  • When selecting a natural rubber gasket for your specific application, there are several key factors to consider. The first is the hardness of the gasket, which is typically measured on the Shore A scale. A softer gasket (lower Shore A hardness) is more flexible and better suited for applications where the sealing surface is uneven, while a harder gasket (higher Shore A hardness) provides better resistance to compression and extrusion.


  • Low or high temperatures
  • The quality of the rubber or rubber fabric used to make an outer case is the same as the quality of the rubber sealing lip. Fabric reinforced rubber is, as the name suggests, rubber reinforced with a fabric.

  • This article provides an overview of Iridium Spark Plug, a revolutionary new product that is set to redefine the spark plug industry with its advanced technology and performance. By focusing on the benefits of iridium and the unique design of the spark plug, the article highlights the many advantages that Iridium Spark Plug offers, making it a must-have for modern engines.
  • The humble engine spark plug, a seemingly minor component within the complex machinery of an automobile, plays a pivotal role in ensuring smooth and efficient vehicle operation. These unsung heroes of the automotive world are responsible for igniting the air-fuel mixture in the combustion chamber, a process fundamental to powering internal combustion engines.
  • The Significance of Rear Shock Absorber Oil Seal Maintenance
  • Oil seals, often made from high-quality rubber compounds or synthetic materials, are designed to prevent the leakage of lubricants while inhibiting the ingress of contaminants. The 8 in the name likely refers to the percentage of oil-resistant material used in the seal's construction, enhancing its ability to withstand exposure to various oils and lubricants without degradation.
  • Special shape code
  • Cover jagged edges: Sharp and jagged corners can cause tears in the o-ring. They have to be covered as even a tiny tear can break the seal.

  • Ultimately, the best type of spark plug for your vehicle will depend on your specific needs and budget. It's important to consult with a professional mechanic or automotive expert to determine the right spark plug for your engine. By selecting the right spark plug, you can ensure optimal engine performance, fuel efficiency, and reliability.
  • The front hub oil seal is an essential component of any vehicle's wheel assembly. Its primary function is to prevent the lubricant from leaking out and contaminants from entering the hub, which could potentially damage the bearings and other internal components.
  • A rubber edge gasket, seemingly an unassuming component, plays a crucial role in various industries ranging from automotive to plumbing, and from aerospace to food processing. This simple yet effective sealing solution is the silent hero that ensures the integrity and functionality of numerous systems.
  • Oil seals, also known as oil lip seals, dirt seals, grease seals, shaft seals, or rotary seals, are used to fill the gaps between stationary and revolving parts of the equipment. They are designed to prevent the leakage of fluids from the machinery and inhibit contaminants from reaching these fluids. They contribute to the longevity and reliability of the equipment like engines and gearboxes in industrial equipment. This post discusses the importance of oil seals, the different types of materials that are used in the manufacturing of oil seals and many more.

  • Pressure: As the pressure increases, the radial load and the friction of the sealing lip increase in contact with the shaft. As with temperature, each oil seal has a recommended pressure for optimum performance. Excessive pressure causes the seals to wear more quickly and consequently have a shorter life.
  • T-shaped gaskets, a specialized category within the vast domain of sealing solutions, play a pivotal role in numerous industrial applications. Their unique design and functionality make them indispensable components in ensuring leak-proof connections and maintaining system integrity.
