High Temp Valve Stem seals


These seals are designed as a direct replacement for the OE part but with performance in mind. The OE type seals are recommended for standard OE diameter valve stems only. We use only OE type materials for these seals including Viton©, polyacrylate and nylon. While many competitors use low quality nitrile materials we use only OE material or better. We've got you covered with a full line of seals for your rebuilding requirements.
