Aquadyne O rings size or replacement kit

[BFin]

I purchased an Aquadyne 1.1 filtration system in 2006 and it still functions well. The control head has gotten quite stiff, and I would like to lubricate it per the instructions that came with it. I am fearful that in dismantling the head after so many years, that I might damage the o rings, so I would like to have on hand some spares (the true way to keep damage from happening!). I have tried contacting Aquadyne by phone and email and have had no response--I fear the worst for the owner(s). I would appreciate it if anyone knows the sizes of the various o rings and/or a supplier for Aquadyne replacement parts. Thanks, and Stay Safe.

Take the o ring with you and go to one of the big box stores or an automotive store, one of those places will sell o rings, can even by a case of various sizes
