- 2. **Reduced Emissions** The high-energy spark created by A7TC spark plugs results in more complete combustion, reducing harmful emissions and improving fuel economy.
- The Importance of Steering Rack Oil Seal A Vital Component for Vehicle Stability
- Diesel spark plugs, an often-overlooked yet essential component in diesel engines, play a pivotal role in ensuring optimal performance and efficiency. Unlike gasoline engines that rely on spark plugs for ignition, diesel engines use compression ignition; however, the term diesel spark plugs refers to glow plugs, which serve a similar purpose.
We have different types of oil seals that are designed specifically for various industries, like aerospace, automotive, oil & gas, electronics, chemical analysis, food & beverage, engineering, and so on. Some of our other custom products are bellows, insulators, labware, bushings, ball valve seats, tubes, rods, films, and sheets. Contact us today to make sure you choose the best component for your application.
- When choosing a Half Moon Valve Cover Gasket, quality is paramount
half moon valve cover gasket. A durable material like rubber or silicone, known for their resistance to heat and pressure, is typically preferred. Regular inspection and timely replacement of worn or damaged gaskets are essential to maintaining the health of the engine.
If the shaft or housing gets damaged, it must be repaired. If you replace only the oil seal, but the shaft or bore remain damaged, then there is a chance of premature failure or leakage. You can easily repair the shaft, for example using an SKF Speedi-Sleeve.

(2) When the ambient temperature is high, polyacrylate or silicon, fluorine, and silicon fluorine rubber should be selected. And should try to lower the oil temperature in the tank. When the operating temperature is too low, cold-resistant rubber should be used.


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).
It is generally used in the union of two lubricated parts, so that it hermetically seals both sides. Therefore, it guarantees the proper engine operation and helps to maintain the vehicle’s distribution system in better condition.
Right Valve Cover Gasket: Essential Component for Engine Integrity
Conventional oil is the most commonly used type of oil. It is ideal for light-duty, late-model cars with low to average mileage and a simple engine design.
Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.
(See Figure 3.)
Improper installation can cause your oil seal to malfunction. While being tapped into place, it can become tilted or misaligned in the bore. That being said, setting it up correctly will help ensure that the sealing process is effective.
Operating temperatures for engine oil seals (see Fig. 14.11 and cross-section of lip seal with garter spring in Fig. 14.22) vary widely, depending on engine design and location within the engine. Typically, the rear crankshaft seal is subjected to much higher temperatures than the front seal. Oil sump temperatures vary considerably, depending on provisions for oil cooling. This allows use of hydrogenated nitrile (HNBR), silicone, or acrylic elastomers for some seals in relatively low-temperature environments (120–140°C or 250–284°F). Standard fluoroelastomers (FKM), bisphenol-cured VDF/HFP/TFE terpolymers with 68–69% fluorine content, perform well in oil service up to about 160°C (320°F). More resistant fluoroelastomers are necessary for reliable long-term performance in more severe environments.
The major cause of extrusion and nibbling is stress caused by high pressure. This is commonly noticed when the oil seal has a chipped or nibbled look. In fact, in some cases, the surface of the seal tends to peel on its own, which makes it have a shaved look. What the stress does is that it increases the clearance gap between the mating edges, which causes the seal to get entrapped, and then leads to severe physical damage.
To do this, turn the engine with a socket on the crankshaft pulley bolt until the rotor arm is pointing to the plug contact of the timing cylinder (usually No. 1, check in the car service manual), and the timing marks on or behind the pulley show exactly top dead centre ( TDC ).
