Review on EVIL ENERGY 6AN 90° Push Lock Hose Fitting Black (End) by Ronnie Staver

It wasn't a good photo to see but at the 90 outside bend the material shrank and deformed (possibly microcracks) from the bend. You won't see this in a quality product like Earl's Hardware. But the same faucet at Earl's is about three times as big. I only use it for vapor so no pressure is applied. I wouldn't put pressure on these fittings. But for the price I would buy it again for use in steam applications like crankcase ventilation.
