I have always used Earl's or Russell fittings but they are so damn expensive. I am designing and pricing plumbing for my remote mount pump/reverse cooling setup and it is looking like over $700 just for hose/fittings. I was wondering about Fragola or even some of the other brands that I see listed on Ebay. There are even a few Chinese manufacturers selling fittings at fractions of the price of the big name brands but I was concerned about the quality. If I buy the cheapos and have to replace with the better ones anyway it ends up costing money.
