Straight Carbide Valve Guide Pilots - .375 Top

Our carbide valve guide pilots are manufactured from fine grain sintered tungsten carbide and are ground to a very high degree of accuracy, straightness and surface finish. Only solid carbide pilots can provide the accuracy and rigidity for highly accurate valve seat machining. This is especially critical for high performance engines and very small valve guides. The high strength and wear characteristics of solid carbide helps minimize deflection, ensuring valve seat to valve guide concentricity.
