cadillac, Chevrolet, Chrysler, and more. We’re continually expanding our product offerings. Visit our Convertible Top Cylinder Rebuild Service page to see the full range of makes and models we support.

Over time, convertible top hydraulic systems fail. We replace aged factory seals with superior hard-wearing elastomer seals. Manufactured to our specifications, our seals dramatically extend the lifespan of your rebuilt cylinders. Cabriolet Hydraulics’ seals have a high resistance to decomposition when exposed to hydraulic fluid, moisture, pressure, and extreme temperatures, ensuring long-lasting performance.

Our Latest Innovation

Cabriolet Hydraulics Cylinder Coupler, US Patent; 12,104,728

Introducing our newest product developed for easy removal and reinstallation of cylinders with factory crimped lines. Joining our Coupler family of products, our new Cylinder Coupler* is currently in production.

The Cylinder Coupler is designed to reconnect factory-installed hoses directly to our rebuilt cylinders. The new design is based on our original unique patented Hose Repair Coupler**. While our proven Hose Repair Coupler is designed to reconnect two hoses, our new Cylinder Coupler is designed to reconnect a hose directly to a cylinder.

In several convertible models, certain cylinders can be removed by cutting each hose at its factory swivel fitting. During our rebuild process, the factory swivel fittings get removed and discarded, then replaced with our Cylinder Couplers. The rebuilt cylinder ships back with our new Cylinder Couplers attached, ready to be reconnected to the hoses in the vehicle using the same quick-connect method as our patented Hose Repair Coupler.

Our Cylinder Coupler’s unique design allows independent rotation of the hose crimping body, protecting the elbow from unnecessary stress.

The Cylinder Coupler is currently in production and will be available soon.
