Pyrroloquinoline Quinone is a relatively newer entrant in the world of nutritional supplements. Like CoQ10, PQQ possesses antioxidant properties but also offers unique benefits. Research indicates that PQQ can stimulate the production of new mitochondria, a process known as mitochondrial biogenesis. This is vital because mitochondria are the powerhouses of our cells, and increasing their number can lead to improved energy metabolism and enhanced cellular function.

- In addition to their durability, iridium spark plugs also provide a more reliable spark. This consistent spark helps to ensure that your engine runs smoothly and efficiently, reducing the risk of misfires and other performance issues. This can also lead to improved fuel efficiency, as a more reliable spark means your engine is burning fuel more effectively

- Crafted from high-quality oil-resistant materials, the 30x42x7 oil seal is impervious to the corrosive effects of petroleum products. The integrity of the seal is paramount; any compromise could lead to leaks that jeopardize the machine's lubrication and, consequently, its operational efficiency. Such a seal must maintain its flexibility and resilience under diverse conditions, from extreme temperatures to high-pressure environments, all while enduring the constant motion of rotating shafts.

What is Oil Seal
Availability
Oil seals go by many names, such as shaft seals, dirt seals, grease seals, lip seals, and many other variations of these. They are essentially simple devices used in rotary shaft equipment to prevent lubricant from escaping and for excluding contaminants such as dust, dirt and water. An oil seal’s most important function, however, is that it protects every type of ball, sleeve and roller bearing in the rotating shafts. The seals also prevent the integration of two different fluids that shouldn’t mix, such as oil and water.
Special seal types and their features
Fluid Types - Various oil seals are able to withstand interactions with oils, fuels, grease, water and more. Knowing what type of fluid the rotary shaft seal will be in constant contact with will ensure the longevity of the seal and surrounding components.
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.
