Analyzing MLX vs. MLS Gaskets by Cometic

Saturday, May 20th, 2023

Gaskets are vital components in automotive engines, serving as seals between different parts to prevent fluid and gas leaks. This article will highlight the reasons why one should be concerned about the condition of gaskets in their vehicle. Additionally, we will explore the distinctions between MLX and MLS gaskets, shedding light on their unique features and applications.

Importance of Vehicle Gaskets (approx. 180 words): Gaskets play a crucial role in maintaining the overall performance and reliability of a vehicle. They are used in various engine systems, including the cylinder head, intake manifold, exhaust manifold, and water pump. The primary reasons for being concerned about gaskets are as follows:

  • Leakage prevention: Gaskets ensure a tight seal between engine components, preventing the escape of fluids such as oil, coolant, and combustion gases. Leaks can lead to engine inefficiency, overheating, and even catastrophic failures.

  • Compression and sealing: In the cylinder head, gaskets seal the combustion chamber, allowing optimal compression and preventing leakage of gases between cylinders. This contributes to engine power, efficiency, and emission control.

  • Heat resistance: Gaskets are exposed to extreme temperatures generated by the engine. They must possess the ability to withstand these conditions without deforming or losing their sealing properties.

  • Longevity and maintenance: Regular inspection and replacement of gaskets can help identify potential issues early on, preventing costly repairs and minimizing vehicle downtime.

Comparative Analysis of MLX and MLS Gaskets by Cometic Cometic, a renowned gasket manufacturer, offers two popular options: MLX and MLS gaskets. While both types serve similar purposes, there are notable differences between them.

MLX Gaskets: Active combustion seal embossments are located on the outer layers of the gasket. The center layer “stopper” seal is a fold-over design that is typically .006” thick. This layer limits full compression (yielding) of the combustion seal embossments while increasing stress in a small (.060” wide) cross-section around the combustion chamber. No sealants or re-torquing is required.

MLS Gaskets: Active combustion seal embossments are located on at least two of the gasket layers (gasket shown has three active combustion seal embossments). Creates an exceptional seal by requiring less clamp load, resulting in less bore distortion. Water/oil seals are located on the outer layers. Shim layers may be included to increase overall gasket thickness. No sealants or re-torquing is required.

In the end, being concerned about the condition of gaskets in your vehicle is essential for ensuring engine performance, reliability, and longevity. Cometic's MLX and MLS gaskets offer distinct advantages based on specific engine requirements and conditions.
