Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies. The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength. Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.

  • NBR, also known as nitrile rubber or nitrile, is the most popular material for an oil seal because of its good resistance to many oils and greases, such as mineral grease and hydraulic oil. Depending on their composition, synthetic oils and greases, such as those based on glycol, can damage NBR rubber materials. Depending on the amount of glycol, a PTFE lip seal may be the best choice. NBR is also unable to cope with contact with acids and solvents. The rubber is suitable for oil and grease at temperatures from -35 °C to 100 °C.

  • Oil Seals which are also known as rotary shaft seals are used to prevent lubricants from leaking and escaping. They protect key components of the machinery from being damaged from various fluids, dirt and dust from getting inside the machines. Oil Seals are a vital component in preventing harmful interactions between moving and static parts. Without using them you could cause expensive damage and halt whole operations. Using our 6 Guidelines for oil seals will help your buying decision. You can read about the different Oil Seals we stock  here.
  • Furthermore, the B20 series valve cover gasket helps to maintain compression within the cylinder head
  • b. Polyacrylate Rubber (PA) – also known as acrylic rubber, this material has better heat resistance than nitrile. PA is also recommended for a high surface speed environment. Operation temperatures are recommended from -4 to 302⁰ F (-20 to 150⁰ C). Polyacrylate rubber should not be used with water or in temperature below -4⁰ F (20⁰ C).

  • One of the key attributes of the BR7EF spark plug is its double-platinum design. This dual-electrode configuration not only extends the lifespan of the spark plug but also enhances its resistance to wear and tear, ensuring consistent performance over time. The fine wire center electrode reduces voltage requirement, allowing for a more stable spark and smoother engine idle.
  • However, rubber gaskets do have their limitations. They can be prone to (aging) and degradation when exposed to extreme temperatures, UV radiation, or certain chemicals. To address these issues, manufacturers often use additives or coatings to enhance the durability and performance of rubber gaskets.

  • Another benefit of neoprene foam gaskets is their versatility. These gaskets are available in a variety of shapes, sizes, and thicknesses to meet the specific requirements of different applications. Whether it's a simple O-ring seal or a complex custom gasket design, neoprene foam gaskets can be tailored to fit the unique needs of various industries.

  • Oil seals in any size, material or quantity

  • Glow plugs, the diesel equivalent of spark plugs, are designed specifically to aid in cold starts. In a diesel engine, air is compressed to a high temperature, which then ignites the fuel. However, when the engine is cold, this compression may not be enough to ignite the fuel. That's where glow plugs come into the picture. They generate heat before the engine starts, preheating the air in the combustion chamber, making it easier for the diesel fuel to ignite.
  • In terms of performance, the A7TJC spark plug excels in providing a cleaner burn, translating into better fuel efficiency and reduced emissions

  • This technique involves aligning the installation tool with the face of the shaft to precisely position the seal. Double-checking alignment after installation is essential to avoid future misalignment issues.

  • Valve cover gaskets are typically made from a variety of materials, including rubber, silicone, and fiber reinforced materials

  • In conclusion, LS1 spark plug wires play a crucial role in the performance and reliability of an LS1 engine. Choosing high-quality wires and ensuring proper installation and maintenance are essential for optimal engine performance. By investing in quality spark plug wires and taking care of them properly, LS1 owners can enjoy a smooth-running engine with maximum power and efficiency.
  • In the realm of automotive technology, the significance of spark plugs cannot be overstated. These tiny components play a crucial role in igniting the combustion process within an engine's cylinders, thereby propelling a vehicle forward. Among the various types of spark plugs available, platinum spark plugs stand out for their exceptional performance and durability.
  • The primary function of a head gasket is to prevent the mixing of coolant and oil with the combustion chamber's high-pressure gases. It also maintains the necessary compression ratio, which is crucial for the engine's ability to generate power. Without a head gasket, the engine would suffer from leaks, leading to a decrease in efficiency, overheating, and potentially catastrophic failure.
  • Beyond plumbing, the 1-inch rubber gasket finds utility in mechanical systems. In automotive parts like exhaust manifolds or engine cooling systems, these gaskets ensure that fluids or gases remain contained within specific areas, preventing performance-hindering leaks. Their resilience in high-heat conditions is particularly valuable, demonstrating the adaptability of simple rubber compounds.
