Not all that expensive, considering how little you need to use.Also, I've seen three or four videos now on how to change the spool for an SPG, and they all mention using "oxygen safe" grease. So I keep wondering if I need to hunt down Viton o-rings and buy the ridiculously expensive O2 safe grease just to put in a new air spool. (Both my Scubapro and Subgear SPGs don't work with the shouldered spool I have - they won't swivel).
