Heavy-duty tow bars are robust devices designed to withstand high stress and significant weight. Typically constructed from high-strength steel or other durable materials, these tow bars are engineered to handle the demands of the trucking industry. Depending on the specification, a heavy-duty tow bar can handle loads ranging from several thousand pounds to tens of thousands of pounds, making them suitable for large trucks, buses, and specialized vehicles.

  • It is resistant to high temperatures 
  • Spark plug technology has evolved over time, with various types designed for different engines and performance requirements. For instance, platinum and iridium-tipped spark plugs offer longer life and better performance due to their superior resistance to wear For instance, platinum and iridium-tipped spark plugs offer longer life and better performance due to their superior resistance to wear For instance, platinum and iridium-tipped spark plugs offer longer life and better performance due to their superior resistance to wear For instance, platinum and iridium-tipped spark plugs offer longer life and better performance due to their superior resistance to wearspark plug motor. Some modern engines even use multiple spark plugs per cylinder for enhanced ignition.

  • Regular inspection and maintenance of oil pan seals, turbo oil seals, and gasket seals are essential to identify signs of wear, damage, or leakage. Proper lubrication and adherence to recommended service intervals can help extend the lifespan of these seals. When replacement is necessary, selecting the correct seal type and ensuring proper installation are critical to maintaining the integrity and performance of the engine.

  • In conclusion, the rear valve cover gasket, though seemingly insignificant, is a critical part of an engine's health. Its function is not just to prevent oil leaks but also to maintain the cleanliness and lubrication necessary for smooth engine operation. Hence, understanding its importance and ensuring its proper maintenance is a must for every vehicle owner or mechanic. Remember, prevention is always better than cure, and a healthy engine starts with a reliable rear valve cover gasket.
  • Sealing Material: The material used in the seal lip should be resistant to the operating temperature range, chemicals, lubricants, and pressures in your application.

  • A double oil seal, also known as a tandem seal or a dual seal, consists of two sealing elements placed in series. This design offers a two-layered defense against contamination ingress and fluid egress, thereby enhancing the overall sealing performance. The primary seal acts as the first line of defense, while the secondary seal serves as a backup, providing redundancy in case the primary seal fails.

  • Environmental Considerations and Compliance

  • The durability of PTFE oil seals is another significant advantage. Due to their resistance to wear and tear, they require less frequent maintenance and replacement, leading to cost savings in the long run. They also offer superior resistance to abrasion, which is crucial in applications where there is continuous contact with abrasive particles.

  • When the total eccentricity is excessive, the sealing edge of the seal lip cannot accommodate shaft motions and leakage may occur.
    Total eccentricity is the sum of shaft runout and the housing-bore eccentricity.
    Total eccentricity, shaft runout and housing-bore eccentricity are generally expressed in TIR (Total Indicator Reading).

  • Installing and replacing the 75x100x10 oil seal is a straightforward process that can be done by maintenance personnel with basic mechanical skills. It's important to ensure that the shaft and housing where the oil seal will be placed are clean and free of any debris or damage. Proper lubrication of the shaft is also crucial to prevent premature wear of the oil seal.


  • We highly recommend to use special tools when installing oil seals without a plastic sleeve. You can find the advice around the right tool from the manufacturer. 

  • Chemical Attack

  • The metal case serves as the oil seal’s exterior or frame, providing rigidity and strength to the seal. The case material selection depends on the environment in which the seal will operate. Often, the same rubber material used in the seal element covers the case to help seal the exterior of the oil seal in the housing bore.

  • No single physical property of rubbers is responsible for the successful performance of an oil seal or ‘O’ ring. The ultimate tensile strength, breaking elongation, modulus, shore hardness, creep and stress relaxation in tension and compression loads are all important physical properties that characterize a seal or ‘O’ ring. Compression strength and set together with stress relaxation or decay are important for effective sealing. The difference in these properties in a swollen seal is highly critical. An optimum swelling value in a fluid medium is a desirable feature. De-swelling decreases the seal pressure against the wall of the housing where the seal is fixed, leading to leakage. Over swelling minimizes the physical properties of the rubber. Seals made of polysulfide rubbers have extreme fuel resistance but undesirably high compression set. The effect of temperature on the seal is an important factor. Swelling under stress can increase at higher temperatures and a suitable compounding technique should be adopted to reduce this effect.

  • The Significance of the B20 Series Valve Cover Gasket
  • In conclusion, while iridium spark plugs carry a higher price tag than traditional models, their increased longevity, performance enhancements, and potential fuel savings offer a compelling value proposition. As with any automotive part, the decision to invest in iridium spark plugs should be based on individual needs, driving habits, and the specific requirements of one's vehicle. For those who prioritize peak engine performance and seek a long-term, cost-effective solution, iridium spark plugs are undeniably worth considering despite their elevated price point.
  • Choosing the right spark plug for your motorbike is crucial. Different types of spark plugs, each with varying heat ranges and electrode materials, can significantly affect your bike's performance Different types of spark plugs, each with varying heat ranges and electrode materials, can significantly affect your bike's performance Different types of spark plugs, each with varying heat ranges and electrode materials, can significantly affect your bike's performance Different types of spark plugs, each with varying heat ranges and electrode materials, can significantly affect your bike's performancemotorbike spark plugs. For instance, a colder spark plug can help prevent pre-ignition in high-performance engines, while a hotter plug can aid in fuel economy and emissions control.
  • Metal Coverd Rubber
  • Oil seal manufacturers also play a critical role in innovation and product development. As technology advances and new materials become available, manufacturers continually strive to improve the performance and efficiency of their seals. This may involve designing seals with lower friction, higher temperature resistance, or better chemical compatibility to meet the evolving needs of their customers.
