I am converting my coleman 5 gallon beverage cooler into an MLT, and im not sure about some of the equipment im using that will be going inside the cooler.
To create some good seals between the stainless steel washer and the inside wall of the cooler and the s.s. washer and the barb, im using a couple of rubber washers. One is a black rubber faucet washer and the other is a red garden hose washer. The packaging for both did not say anything about heat resistance. Does anybody know if these will withstand mashing temperatures, and if there are any health risks?
