Another key benefit is the material's acoustic performance. Rigid mineral wool boards absorb sound, reducing noise pollution within and between rooms. This property is especially valuable in multi-family buildings, commercial spaces, and facilities where noise control is paramount.

- Another important factor is the quality of the oil used in the engine. Oils with low viscosity or poor quality can cause the main bearing oil seal to fail prematurely. Therefore, it is essential to use high-quality oils that are specifically formulated for use in engines. These oils have the right balance of viscosity and additives to ensure optimal performance and longevity of the oil seal.

When selecting a gasket for the valve cover, it is important to consider factors such as material quality, durability, and compatibility with the specific engine model. High-quality gasket valve covers are designed to withstand the demanding conditions of automotive operation, providing reliable sealing solutions that contribute to the overall performance and safety of the engine. Choosing reputable suppliers and manufacturers known for producing high-quality gasket valve covers is crucial to ensure the reliability and longevity of these critical components.

There is a British Standard laid down for the control of synthetic rubbers. BS 3574 (1989) helps to determine shelf life – for instance, Nitrile (NBR) and Polyacrylic (ACM) are Group ‘B’ rubbers and have a 7-year life, whilst Silicone (VMQ) and Fluoroelastomers (Viton®) are Group ‘C’ rubbers and have a 10-year shelf life. PTFE and Leather do not come into this category but like the others should be kept in the original packing for as long as possible away from direct light, dust, and humidity. Ozone, which can also be produced by battery-driven forklift trucks has a very bad effect on synthetic rubbers. Finally, protect the sealing lip – DO NOT hang the seals on nails, wire etc.
