3. Increased Operating Pressure A change in the pressure gauge reading can signify a seal issue. If the pressure is fluctuating unexpectedly, it may be due to fluid bypassing the seals.

Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.

3. Aerospace High-pressure oil seals are essential in aerospace applications, where they are used in engines and landing gear, where they withstand not only high pressures but also extreme temperatures and environmental conditions.

However, there are also some drawbacks to air conditioners with a pipe. One limitation is that the length of the pipe can affect the efficiency of the unit. Longer pipes can decrease the airflow, which may reduce the cooling capacity of the air conditioner. Additionally, the need to expel hot air outside can be a challenge in some situations, such as in apartments or buildings with strict regulations on external modifications.
