Spray'n'Seal Leak Repair is a sprayable sealer that forms a durable rubber barrier that stops leaks in minutes. The wicking action seals hard-to-reach leaks without the need for disassembling or removing parts. Designed specifically to target low pressure leaks in hoses, oil pans, differentials, transmission pans, as well as plastic, PVC and metal pipes, their connections, and much more. Eliminates the need for liquid additive sealers that can swell and foul internal seals. Resists common shop fluids. Packaged with extra spray nozzle and straw attachment. Suggested applications: Engine and transmission leaks, hoses, oil pans, differentials, transmission pans, cooling systems, thermostats, water pumps, valve covers, tubing connections, electrical harness connectors, plastics, PVC and metal pipes.
