  • Allowable internal pressure
  • Its ubiquity notwithstanding, the small rubber gasket's significance is often overlooked until a failure occurs
  • Furthermore, the A7TJC spark plug's design incorporates a resistor, which helps suppress radio frequency interference, ensuring a smoother engine operation and preventing potential electronic system malfunctions. This feature is particularly beneficial in modern vehicles with advanced electronic control systems.

  • Leather Oil Seals - Leather Seals, also known as Type L Oil Seals, are most common in components that are subject to dirt and poor lubrication. Since they come pre-lubricated and are able to absorb fluids, leather oil seals are able to provide sealing properties in conditions that synthetic rubber is unable to.

  • The Revolutionary Impact of Spark Plugs on Modern Vehicles
  • 1. Cost High temperature rubber gaskets are generally more expensive than other types of gaskets, which may limit their use in some applications.

  • • Machining of lip surface (stable oil drip under pressure)

  • The cost of new spark plugs can range from as low as $2 to as high as $20 per plug. Cheaper spark plugs are often made of basic materials and may not last as long as more expensive options. On the other hand, high-quality spark plugs are made of premium materials such as platinum or iridium, which can resist wear and corrosion better than cheaper materials.


  • Heat resistance

  • Spark plugs, typically costing between $5 to $20 each, depending on the type and quality, are designed to withstand high voltage and extreme temperatures. Premium iridium or platinum spark plugs can be more expensive but offer improved durability and performance. A standard four-cylinder engine requires four spark plugs, while a six or eight-cylinder engine will need more, thereby affecting the overall cost.
  • Spring-Seal

  • Oil seals with outer metal cases may include finishes or treatments applied to the outer edge to aid in rust protection, identification, and sealing of scratches or imperfections in the housing bore. Common finishes applied to the outside edge of metal O.D. oil seals include plain (a bonding agent of usually a yellowish-green color), a color-painted edge, and a grinded-polished edge.

  • Spark plugs are essential components in the internal combustion engines of automobiles, providing the necessary spark to ignite the air-fuel mixture and power the vehicle. The Spark Plug 794 055A is a high-performance plug designed for use in various applications, including passenger cars, light trucks, and motorcycles. In this article, we will provide a comprehensive guide to help you understand the features, benefits, and proper installation of the Spark Plug 794 055A.

  • Nitrile is the most widely used rubber (elastomer) and it’s recommended as the best for almost all standard applications. This is solely due to the fact that nitrile has some intrinsic properties, such as low cost and compatibility with most environments. Some of the general applications of nitrile are non-latex gloves, automotive transmission belts, footwear, gaskets, synthetic leather, hoses, o-rings, and oil seals.

  • Oil seals are used in any industrial application that has a rotating or moving part assembly. This includes:

  • Variety of Oil Seals

  • However, it’s plagued with a few drawbacks, such as poor resistance to ozone, sunlight, and weather. It also has limited resistance to high temperatures and flames.

  • Valve Cover Gasket Supplier Your Ultimate Solution
  • The Pivotal Role of NGK Spark Plugs in Engine Performance
  • A faulty spark plug valve cover gasket can lead to various issues, including

  • The mating surfaces of the head or block must be perfectly clean, flat and smooth.

  • The oil seal surface vertical to the center line of the shaft on the side that does not come in contact with substances to be sealed is called the back face.
  • Regular maintenance is also crucial for the proper functioning of the piston oil seal. This includes checking for signs of wear or damage and replacing the seal as necessary. Failure to do so can result in premature seal failure and costly engine repairs.

  • Valve cover gaskets, typically made from rubber or other elastomeric materials, serve as a critical seal between the engine's cylinder head and the valve cover. They are designed to withstand high temperatures, oil pressure, and the constant vibrations produced by the engine. The rubber in the term refers to their ability to flex and adapt to the irregularities on the mating surfaces, ensuring a tight seal that prevents oil leaks.

  • Synthetic blend oil offers the best of both worlds. It has many of the characteristics of full synthetic oil, but at a much lower price. This type of oil is a mixture of synthetic and conventional base oils, plus some additives, for extra resistance to oxidation and excellent low-temperature properties. Synthetic blends make it easy for drivers to make the switch from conventional to synthetic oil, which is why this type of oil is becoming increasingly popular among today’s savviest drivers. It’s also a great middle ground for drivers who want the added protection and performance of a synthetic oil, but might not be ready to foot the bill for a total switch to full synthetic oil.
