Coats to Seal Leaks

Unlike other cooling system stop leak products, Ceramic Motor Seal is a professional treatment process that literally forms a thin and extrememly durable coating over all the surfaces in the engine cooling system. Not only sealing gasket leaks, but also metal porousness and small cracks.

Durable Leak Solution

Properly applied to your engine cooling system the resulting coat is "rock-hard" and will withstand even the most grueling temperatures. It's "glass-smooth" surface promotes better coolant flow which also improves cooling performance.

A Low Cost Repair

The cost of applying Ceramic Motor Seal is far less than the cost of opening or re-opening an engine that is leaking, or even just weeping coolant from a micro fracture or a porous spot in the casting. It can even stop leaks that may occur from bearing or sleeve replacements. Do yourself a favor and get a bottle now.

Who We Are

We are The Professionals Choice

Irontite was born in 1952 to offer to the engine rebuilding industry (machine shops) a Crack Detection and Repair set of products. Our professional detection and cold repair process was widely received. Early in the 1950's the need for a coolant sealant grew out of professional machine shops that repaired castings, cylinder heads and blocks. The machinist required a method to seal off casting imperfections. Irontite developed Ceramic Motor Seal to fill that need.
