2. Household Appliances Many common appliances, such as washing machines and food processors, utilize ribbed belts to facilitate motion and power transfer.
- The primary function of a head gasket is to prevent the mixing of coolant and oil with the combustion chamber's high-pressure gases. It also maintains the necessary compression ratio, which is crucial for the engine's ability to generate power. Without a head gasket, the engine would suffer from leaks, leading to a decrease in efficiency, overheating, and potentially catastrophic failure.
- Undersized Installation Tool: If the installation tool’s driving diameter is too small, it can deform the seal during installation. Choose a tool with an appropriate driving diameter to avoid this problem.
The last step involves the actual pressing-in of the seal. There are tools and tool kits available that can help with seal installation. Their biggest benefit is that they apply a very uniform force to the seal case, eliminating the possibility of the seal seating in any way other than flush.
In addition to selecting the right type of oil seal, it is essential to consider the operating conditions of the equipment. Factors such as temperature, pressure, and speed can impact the performance and longevity of the seal. Choosing a seal that is rated for the specific operating conditions will help ensure reliable sealing and extended service life.
The depth of the bonded seal can be less and the space between the bore and the outside diameter can be changed for ease of fitting. The bonding of rubber to metal is an important factor to be considered in the manufacture of such seals and should be considered carefully, since failure of the bond will cause the seal to fail. The metal case of the oil seal is usually made from mild steel of deep drawing quality which enables blanking, punching, stamping of the steel to the required dimensions.

There may be a thick spacer gasket between two thin paper ones. Check the spacer for cracks. If it needs replacing, be sure the new one is the right thickness, because this governs the fuel-pump lever stroke .
Assembling the oil seals is only possible with the right assembly tools. Due to the high risk of damage during assembly, it is important that you have tools with which you can work carefully. A bearing fitting tool set is ideal.
Out-gassing
These types are made with a metal outer case and a PTFE lip. They are suitable for a wide range of temperatures from -90 °C to +260 °C.These lip seals can also be used for higher pressures of up to 10 bar (special types up to 25 bar) and rotational speeds of up to 40-45 m/s. Certain grades of PTFE are suitable for use in pharmaceutical and food applications. One important point is that PTFE lip seals do require a shaft with a harder, smoother finish.
