- Silicone rubber gaskets are also known for their excellent weather resistance. Unlike traditional rubber gaskets, which may degrade when exposed to UV rays and harsh weather conditions, silicone rubber gaskets remain unaffected. This makes them ideal for outdoor applications, such as in outdoor lighting fixtures, solar panels, and marine equipment.

- Perhaps one of the most significant advantages of cork rubber gaskets is their eco-friendliness. Cork is a renewable resource that is harvested from the bark of cork oak trees, which are grown in sustainable forests. In addition, cork rubber gaskets are typically made using non-toxic materials, making them an environmentally friendly alternative to other types of gaskets.

Oil seals, also referred to as shaft seals, are widely used to prevent the leakage of medium (such as oils and grease) along a rotating shaft. This leak prevention is primarily achieved by the sealing element which can be made from a wide range of materials that are chosen according to each application. They are commonly used in gearboxes, hydraulic cylinders, and related components.

How to Choose the Right Oil Seal for Your Industrial Application
How does an Oil Seal Work
Regular inspection and maintenance of oil seals are essential to identify signs of wear, damage, or leakage. Proper lubrication and adherence to recommended service intervals can help extend the lifespan of oil seals. When replacement is necessary, selecting the correct seal type and ensuring proper installation are critical to maintaining the integrity and performance of the equipment.
Oil seals are made out of nitrile synthetic rubber with steel stiffener rings. Other rubbers such as viton, silicon, neoprene or poly acrylic can be used for specific applications. The stiffener rings may be stainless steel or brass where highly corrosive fluids are to be sealed. Springs are generally made of spring steel to IS: 4454:Gr.ll or from stainless steel or bronze for corrosion resistance

The sealing lip is always made of a rubber or synthetic material. For oil seals with a rubber outer case (R, RST, GR, GRST), the rubber quality of the sealing lip and the outer case are the same.

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.
If the car has a manual gearbox , select first or reverse gear and put the handbrake full on. Otherwise, disconnect the battery and remove the starter motor .
