- Adaptability Different geological formations require specific materials. Choosing the right tools can help overcome challenges posed by varying rock types and conditions.
Remove the distributor cap . Before removing the distributor (See Removing and refitting the distributor ), mark the position of the rotor arm so that you can refit it just as it was.

Another type of seal design has the metal encased in rubber (Figure 2.11).
Oil seals, also known as grease seals or shaft seals, are essential components in many machines and systems. They play a crucial role in preventing the leakage of oil and other lubricants, ensuring the smooth and efficient operation of various mechanical parts.

Use a piece of wood to scrape off all traces of the old gasket from the head and cover. If total removal proves difficult, use a broad screwdriver blade, but take care not to scratch the seating.
Oil seals are made from multiple compounds and materials. Some of the oldest, still in use today, are leather and felt compounds. The trend in mass production, however, has seen a move towards synthetic rubber or elastomers. Nitrile is by far the most popular material but developments in PTFE have created a surge of interest in buyers needing seals for high-speed shaft rotation applications. Viton is taking over from the polyacrylic and silicone, as it works better in high-temperature applications and has a high-resistance to abrasion and harmful chemicals.
To act as a barrier and prevent dirt, contamination and other external entities from entering the system containing the lubricating oil.
Most conventional oil seals are designed only to withstand very low-pressure applications (about 8 psi or less). If additional internal pressure is present or anticipated, pressure relief is necessary.

ERIKS also supplies the types GR and GRST. These are virtually identical to the types R and RST, except in this case the metal inner ring is also completely encased in rubber. ERIKS uses FKM rubber here as standard, so these seals are ideal for use in acidic environments.
