Pyrroloquinoline Quinone (PQQ) is a relatively newer discovery compared to CoQ10. It is a redox cofactor that also functions as an antioxidant, playing a pivotal role in mitochondrial health. Mitochondria, known as the powerhouses of the cell, are responsible for producing energy. PQQ promotes the growth of new mitochondria, a process known as mitochondrial biogenesis, thereby improving energy metabolism and overall cellular function.

Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.
Regular maintenance and inspection of the oil seal are essential to ensure its continued effectiveness. Any signs of wear or damage should be addressed promptly to prevent oil leaks and potential damage to the machinery or equipment.

Meanwhile, rubber-cased oil seals are used under conditions where a metal-cased seal can fail (for example, because of thermal expansion). Unlike the metal-cased type, these seals do not rust. Moreover, they can seal a lightly damaged housing better than metal-covered seals since, in high temperatures, rubber can provide a more stable sealability.
