I NEED TO REPLACE A Clamp Ring Nut for my Sta-Rite 135 TX Cartridge filter. The Nut i was recomended does not fit 35-612-1-25. I try the part yesterday and it won't fit the original bolt already in the clamp. It is to small and i did not want to damage the tread. Is there any other nut that you recommend for this clamp?
