- In conclusion, the rear shock absorber oil seal is more than a mere sealant; it is a vital component that ensures your safety on the road and the longevity of your vehicle's suspension system. Regular checks and prompt maintenance can save owners from unforeseen inconveniences and hefty repair bills. As they say, an ounce of prevention is worth a pound of cure, and nowhere is this truer than in the world of automotive care.
Oil seals can also be known as rotary shafts seals, shaft seals, lip seals, elastomeric seals, and more.

What are Oil Seals?
Oil Seals without Spring
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.
All are fitted with a spring to preload the sealing lip. All these types are for non-pressurised or low-pressure applications up to 0.5 bar for diameters of a limited size. For diameter of 500 mm or more, the maximum pressure is 0.1 bar. For higher pressures, special types or PTFE lip seals can be used.

There are several key factors to consider when you are selecting the oil seals for your next project to ensure that you protect your machinery from immediate and long-term damage.
EPDM
Oil seals are used in a great many machines.
When it comes to replacing spark plugs in your car, cost is always a factor to consider. New spark plugs can vary in price depending on the brand, material, and quality. It is important to understand the factors that contribute to the cost of spark plugs in order to make an informed decision.
If these criteria are met, damage of the machine can be reduced, the time needed to replace the oil seals when performing repairs can be shortened, and the machine can be used for a longer period of time.
