URO 90157391500 A/C Expansion Valve

URO A/C Expansion Valve for Classic European HVAC Service

This URO A/C expansion valve is built for classic Mercedes-Benz, BMW, Porsche, and Jaguar air conditioning systems that need precise refrigerant control at the evaporator. The copper construction and internally equalized capillary tube design support stable operation across a wide range of A/C pressures and temperatures.

Key Features

• Copper construction for durable HVAC service
• Internally equalized, capillary tube design
• Manufactured to OE valve dimensions for proper clearance and fit
• Built for extreme refrigerant pressure and broad operating temperatures
• Direct replacement for a failed A/C expansion valve during system service
• Part number 90157391500 for catalog and cross-reference use

Detailed Description

When the expansion valve in an air conditioning system begins to restrict flow incorrectly, evaporator performance can drop and cabin cooling becomes inconsistent. This URO valve is engineered to restore refrigerant metering at the evaporator, helping the system return to proper cooling behavior. It is a direct-fit service part for applications such as the Mercedes-Benz 560SL, BMW 320i, and Porsche 911, along with additional classic European models listed in the fitment data. The part number 90157391500 is also useful when matching OE-style replacement requirements during HVAC repair.

This part cross-references URO (e.g., URO-000552) for the same application.

What It Helps Solve

• Weak or uneven cabin cooling
• Incorrect refrigerant metering at the evaporator
• A/C performance loss after expansion valve failure
• Temperature instability during system operation
• Restricted flow caused by a worn or damaged valve

Installation Notes and Tips

• Fits 1986-1989 Mercedes-Benz 560SL, N/A; at evaporator; flared style w/ factory rotary compressor
• Fits 1981-1985 Mercedes-Benz 380SL, N/A; at evaporator; flared style w/ factory rotary compressor
• Fits 1977-1983 BMW 320i, N/A
• Fits 1965-1983 Porsche 911, N/A
• Fits 1973-1977 Jaguar XJ6, N/A

Confirm OE valve dimensions and system configuration before installation, especially on vehicles noted with factory rotary compressor or evaporator-mounted applications. Proper A/C service practices and system evacuation are recommended before returning the vehicle to operation.

Quality Assurance

URO lists this expansion valve with guaranteed fitment, high-quality materials, and a 24 month unlimited mileage warranty. The valve is manufactured to OE dimensions to support correct clearance and straightforward installation in the intended Mercedes-Benz, BMW, Porsche, and Jaguar applications.
