Another critical benefit is the longevity of fibreglass tanks. With proper maintenance, these tanks can last for decades, providing a long-term storage solution. They are less susceptible to leaks, which not only prevents product loss but also reduces the risk of environmental contamination—a significant concern in today’s eco-conscious world. The non-porous surface of fibreglass minimizes the likelihood of liquid permeation, which is a common issue with other materials.

A standard oil seal consists of an outer circular metal disk with an inner flexible rubber which is affixed to the metal during vulcanization. The bonded seal has no loose parts to allow leakage of oil or ingress of any contaminants. This kind of seal is more accurate, and can easily be fitted into a smaller space. An example is shown in Figure 2.9.


5. Keep it clean
0.4 to 1.6 μmRa,
1.6 to 6.3 μmRz
2. For rubber O.D. wall type:
1.6 to 3.2 μmRa,
6.3 to 12.5 μmRz
(Firmly affixes the oil seal and prevents leakage through the seal O.D.)
Reinforced GVP design for larger diameters, with rotation speeds of up to 15 m/s and pressure of 3-4 bar
Oil seals, which are also referred to as radial shaft seals, rotary shaft seals, grease seals, or fluid seals, are used to close the gaps between fixed and moving parts of mechanical equipment. They are put between moving and stationary mechanical parts to make sure that moisture, contaminants, corrosive materials, and abrasives don’t cause any damage to these parts.
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.
Overall, black spark plugs are a common issue that can occur in internal combustion engines. It is important to regularly inspect and replace spark plugs to ensure optimal engine performance and prevent more serious issues down the line. By addressing the root causes of black spark plugs, such as a rich air-fuel mixture, oil leakage, and overheating, you can keep your engine running smoothly and efficiently.
You have to consider the speed at which the shaft will be moving, the housing bore, and the runout. These are important to make sure that you choose an oil seal that will not be exposed to unconducive abrasions.
