The original samples that we signed off on for production had the correct liners, as did the first shipment of hoses that we tested and ran for over a year before releasing them to market. Somehow on the 2nd batch of hoses we received the correct material was not used, this is not something that we were able to detect and some hoses have shown signs of sweating. We are in the process of restocking with the correct material lines and have offered to replace any Z1 Silicone Hoses that are showing signs of oil sweat.
