Maintaining the right pH level is essential for the effective operation of cooling towers. A pH value that is too low or too high can lead to increased corrosion or scaling. pH control chemicals, such as sodium hydroxide or sulfuric acid, are used to adjust and stabilize the pH, ensuring it remains within the optimal range. Regular monitoring of pH levels is crucial, and automated dosing systems are often implemented to maintain pH balance efficiently.
In recent years, the importance of stability testing has also extended to biopharmaceuticals. As these products, which include biologics derived from living organisms, often involve complex molecular structures, traditional stability testing approaches must be adapted to accommodate their unique characteristics.
When considering adding CoQ10 and PQQ to your supplement regimen, it’s essential to choose high-quality products from reputable manufacturers. They are available in various forms, including capsules, softgels, and powders, so it’s crucial to select an option that fits your lifestyle and preferences.

- Spark is the life force that these plugs channel into the engine. When an ignition system sends an electrical current to the spark plug, it jumps the gap between the center and side electrodes, creating a spark that ignites the compressed fuel mixture in the combustion chamber. This spark is the catalyst that transforms potential energy into kinetic energy, propelling vehicles forward. The efficiency and reliability of this process are critical to engine performance and depend largely on the quality of the spark plug.
Standard 3760/3761
Reinforced GVP design for larger diameters, with rotation speeds of up to 15 m/s and pressure of 3-4 bar
Polyacrylate Oil Seals - Mostly selected for automotive and transmission uses, polyacrylate seals are able to withstand fuel, oil, ozone, sunlight and weather when used. With cars exposed to all these different fluids and elements, they are the perfect choice. However, they should not be used in low temperatures, as their flexibility weakens when cold.
In automotive applications, the proper functioning of oil seals is crucial for maintaining the performance and longevity of critical components. Trailer hub oil seals and Tora oil seals, among others, are essential for preventing oil leakage, minimizing friction, and protecting internal components from wear and damage. High-quality oil seals contribute to the overall efficiency, safety, and reliability of vehicles and machinery.
Pour-point depressants: This additive has nothing to do the actual pouring of your oil. In fact, pour-point depressants help prevent the wax particles in the oil from hardening in cold conditions. As a result, the motor oil flows freely even in low, cold temperatures and the engine doesn’t need to work any harder to pump it.
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.
Overall, the 40mm rubber gasket is a versatile and reliable sealing solution that is widely used in various industries for different applications. Its ability to provide a tight seal, resist high temperatures and pressure, and dampen vibrations makes it a valuable component in ensuring the efficiency and reliability of industrial equipment and machinery. Whether in plumbing systems, automotive engines, or hydraulic systems, the 40mm rubber gasket plays a crucial role in maintaining operational efficiency and preventing costly leaks or contamination.
Seals are classified by O.D. wall material, lip type, and whether they have a spring or not.
Major oil seals are specified in ISO 6194-1 and JIS B 2402-1.
Table 2 shows the common types of oil seals, while Table 3 shows the features of each type of oil seal.
Table 4 lists the JTEKT oil seal type codes and corresponding ISO and JIS standards.

Oil seals are available in an immense range of sizes, for shafts from a few millimetres to several metres. Once the shaft diameter, groove diameter (housing diameter) and groove width are known, selecting an appropriate oil seal is a simple task. An oil seal or its product description is usually associated with three dimensions, for example 6x15x4. These refer to the sizes of the hardware for which the oil seal is designed. In this example, this oil seal is suitable for: 6-mm shaft diameter x 15-mm groove diameter x 4-mm minimum groove width.
