  • Figure 14.1. Shaft seals (DuPont Dow Elastomers).

  • 2. Industrial Machinery Metal-to-oil seals are used in a variety of industrial machinery, such as pumps, compressors, and turbines, to ensure that fluids remain contained within the system.
  • Undo most of the fixings, then support the sump by hand while you remove the rest.
  • Metric oil seals are designed to fit in metric-sized shafts and bores, providing a secure seal to prevent oil leakage. These seals are typically made of rubber, silicone, or PTFE (polytetrafluoroethylene) materials that offer excellent resistance to oil, water, and other fluids. The choice of material for the seal depends on the specific application and operating conditions, such as temperature, pressure, and speed.

  • Common causes of oil seal failure

  • You may need to turn the crankshaft so that it protrudes less. Turn the front pulley bolt with a spanner or socket.

  • Silicone rubber gaskets are also known for their excellent weather resistance. Unlike traditional rubber gaskets, which may degrade when exposed to UV rays and harsh weather conditions, silicone rubber gaskets remain unaffected. This makes them ideal for outdoor applications, such as in outdoor lighting fixtures, solar panels, and marine equipment.

  • In addition, the axia spark plug is designed with a special electrode shape that allows for a more efficient burn of the air-fuel mixture. This design helps to optimize the engine's performance and power output. The axia spark plug also has a superior insulator that helps to prevent fouling and misfiring, ensuring smooth and reliable engine operation.

  • ERIKS type GV (type C according to DIN) is equivalent to type M, but is a heavy-duty version with a double metal casing. This can be a useful solution with larger diameters in more demanding applications. There is also a version of this type with a dust lip; the GVST (type CS according to DIN).

  • Metal

  • A square rubber gasket is a vital component in various mechanical applications, providing a seal between two surfaces to prevent leakage or contamination. These gaskets are commonly used in machinery, engines, piping systems, and automotive applications.


  • In the intricate world of internal combustion engines, there exists a vital component that ensures smooth operation and longevity. This component is none other than the piston oil seal. Often overlooked yet absolutely indispensable, the piston oil seal serves as a barrier between the high-pressure oil compartment within the engine and the external environment.
  • In conclusion, die-cut silicone gaskets are a testament to the power of combining advanced manufacturing techniques with superior materials. Their unique combination of resilience, adaptability, and performance characteristics has made them indispensable in numerous industries. As technology continues to evolve, the role of die-cut silicone gaskets in sealing solutions is expected to grow even further, playing an increasingly vital role in ensuring safety, efficiency, and reliability in diverse applications.
  • Oil seals are commonly made from materials like nitrile rubber (NBR), which offers excellent resistance to oils, greases, and a wide range of temperatures.

  • In the realm of marine engines, the significance of spark plug wires cannot be overstated. These critical components serve as the conduits through which electrical energy is transmitted from the ignition system to the spark plugs, igniting the air-fuel mixture and propelling the boat forward. The importance of high-quality marine spark plug wires is underscored by their direct impact on engine performance, fuel efficiency, and overall reliability.

  • The black color of these spark plugs is a result of carbon buildup, which is a common issue that can occur over time due to normal engine wear and tear. This carbon buildup can negatively impact the performance of the spark plug, leading to misfires, rough idling, and poor fuel efficiency. It is important to regularly inspect and replace black spark plugs to ensure optimal engine performance.


  • Summary

  • oil seal

  • Vulcanizates of several fluoroelastomers, listed in Table 14.1, were exposed to a standard 5W-30 engine oil, ASTM Service Fluid 105, for up to 6 weeks at 150°C (302°F).5 The oil was changed weekly, but was not aerated. Retained elongation was measured after exposure for 1, 2, 3, and 6 weeks; data are shown in Fig. 14.3. The results indicate that bisphenol-cured FKM-A500 VDF/HFP copolymer, FKM-B600 VDF/HFP/TFE terpolymer, and peroxide-cured FEPM-7456 TFE/P/VDF terpolymer lost most of their original elongation over the course of the test exposure, indicating considerable additional cross-linking occurred by reaction with amine- and phenol-containing oil additives. The other fluoroelastomers showed better retention of elongation, being much less susceptible to additional crosslinking. Note that FEPM-7456 contains a high level of VDF (about 30%), while FEPM-7506 contains a relatively low VDF level (10–15%) to serve as cure site for bisphenol curing. The other FEPM types contain no VDF.

  • Temperature - Just like pressure, the temperature that your oil seal will be operating in must be known so that you can choose one that can withstand the heat or cold. PTFE have the widest range of temperature, making them useful for machines who can see usage in extreme weather or elements.

  • Whether you are a car enthusiast looking to upgrade your spark plugs or a mechanic in need of reliable ignition components, porcelain spark plugs are a solid choice that can help keep your engine running smoothly.
