Set of 12 Upgraded Hydraulic Lines/Hoses for '03-'07 Audi A4 Convertible

New product

Top Hydraulics proprietary hoses replace all of the OEM hoses on your complete convertible top with far superior material. The OEM hoses are rated at 3,000 psi; Top Hydraulics' hoses are rated at a burst pressure of 23,200 psi!



We highly recommend replacing all hoses at the same time, once you see the first deterioration on your original hoses. There will be no pressure reducer needed with these hoses!

Top Hydraulics replaces the OEM hose material on your complete convertible top hose assembly with far superior material. The OEM hoses are rated at an operating pressure of 3,000 psi; Top Hydraulics manufactures these hoses with a rated burst pressure rating of 23,200 psi. The Jaguar system pressure peaks between 1,500 and 1,600 psi.

The outer diameter (OD) of the front hoses is smaller than that of the OEM hoses, and much smaller than that of brake hoses. (Some small shops try to manufacture convertible top lines out of brake hoses with braided stainless jackets). The smaller OD makes the installation easier, while not posing any compromise in performance. The lines are clearly labeled on each end (telling you where they connect to), and they come with new o-rings. The hose material is sourced in Germany, the hoses are assembled in the US, and these hoses will not crumble apart like your original ones.
