My bad. The QR has open close on it also, but looking closer the seals do indeed say open and this is to remove the seal. The 35mm dia. hubs are 7800 series, not these.
Uniglide and Hyperglide have the same ID. The only differences are the teeth and how it is affixed to to the hub. HG use a lock ring and UG uses a threaded cog. The hub you have is compatible with both. I know this because I have two sets of this exact hub.
