CIP Film Keg Lube is a professional-grade, NSF-registered food-grade lubricant designed for use on draught equipment, valves, and gaskets. This 4 oz tube provides a high-viscosity barrier that prevents O-rings from drying and cracking, ensuring a 100% airtight and liquid-tight seal. It is specifically formulated to be resistant to CIP (Clean-In-Place) chemicals, meaning it won't wash away during routine alkaline or acid cleaning cycles. Essential for the maintenance of Cornelius kegs and commercial couplers.
