Safe-seal Function

Intelligent material O-ring expands automatically up to 10% - 20% when exposed to engine oil. This seals the oil pan from inside the thread rather than just from the outside. 


SMART-O® plugs provide powerful, safe sealing beyond any other oil drain plug system in the market.


The use of SMART-O® plug prevents oil leaks and ultimately engine damage.
