Since its early beginning as a manufacturer of core hole plugs for cylinder block castings, Pittsburgh Plug & Products Corporation has specialized in contract manufacturing for the automotive industry.
Today, our products are forged on National Cold Formers, using five dies to produce a variety of sizes, lengths, and head styles. Coiled wire is the principal raw material ingredient with sizes ranging up to over 1-1/16 inches in diameter. Essentially a scrapless operation, with no cut-off or trimming waste, all plug blanks are held to extremely close tolerances to assure leak-proof seals after threading. Secondary operations performed on special purpose automatic machines, suitable for chucking, machining, and roll threading, compliment fast and efficient production methods.
