Polyacrylate Oil Seals - Mostly selected for automotive and transmission uses, polyacrylate seals are able to withstand fuel, oil, ozone, sunlight and weather when used. With cars exposed to all these different fluids and elements, they are the perfect choice. However, they should not be used in low temperatures, as their flexibility weakens when cold.

Low coefficient of friction poor elastic properties not wear resistant if used by dynamic applications
Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.
Most standard oil seals have to comply with the DIN 3760 and ISO 6194 standards. Different standard types of oil seals are available that comply with these requirements.
The LS1 engine, a popular choice among car enthusiasts and professionals alike, owes much of its power and efficiency to the precision and performance of its spark plugs. These vital components play a crucial role in igniting the air-fuel mixture within the combustion chamber, which in turn propels the vehicle forward with remarkable force.4. SHAFT SPEED: As different shafts move at different speeds you need to consider the runout, the housing bore, and oil type being sealed. Ensure you select a seal that will not suffer from abrasions or spiralling.
Refit all pipes and wires, and the air cleaner. Start the engine and check for oil leaks.
In recent years, manufacturers have also introduced double platinum and double iridium spark plugs. These plugs feature two layers of platinum or iridium, providing even greater durability and performance. While these plugs are more expensive than their single-layer counterparts, they are often worth the investment for drivers looking to maximize their engine's performance.
