- A thermostat gasket, typically made from rubber or silicone, is placed between the thermostat housing and the engine block. Its primary function is to create a watertight seal, preventing coolant from leaking out and ensuring a smooth flow through the engine. It acts as a barrier, maintaining the integrity of the cooling system and preventing any contamination that could disrupt the delicate balance of temperature within the engine.
- Furthermore, a durable front valve cover gasket is essential for long-term engine health
- 7. Perfluoro rubberThe high temperature of perfluoro rubber is superior to that of silicone rubber. It has good
- Silicone rubber gaskets also exhibit excellent chemical resistance, meaning they can withstand exposure to a wide range of chemicals without deteriorating. This property makes them ideal for use in harsh environments where chemicals are present, such as chemical processing plants, laboratories, and pharmaceutical manufacturing facilities.

- 3. Sealant Application Apply a sealant to the gasket surface to enhance the sealing performance. Use a silicone-compatible sealant that is recommended by the gasket manufacturer.
- In conclusion, the oil seal 12 22 5 is a small but essential part that plays a significant role in the performance and longevity of industrial machinery and automotive systems. Its ability to prevent oil leakage, maintain lubrication, and protect the equipment from external factors makes it a crucial component that should not be overlooked.
- Introduction
The care taken during the installation process will pay off by allowing the seal to work quietly and operate efficiently behind the scenes of your application.
Some aspects to consider when selecting this component are:
The sealing element makes up the interior of the oil seal, and the materials commonly used are:

- Do not top up engine oil and do not start the engine until four hours after assembly. This is advised by both Elring and Victor Reinz to allow the new oil seals to form to the shaft.

The range of uses of peroxydically cross-linked EPDM includes in hot water and steam seals. EPDM is also very resistant to ageing and ozone. Compared with the usual types of synthesis natural rubber it has good resistance to cold temperatures. EPDM is not resistant to aliphatic or aromatic hydrocarbons or mineral oil products. Resistance to chemicals, and also to oxidising agents, is very good. Temperature range from -50 °C to +140 °C depending on type.
As can be seen from the seal cross-section shown in Fig. 14.2, shaft seals are complex shapes that require advanced mold design and molding techniques (see Section 7.3 for discussion of fluoroelastomer molding). For some time, most shaft seals were made in the United States by compression molding. Injection molding of shaft seals is prevalent in Europe, and is being used increasingly in the United States. An advantage of compression molding is that preforms (usually rings cut from extruded tubing) are used that closely approximate the amount of stock required for the final parts, so compound waste is minimized. For injection molding, the amount of cured stock in the central sprue and runner (actually a thin sheet leading to the seal lip) is often large compared to the stock required for the final part, so the waste of high-cost fluoroelastomer may be high. Such waste is reduced in modern injection molding designs.
These are now the current and most recent innovation that is taking over from the HID and Halogens. The LEDs employ the diodes technology where they produce light when electric current excites their electrons. They require low power and energy and still produce brighter light than halogen headlights which also leads to LEDs’ longer life-span. Their diodes can be manipulated into various shapes providing unique configurations. With LED technology, the vision is much improved and more focused. Although the initial cost of HID and halogen bulb is less than LEDs, the operational and maintenance costs of LED are significantly lower. LEDs, having a longer life, reduce maintenance and lamp replacement cost. Because LEDs need to be replaced less frequently, the owner spends less on new lamps and the labor needed to change them. LEDs also consume less energy; thus the overall cost of a LED system can be significantly lower than that of conventional lighting systems.

FKM or FPM, which is in well-known brand Viton™, can withstand higher liquid temperatures of up to 180 ˚C. FKM is highly resistant to strong acids and bases, as well as to synthetic oils and greases. Glycol-based oil and grease, however, can also damage FKM.
