Penrite Radiator Stop Leak 375ml

Radiator Stop Leak is a high-quality, water-based sealant designed for temporary sealing of the cooling system. It quickly and effectively seals the radiator, heater core, head gasket, hose connections, and plugs in automotive engines, protecting against severe damage caused by coolant loss and overheating.

Application

Radiator Stop Leak is suitable for all motorcycles, passenger cars, 4WD vehicles, light and heavy commercial vehicles, construction, mining, agricultural machinery, and stationary engines. It is compatible with all materials including aluminum, cast iron, copper, brass, plastic, and rubber hoses. One 375ml bottle is sufficient for 6-12 liters.
