The materials used in manufacturing hydraulic seals are also vital to their performance. Common materials include rubber compounds, polyurethane, and PTFE (Polytetrafluoroethylene). Each material offers different advantages and is selected based on the operating environment. For example, PTFE seals are highly resistant to chemicals and extreme temperatures, making them ideal for demanding applications.

Material Selection

One common issue that can arise with hydraulic jacks is a leak in the seals. If you notice that your jack is not lifting as easily as it should, or if you see oil leaking from the jack, it is likely that the seals need to be replaced. Fortunately, seal kits are readily available for most hydraulic jacks, including 3-ton models.

It is suitable as an alternative to titanium dioxide when higher acid resistance is required, such as in adhesive joints and sealants. 

1. What is titanium dioxide?

In a study published in 2022 in the journal Particle and Fibre Technology, researchers examined the impact of maternal exposure to titanium dioxide nanoparticles in newborn offspring mice. They found that “a chronic exposure to TiO2 NPs during pregnancy alters the respiratory activity of offspring, characterized by an abnormally elevated rate of breathing.” Breathing was also shown to be “significantly and abnormally accelerated,” and the ability for neural circuitry to effectively adjust breathing rates was impaired. The researchers concluded: “Our findings thus demonstrate that a maternal exposure to TiO2 NPs during pregnancy affects the normal development and operation of the respiratory centers in progeny.”
