Construction & Design
The Cometic MLS gasket features a sophisticated multi-layer steel design, combining three to five layers of high-grade stainless steel. This layered construction provides exceptional strength and flexibility, allowing the gasket to rebound after compression and maintain a tight, leak-free seal. Embossed outer layers conform to surface irregularities on the cylinder head and engine block, enhancing sealing performance.
Both sides of the gasket are coated with Viton rubber, a synthetic fluoropolymer known for its outstanding heat resistance and chemical stability. This coating protects the gasket from corrosion and degradation caused by exposure to engine fluids and extreme temperatures, ensuring long-lasting durability and consistent performance.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
