We are the nation's largest after market valve seat company in the world; manufacturing valves seats to order, quickly and with extreme quality control.  Tucker Valve Seats are used by Original Engine Manufacturers and some of the World's Largest Rebuilders of Automotive and Industrial Engines. Tucker Valve Seat Company is the only full line valve seat insert manufacturer in the United States.

What makes Tucker Valve Seats different?  Tungsten, alloyed with Chrome, Molybdenum and Vanadium in a tool steel base, creates an extremely strong alloy. This gives Tucker valve seats a greater wear resistance and better ability to withstand higher heat than competitor's seats.

The patented Tucker valve seats can safely operate in excess of 1400° F temperatures. The competition typically loses its hot hardness at or about 1100° F.

Each Tucker Valve Seat is individually cast using a process that, together with the special alloy, gives greater resistance to oxidation from fuel contaminates, such as sulphur. Unlike other seats, Tucker tungsten seats will not cause valve and valve seat "pocketing" and recession.  more >>
