Pursuant to the "lesson learned" thread, I'm in need of the small o-rings for the valves on a later (turbo) style 617 vacuum pump. They're apparently very weird proprietary pieces and hydraulics/hose fittings-type places can't get anything equivalent to them (something about the section width being less than the thickness), so used original ones are in order.

If anyone has an old broken "parts" pump laying around, please send me a PM.

Thanks,
Tom
