The couplings of drilling rods are another area of technological advancement. These connections must withstand tremendous forces, including torsion, compression, and tension. Advanced thread designs and materials science have led to couplings that are more reliable and easier to maintain Advanced thread designs and materials science have led to couplings that are more reliable and easier to maintain
In terms of cost-effectiveness, fiberglass chemical tanks offer a compelling advantage over other materials
- Rectangular rubber gaskets are used in a variety of industries, including automotive, aerospace, plumbing, HVAC, and chemical processing. They are commonly used as sealing components in machinery, equipment, and systems to prevent leaks and ensure proper function. Some specific applications for rectangular rubber gaskets include

Oil seals, also known as rotary shaft seals, are a type of gasket used to prevent lubricant leakage and contamination in rotating machinery by creating a barrier between the moving and stationary parts.
Oil seals come cataloged as metric oil seals or imperial sized oil seals. The seals can also be custom-made to match the bearings in new types of machinery. They are installed in practically every type of machine including vehicles, protecting all kinds of precision, precisely-fitted ball bearings, sleeve bearings, and roller bearings.

Oil seals come in various shapes to fit the machines and substances to be sealed.
Figure 2 shows the structure and the names of the various components of the most typical oil seal.
The functions of the various components are also indicated in Table 1.
