This part is listed by BMW as BMW part number 32411139448 (32 41 1 139 448) and is described as BMW Power Steering Suction Hose / line, as used on 1992, 1993, 1994 and 1995 model BMW 525i sedan and wagon.
Not for cars before 7/1991 (July of 1991) production date. If your E34 525i was built before 7/91, this hydraulic power steering line will not be the correct one, but any 1992, 1993, 1994 or 1995 model is compatible.
This runs from the power steering pump to the steering rack. At either end is a hard metal line secured with a bolt and copper crush washer. The hose has extra length so the system can have more fluid capacity. Unfortunately it has a lot fittings where rubber hose meets metal line. These fittings are compression crimp-style swage ("swedge") fittings that are very common in the automotive world. These swage fittings are the most common area for PS leaks on your BMW. It's easier to replace the entire line with a new OEM or BMW part than to try and repair the line.
This PS hose is made by Rein, the original equipment manufacturer that supplies BMW on many parts. This high quality brand is a wise chose for fitment, longevity and overall value.
