Another key feature of FRP treads is their resistance to environmental factors. Whether exposed to chemicals, moisture, or extreme temperatures, FRP treads do not corrode, rust, or degrade. This chemical and corrosion resistance makes them suitable for harsh environments such as chemical plants, wastewater treatment facilities, and marine applications. Their ability to withstand UV radiation also ensures that they won’t become brittle or lose their structural integrity when used outdoors.

■Anti-wear agents: Anti-wear agents help protect parts of the engine that are especially susceptible to damage from high temperatures, like cylinder walls, lifters, cams, and piston rings. This additive acts as a protective layer around these components to limit friction in metal-on-metal situations.

As shown in Figure 1, sealing devices come in two types: contact and non-contact.
Oil seals are among the major contact type sealing devices.
APPLICATIONS OF OIL SEALS
Always start by making sure the oil seal is facing the right direction. The oil seal must be positioned with its spring to the side of the medium to be sealed. The oil seal must then be pressed into the bore. It must fit tightly (H8 in the groove is recommended). Use appropriate tools for this, such as an impact socket set, to ensure that the force is applied evenly during pressing. The oil seal must never be hammered into the bore with brute force, but eased in.
Longer seal life can be expected with shafts having a Rockwell (RC) hardness of 30 or more. When exposed to abrasive contamination, the hardness should be increased to RC 60.
Oil seals are used in any industrial application that has a rotating or moving part assembly. This includes:
PTFE
In engine applications, square rubber gaskets are used to seal various components such as valve covers, oil pans, and intake manifolds. These gaskets help prevent oil and fuel leaks, ensuring the engine operates smoothly and efficiently.
