Genuine DuPont Viton fluoroelastomer is used in GSC Power-Division Viton Valve Stem Seals. Viton was created especially for the harsh environments present in modern high-horsepower turbo engines. GSC Power-Division Viton valve seals are held to a higher standard and offer extended wear, as observed in high rpm or high mileage engines, as well as better resistance to high temperatures, fuel, and chemical pollutants. Since GSC Power Division doesn’t believe in taking shortcuts, both the intake and exhaust valve seals are replaced using Viton valve seal kits. GSC’s Viton valve seals offer all of this performance at a fraction of the cost of OEM dealership parts, making them ideal in any circumstance.

Note: Sold as a set of 12 Intake 5mm stem seals.
