  • 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.

  • NGK Spark Plugs, often abbreviated as MGB Spark Plugs, are a renowned name in the automotive industry, especially when it comes to ignition systems. These plugs play a critical role in ensuring the smooth operation and optimal performance of engines, be it in cars, motorcycles, or even small engine-powered equipment.

  • When installing new spark plug wires, it is important to route them properly to avoid any interference with other engine components or excessive heat exposure. It is also essential to ensure the wires are securely connected to both the spark plugs and the distributor or ignition coil.
  • Oil seal installation

  • 1. Pressure: Many oil seals are used in high-pressure applications, so understanding the working pressure of your components is very important.

  • Proper installation of the 25x47x7 oil seal is essential to ensure its effectiveness. It is important to carefully clean and prepare the surfaces where the seal will be placed, as any dirt or debris can compromise the seal's ability to function properly. Additionally, the seal should be installed with the correct orientation and pressure to create a tight and secure seal.

  • Seals, including oil seals, have undergone a great development in recent years and are totally unlike the original product. PTFE has taken over the oil seals market for modern engines mainly because traditional oil seals started causing more and more problems. Such as evaporation of chemical plasticisers from the elastomeric material, which eventually caused engine oil leakage. Now, the focus is more on durability and frequency of servicing.

  • Valve cover gaskets and head gaskets play pivotal roles in maintaining the proper functioning of the engine. The valve cover gasket prevents oil leaks and contaminants from compromising the lubrication and performance of the engine, while the head gasket ensures the proper sealing of the combustion chamber, allowing for efficient fuel combustion and preventing the mixing of oil and coolant. Both gaskets are critical for the overall efficiency, performance, and reliability of the engine.
