- Diesel engines operate on a principle known as compression ignition, where air is compressed in the cylinder until it reaches a high enough temperature to ignite the fuel. The heat generated by the compression of the air is usually sufficient to ignite the diesel fuel. However, in some cases, especially in cold weather or when the engine is under heavy load, the temperature of the air in the cylinder may not be high enough to ignite the fuel. This is where the diesel engine spark plug comes into play.

- In conclusion, the humble 12x22x5 oil seal might appear as a mere afterthought in the grand scheme of mechanical design. However, its significance cannot be overstated—it stands as a testament to the idea that even the smallest components can have the most profound impact on an engine's health and longevity. With a mere 5% tolerance rate, it epitomizes the engineering principle that precision equals perfection. As engineers continue to push the boundaries of what machines can do, components like the 12x22x5 oil seal will remain silent guardians, ensuring that the heart of those machines continues to beat strongly and efficiently.

- Now, let's consider the pricing. Iridium spark plugs typically retail at a premium compared to standard options. Depending on the brand and application, one could expect to pay anywhere from a few dollars more per plug to potentially several times the cost of regular spark plugs. While this might seem steep at first glance, it's crucial to factor in the extended interval between replacements. If an iridium plug can last twice as long as a standard plug, the effective cost over time may not be as dramatic If an iridium plug can last twice as long as a standard plug, the effective cost over time may not be as dramatic

Many – too numerous to list, covering a vast range of designs, sizes, and materials suitable for a never-ending range of applications. Some designs conform to International Standards such as BS1399 and DIN 3760 for metric sizes and seal types, but the majority have been manufactured to suit particular applications – hence the enormous selection available. This blog is intended to assist in this selection and will consider seal type, materials, and sizes.
Shaft oil seals are an essential component in machinery and equipment used in various industries. They play a crucial role in preventing the leakage of fluids and keeping contaminants out of the system, ensuring smooth operation and prolonging the lifespan of the machinery.
As an example, this oil seal has a part number that corresponds to a Shaft Size of 3”, a Bore Size of 4”, a Width Size of 0.625”, a Style of TB2, and is made of Viton material. Conversely, the same size oil seal in Metric has a Shaft Size of 76.20 mm, a Bore Size of 101.60 mm, and a Width Size of 15.88 mm.


However, the new variant also comes with less good properties. Namely less flexibility and less resistance during assembly. Most damages therefore occur during the installation of PTFE oil seals.
VMQ, also known as silicone, is also used for oil seals, but this is less common because the mechanical strength of VMQ is low and this material has poor wear-resistance This makes it less suitable for dynamic applications, but it can withstand fairly low and high temperatures from -60 °C to 200 °C. Many types of VMQ are also suitable for contact with pharmaceutical and food products, so VMQ is an option worth considering. VMQ oil seals are usually available on request.

Materials Used to Make Oil Seals
What material are oil seals made from?
Our rubber seals are used in the following industries:
The dimensions of the 25x47x7 oil seal refer to its inner diameter, outer diameter, and thickness, respectively. These measurements are important in ensuring a proper fit for the seal in the machine or engine it is intended for. By providing a secure seal between moving parts, the oil seal helps to maintain proper lubrication in the machine and prevent the loss of oil.
