Which orings do you need? Pyramid air has the tech manual but I have not found it online. Gotta call them or tell us which ones you need, I have purchased several different sizes and may be able to help you.
I looked for hours trying to find one , only found a sky. of the parts on kral site they have no list of o-ring sizes. Go to P.A order a complete rebuild kit for around $ 20.00 (O-rings only) do not forget to order the valve stem also . Good luck darell
