I bought two of these filters and I am completely satisfied with the product. Brass and copper fittings and connections were used, with PVC ball valves at the inlet and outlet of the filters there were no leaks. Some of the brass and plastic threads seemed a bit loose so I used both pipe protection tape and pipe thread sealant on all the fittings and it worked great. I installed the filters, just turned the case manually, there is no leak. The o-ring on these cases is thicker than the o-rings I've used in the past so they seal well. Very happy with both filters
