- KPMI® solid Viton® valve stem seals are designed to have optimum fitment, allow for maximum lift, and to give maximum life
- KPMI® Red valve stem seals are resistant to high temperatures, petroleum products and the corrosive gasses that are the by-products of combustion
- These seals retain their ability to seal in situations where other materials could harden and allow oil to enter the combustion chamber causing detonation, carbon build up and a loss of power
