In 2019, EFSA published a statement on the review of the risk related to the exposure to food additive titanium dioxide (E171) performed by the French Agency for Food, Environment and Occupational Health Safety (ANSES). In its statement, EFSA highlighted that the ANSES opinion reiterated the uncertainties and data gaps previously identified by EFSA and did not present findings that invalidated the Authority’s previous conclusions on the safety of titanium dioxide.

Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

  • Oil leaks are more than just a mess; they signal a loss of the lubricant crucial for your engine's health. As the oil level drops, engine components run the risk of overheating or even seizing up, leading to costly repairs or, in severe cases, engine failure. Moreover, the introduction of dirt and debris through a compromised gasket can cause wear on the camshaft and valve train, reducing the engine’s efficiency and longevity.
  • In conclusion, the National Skeleton TC Oil Seal is a versatile and reliable solution for preventing oil leaks in a wide range of industrial applications. Its design, materials, and performance make it an essential component in maintaining the smooth operation of machinery and avoiding costly maintenance issues. Businesses that prioritize the quality and performance of their machinery would do well to consider the benefits of using the National Skeleton TC Oil Seal in their operations.
  • In addition to preventing oil leaks, the C15 valve cover gasket also plays a role in maintaining the engine's performance. A faulty gasket can cause a loss of compression, which can reduce the engine's power and efficiency. This is because the gasket helps to create a tight seal between the valve cover and the engine block, which is essential for maintaining the correct pressure within the engine.

  • Recognizing and avoiding common installation mistakes is key to the longevity and effectiveness of oil seals. Here are some frequent errors to watch for:

  • In this blog, we attempt to highlight what are Oil Seals and the various Rotary Shaft Seals including Mechanical Face Seals, Water Pump Seals, Gland Packings, and V-Seals that are readily available.

  • The quality and condition of spark plug wires significantly impact the performance of an engine. Worn or damaged wires can lead to misfires, reduced power output, and decreased fuel efficiency. Regular inspection and timely replacement of spark plug wires are essential for maintaining optimal engine health. A well-functioning set of wires ensures smooth idling, improved acceleration, and a more consistent overall driving experience.
  • In recent years, advancements in spark plug technology have brought about significant improvements. Platinum, iridium, and even diamond-coated spark plugs have been developed, offering longer lifespan, better fuel economy, and increased durability. These premium spark plugs are designed to withstand higher temperatures and pressures, making them ideal for modern high-performance engines.
  • O.D. (outside diameter) surface

  • Unscrew the pulley bolt anticlockwise with a socket and bar. Start it turning with a sharp blow on the bar.

  • Auto oil seals are integral to the functionality of various automotive components, including the engine, transmission, and wheel assemblies. These seals are designed to contain lubricating oil and prevent leaks, contributing to the efficient operation and longevity of the vehicle. Proper maintenance and replacement of auto oil seals are essential to ensure the reliability and performance of the vehicle's systems.

  • The pulley is kept from turning on the crankshaft by a key fitting into grooves on the crankshaft and pulley.

  • The selection of the right high pressure oil seal is critical

  • You may need to turn the crankshaft so that it protrudes less. Turn the front pulley bolt with a spanner or socket.

  • In conclusion, the wheel hub oil seal is a vital but often overlooked component in automotive engineering. Its role in maintaining the health and safety of a vehicle is immense. As technology advances, so do the materials and designs of these seals, offering better resistance to wear, higher temperature tolerance, and improved sealing efficiency. Therefore, understanding and appreciating the importance of this small but mighty part is crucial for both vehicle owners and mechanics alike. Remember, prevention is always better than cure, especially when it comes to the intricate mechanisms that keep our vehicles running smoothly.

  • Heat resistance

  • The major cause of extrusion and nibbling is stress caused by high pressure. This is commonly noticed when the oil seal has a chipped or nibbled look. In fact, in some cases, the surface of the seal tends to peel on its own, which makes it have a shaved look. What the stress does is that it increases the clearance gap between the mating edges, which causes the seal to get entrapped, and then leads to severe physical damage.

  • High Mileage Motor Oil

  • In conclusion, wheel oil seals are a critical component of a vehicle's wheel assembly, serving to protect the wheel bearings from contamination and maintain proper lubrication. Regular inspection and maintenance of wheel oil seals are essential to prevent damage to the wheel assembly and ensure the safety and performance of the vehicle. By understanding the importance of wheel oil seals and taking proper care of them, drivers can enjoy a smooth and trouble-free driving experience.

  • First, an elastomer, most often nitrile, is vulcanised to a metal ring. This creates a stiffening effect that includes a specialised metal tension spring directly behind the sealing lip, keeping the oil seal firmly in place against the moving part.
