CoQ10 is a naturally occurring antioxidant found in every cell of the human body, playing a crucial role in the production of adenosine triphosphate (ATP), the energy currency of cells. As we age, the levels of CoQ10 in our bodies tend to decline, which can affect our energy production and overall cellular function. Supplementing with CoQ10 is known to support heart health, improve energy levels, and enhance physical performance. Additionally, emerging research suggests that CoQ10 may play a role in reducing oxidative stress, benefiting conditions such as hypertension, neurodegenerative diseases, and chronic fatigue syndrome.

Despite its advantages, chlorination does present some challenges and concerns. The reaction of chlorine with organic matter in water can produce by-products known as trihalomethanes (THMs) and haloacetic acids (HAAs), which are classified as potential carcinogens. To mitigate these risks, water treatment plants often conduct regular monitoring of chlorine by-products to ensure they remain within acceptable limits set by health authorities.

The range of uses of peroxydically cross-linked EPDM includes in hot water and steam seals. EPDM is also very resistant to ageing and ozone. Compared with the usual types of synthesis natural rubber it has good resistance to cold temperatures. EPDM is not resistant to aliphatic or aromatic hydrocarbons or mineral oil products. Resistance to chemicals, and also to oxidising agents, is very good. Temperature range from -50 °C to +140 °C depending on type.

The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
- fluorosilicone rubber is more and more commonly used in the manufacture of seals.
- The e6tc designation refers to a specific type of spark plug that is engineered for use in a variety of internal combustion engines. These plugs are characterized by their exceptional heat range, which makes them suitable for high-performance applications. The e6 part typically denotes a specific heat range rating, indicating how well the plug can dissipate heat from the firing end to the engine's cylinder head. The tc often represents the plug's thread size and reach, ensuring a precise fit within the engine's combustion chamber.

Modern engine oils, such as the current SG classification for gasoline engines, contain a large fraction of additives, many of which are detrimental to fluoroelastomers. The primary functions of oil-additive packages are to protect metal parts, avoid deposits in the engine, minimize oil degradation, and adjust fluid viscosity. Little attention has been paid to avoiding damage to rubber seals. Instead, elastomer producers have been expected to provide new, higher-performing products at no increased cost to auto manufacturers. Among the additives with moieties that may attack fluoroelastomers at high temperature are detergents (phenolates), dispersants (succinimides, alkylphenol amines), and antioxidants (amines, sulfides, hindered phenols).4 Many of these components are multifunctional, containing phenol or amine groups that can dehydrofluorinate and crosslink VDF-containing fluoroelastomers, leading to loss of elongation and eventual embrittlement. However, the rate and extent of reactions with seals are affected by many factors, including whether air is present in the system. When oil is exposed to air at high temperature, additives may undergo considerable changes. For example, a significant fraction of amines may be oxidized to amides, which have little effect on fluoroelastomers.5
What are Oil Seals – A guide to Oil and Rotary Shaft Seals
The metal case is the exterior (or frame) of the oil seal, the principal function of which is to give rigidity and strength to the seal. The material of the case must be selected depending on the environment where the seals are to be used. Often the metal case is covered by the same rubber material used in the sealing element, which also helps seal the exterior of the oil seal in the housing bore. Common case material types are:
