E53 DISA valve seal not replaceable??

I have a vacuum leak coming from my DISA valve where it meets the intake manifold. I assumed I could just replace an O ring seal where it seats, but realoem/parts catalogs don't show the seal as replaceable. What is confusing to me is that if you check the parts listing for an E46 or E39 with an M54 engine, the DISA valve has a replaceable O ring with its own part number... To further confuse me, if I look at aftermarket DISA valve options, they show compatibility with E53, E46, and E39. What gives??? Can someone clarify this for me?
