Depending on the application, premium lip materials may need to be used, such as Ethylene-acrylic (Varmac®). This material features good abrasion and dry running capabilities, higher heat capabilities than nitrile and polyacrylate, and better low-temperature performance than polyacrylate.
- Your engine sounds louder than normal. A rattling noise might signal that your engine could benefit from denser motor oil, i.e., high mileage oil.
- One essential component of a vehicle's engine that often goes unnoticed is the spark plug. The spark plug plays a crucial role in igniting the air-fuel mixture in the engine's combustion chamber, which ultimately powers the vehicle. While most spark plugs are a standard silver color, there is a particular type known as the black spark plug that has been gaining popularity among car enthusiasts.
Investing in quality seals will benefit you and your machine in the long run. The cost of replacing oil seals will be higher as cheaper alternatives are constantly being purchased. Not to mention, the efficiency and quality of low-cost oil seals may not be reliable.


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.
Oil seals come in various shapes to fit the machine or substance for sealing.
For this reason, when designing a machine, it is important to select the oil seal that is right for that machine.
Next time, we will explain the key points to consider when selecting your oil seal.

There are three main different types of headlights. These car headlights types are Halogen, Xenon & LED headlights. Each work quite differently in the way they produce light and therefore produce different types of light on the road.

2. PRESSURE: Oil Seals cannot endure a lot of pressure. You need to understand your machinery’s pressure capabilities and ensure you use the correct seal to withstand its pressure levels.
