Kibblewhite Precision Machining

High chrome valve seats

Californian valvetrain specialist Kibblewhite Precision Machining has added a newly engineered line of high chrome (HC) valve seats, which have 18-22 percent chromium content for increased resistance to abrasion, corrosion and deformation. 

Additionally, a 1-2 percent nickel content adds toughness and further corrosion resistance. They can be easily machined and form a continuous chip, which is quite different to what can be expected from powder metal.  All HC seats are ground to exacting tolerances and designed to be used in universal applications.
Founded in 1939 by present CEO Will Kibblewhite’s father, the Pacifica, California based business is noted for the exacting tolerances of its precision machining techniques and investment in advanced materials research and emerging technologies.
Employing some 26 people and operating from 20,000 sq ft of machine shop, offices, engineering departments and warehouse space, KPMI is noted for the custom valvetrain solutions it offers and use of their products in some of the most demanding motorsport race conditions.
