• No sealants required, simplifying installation and improving reliability
• Specifically engineered for Chrysler 6.1L Gen-3 Hemi engines with aluminum sleeved blocks

Construction & Design:

The Cometic MLS gasket is crafted from multiple embossed layers of high-grade stainless steel, providing exceptional strength and flexibility. The outer layers are coated with Viton, a high-performance fluoroelastomer rubber known for its excellent heat resistance and ability to maintain a tight seal under extreme conditions. This coating is applied on both sides of the gasket, enhancing its ability to conform to surface irregularities and resist chemical degradation.

The core shim layer is made from uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements. This multi-layer design not only improves sealing but also enables the gasket to rebound and maintain integrity despite thermal cycling and mechanical stress.
