Original BMW HVAC Gasket O-Ring for E60 5 Series, E63 and E64 6 Series, M5, and M6 (2004–2010)

Part 64-11-6-933-923 is an Original BMW gasket, sold as an O-ring, that seals a joint in the heating and air conditioning system of the E60 and E61 5 Series and the E63 and E64 6 Series, M5 and M6 included. BMW names it simply "gasket," and it weighs just 1 gram. Production of this number began in June 2003, and it remains the current part. It is made in Germany and sold by the piece. An O-ring sits in a groove between two mating parts and compresses when they are joined, keeping fluid or air inside its passage.

Original BMW Parts carry a 24-month parts warranty.

The same gasket appears across the full E60 and E63 era, both before and after the facelift. BMW's parts data shows it on the M54 and N52 six-cylinders, the N52N, N53, and N54 that followed, the N62 and N62N V8s, and the S85 V10 in the M5 and M6, along with diesels sold outside the US. Because the part does not change by engine, an E60 545i and a later 535i take the same number. It also covers the E61 Touring, the E63 coupe, and the E64 convertible, so body style does not change the part either.
