In construction and civil engineering, chemical resin bolts are often used to secure machinery, hangers, brackets, and other fixtures to masonry, concrete, and even stone surfaces
Table 2 a): Common types of oil seals (with spring)

O-rings, which are also referred to as oil seal rings or oil ring seals, are designed to join two parts and ensure that no air, moisture, or gas is allowed to pass through. They are usually inserted into a groove and manufactured to resist pressure. The resistance is what stops foreign elements from entering or leaving the joining.
Seals, including oil seals, have undergone a great development in recent years and are totally unlike the original product. PTFE has taken over the oil seals market for modern engines mainly because traditional oil seals started causing more and more problems. Such as evaporation of chemical plasticisers from the elastomeric material, which eventually caused engine oil leakage. Now, the focus is more on durability and frequency of servicing.
Regular inspection and replacement of oil seals are also important for preventing leaks and maintaining the efficiency of high-pressure systems. Over time, the seals can wear out or become damaged, leading to oil leaks and potential system failures. By monitoring the condition of the seals and replacing them as needed, operators can prevent costly downtime and repairs.
