Hi I have the erecaid manual ved pump. I read a hawk post saying to use flat washer like rings. Im looking at the timm webpage. They have ez ring tension rings. Problem is there 27 bucks. I was using two standard rings B and C together. How would I go about finding the best tension for flat washer without blowing thru money?
I mention flat washer-like rings only in use of a Vacurect which is a VED with a different design. It is made for use with the flat rings. I think it is a clearly superior system for ED.
I doubt you can use such rings with most other VED's. Why are you interested in changing from the standard bands?
