Enginetech valve seats are precision-machined, hardened metal rings pressed or cast into a cylinder head to form the critical sealing surface for an engine's intake

Enginetech valve seats are precision-machined, hardened metal rings pressed or cast into a cylinder head to form the critical sealing surface for an engine's intake and exhaust valves. They maintain the airtightness of the combustion chamber and help transfer heat away from the hot valves. These valve seats are available in a variety of diameters, quantities, and finishes such as chrome nickel, powdered metal, and nickel-cobalt.

Additional details:

* Crafted from highly durable materials to withstand the extreme temperatures and repetitive impacts of high-stress environments
* Heat dissipation: They play a major role in engine cooling by drawing up to 75 percent of the heat from the exhaust valves and conducting it safely into the cylinder head
* Precision fitment: Enginetech designs their seats to exact factory specifications or oversized dimensions, making them highly popular for engine rebuilding, vehicle restoration, and performance applications
