  • If you are installing an o-ring to serve as a backup, make sure you put it on the low-pressure side of the system. This will make the high-pressure side push the o-ring against the backup.

  • Nominal shaft diameter
    d1, mm
  • A temperature range from 75 degrees Fahrenheit to 400 degrees Fahrenheit 
  • In the construction industry, rubber edge gaskets are used in building facades, HVAC systems, and plumbing fixtures to create a watertight seal and prevent air and water infiltration. These gaskets play a crucial role in maintaining the energy efficiency and structural integrity of buildings.

  • Usually, these oil seals are used to seal lubricating oil or grease and contain it within the application, so that moving parts such as bearings are continually supplied with enough lubrication. However, such seals are also used for sealing other liquids, gases, and solids, such as powders or granules.

  • In the automotive industry, thin rubber gaskets ensure the integrity of engine compartments by sealing oil pans, cylinder heads, and fuel lines. In plumbing, they prevent water leaks in pipe connections. In electronics, their insulating properties protect sensitive components from electrical currents and moisture. Aerospace engineering also relies on these gaskets for sealing aircraft cabins, fuel tanks, and hydraulic systems.

  • Furthermore, Double Platinum Spark Plugs are designed to be compatible with a wide range of vehicles, from small sedans to large trucks. This versatility makes them an attractive option for car enthusiasts and professional mechanics alike. Whether you're looking to squeeze every last bit of performance out of your ride or simply want to ensure optimal engine health, Double Platinum Spark Plugs are an investment worth considering.
  • • Total eccentricity, etc.

  • Steel or cast iron is generally used as the housing material.
    Aluminum alloys and resin (materials with a large difference between the linear expansion coefficients) demand sufficient consideration (as there is a risk of failure due to the increased clearance with the oil seal at high temperatures).

  • Rubber oil seals have to perform in extreme conditions. Therefore, we accommodate all relevant conditions (mechanical and thermo-chemical phase) to maintain the integrity of the rubber oil seal in these circumstances.

  • There are several types of spark plugs, each tailored to specific engine requirements. Conventional spark plugs, with a single ground electrode, are the most common. Iridium and platinum spark plugs, known for their durability, have multiple electrodes and longer lifespan. Double iridium or double platinum spark plugs further enhance efficiency and longevity.

  • As shown in Figure 1, sealing devices come in two types: contact and non-contact.
    Oil seals are among the major contact type sealing devices.

  • Role of Rubber Oil Seals: Versatility and Performance

  • The first material that we are going to look at is Nitrile Buna- N 70 or NBR for short. 

  • Resistant to H25 and CO2. 

  • Another important factor to consider when choosing spark plugs for your MK7 GTI is the electrode material. The electrode material can vary between spark plugs and can have an impact on the performance of your engine. Copper, platinum, and iridium are common electrode materials used in spark plugs. Iridium spark plugs are often preferred for performance cars like the MK7 GTI due to their durability and ability to maintain a stable spark.
