A comparable choice if you are looking for a K-Seal style coolant leak sealer. B-RAL is an independent brand and is not made by, or affiliated with, K-Seal.

Key Benefits

• No flushing: simply pour and go

• Carbon fibre for added strength

• Radiator stop leak: designed for small coolant leaks

• Also for water pumps, heater cores and freeze plugs

How It Works

Coolant leak sealers circulate around the cooling system with the coolant. When they reach the point where coolant is escaping, they are designed to help seal small leaks. The carbon fibre content is included to add strength to the seal. Results depend on the size and location of the leak.
