These injector seals have been tested in engines producing well over 1000 hp. They're made from beryllium copper treated with a proprietary process. Overspeed was the first to release this style of injector seal, which utilizes two crush points. Extensive dynamic simulations were used to finalize this innovative geometry. Proudly MADE IN USA with precision machining that yields tightest fit with finest surface finish for the best seal possible.
