Why prefer Silicone?
Silicone had established as state-of-the-art material in automotive engineering, pioneering technologies and high – performance components in rubber industries.
LT High Performance has taken great care to manufacture its range of valve cover gasket to the exact same specifications and quality standards as the original OE items.

The Benefits of Silicone
- Feature high heat resistance
(Normal silicone is 230°c BUT our developed silicone can provided up to 270°c) - Prevent Corona effects
- Dielectric Strength
- Reliable protection against water splash, damp and dirt
- Good electrical insulators
- Low Toxicity

Combating Shrinkage
Silicone, NBR and EPDM have their different combating shrinkage after store in room temperature.
BUT, our tooling molds for valve cover gasket are specially developed for silicone material to perfectly fit into the valve cover gasket to avoid any leaking/ faulty.
