The Victor Reinz Reinzosil RTV Silicone from Dana Incorporated is a permanently elastic and universal silicone sealing compound that provides resistance to fluids and extreme temperatures. Reinzosil is an easy-to-apply, fast-curing, and durable sealant that is thermally stable in extreme temperatures and suitable for uneven and rough surfaces. It's also resistant to fluids, including mineral oils and synthetic oils, lubricants, gasoline, diesel oil, greases, water and detergents, and is safe for all sensors. The silicone is ideal for use on two-dimensional flat surfaces where there is a sealing gap, such as gasket intersections and components originally sealed with room-temperature vulcanizing (RTV) by the manufacturer, including intake manifolds, valve covers, and oil pans.
