So i went to Lowes tonight to buy these supplies you used and lets just say i walked out empty handed... LOL. i could not figure it out for the life of me... finding the correct gasket stopped me from buying the stuff, so i walked and i think the guys knew what was up when i needed help. They asked me what i was building and i told them it was a home water filtration system. LOL. It seemed to fit the description but they gave me a weird look. I need to change my setup and i think i'll stick with the tubing, unless you have specific part numbers on hand..
