BMW A/C O-Ring Seal, Part 64508390601

This URO A/C O-ring is a direct-fit sealing component for BMW HVAC service and repair. It is used to replace hardened or cracked line seals that can lead to refrigerant loss and reduced cooling performance. Part number 64508390601 is built to OE-style dimensions for a proper seal at A/C fittings and components.

Key Features

  • OE-style o-ring profile and durometer for proper sealing
  • High-quality material resists refrigerant and lubricant exposure
  • Built to handle temperature cycling in automotive A/C systems
  • Direct replacement for leaking or deteriorated HVAC line seals
  • Guaranteed fitment for select BMW applications

Detailed Description

URO 64508390601 is an A/C O-ring designed for BMW HVAC sealing points where refrigerant lines connect to system components. When an original seal hardens, cracks, or flattens, the result can be refrigerant seepage and weaker cabin cooling. This replacement seal restores the connection with an OE-style profile and material hardness chosen to match the application.

Compatible BMW applications include 2006-2008 BMW 550i, 650i, 750i, and 750Li; 2003-2008 BMW 760Li; 2006-2007 BMW 525i; 2001-2007 BMW 530i; 2001-2006 BMW 325Ci, 325i, 325xi, 330Ci, 330i, and 330xi; and additional BMW models across 1982-2008. This part number 64508390601 also cross-references URO-010435 for the same application.

Common Repair Uses

  • Refrigerant leaks at A/C line connections
  • Loss of cabin cooling performance
  • Cracked, flattened, or hardened original o-rings
  • Service repairs on BMW HVAC fittings and components
  • Seal replacement during A/C line or component maintenance

Installation Notes and Tips

Inspect the mating surfaces before installation and replace any damaged or corroded fittings. Clean the connection area thoroughly, then lubricate the new o-ring with the correct refrigerant oil before assembly to help prevent pinching and improve sealing. Verify the system is evacuated and recharged according to BMW A/C service procedures after repair.

Quality Assurance

URO 64508390601 is backed by a 24-month unlimited mileage warranty. The seal is made from high-quality material selected to resist temperature cycles and exposure to the refrigerant and lubricant mixture used in automotive air conditioning systems.
