A heavy duty sanitary lubricant with extended performance, low friction properties. This lubricant is designed for longer lubrication intervals, eliminating downtime to re-lubricating o-rings and seals. It also helps prevent leaks from your kegging equipment. Keg couplers and party pumps last longer and work better with regular application of a sanitary, non-toxic lube and because you're serving beer, it has to be food grade. Lubricants like this one are specially made to meet all USDA guidelines.
