ptfe oil seal. This makes them suitable for use in applications where other types of seals may be damaged by exposure to chemicals.
Hydrogenated nitrile natural rubber (HNBR)

Moreover, the housing is designed to handle high-pressure conditions typical in reverse osmosis systems. It can withstand the pressure exerted during water filtration, preventing any leaks or failures that could compromise the purification process. This pressure resistance is critical, as even minor leaks can lead to a significant decrease in system performance and eventual water quality issues.

If this is not possible, you may be able to fit the lower retaining bolt into the upper mounting support, to hold the engine level. Or the gearbox may have to be jacked up and supported.
The rubber material used in the oil seal should be selected based on the operational temperature and substance to be sealed.
Table 5 lists the major rubber materials along with their operational temperature ranges.
Note that it is necessary to check the compatibility with fluids.
<N.B.>
Extreme pressure additives are compounds added to the lubricant. They are activated by heat and chemically react against rubber, which deteriorates rubber properties. For this reason, it is necessary to check for compatibility with rubber materials.
