Hebei Hankai double lip oil seal

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.

Wiper oil seals, commonly referred to as lip seals or simply oil seals, are mechanical seals used to keep lubricants in and contaminants out of machinery. They are typically made from durable materials such as rubber or elastomers, designed to withstand high pressures and temperatures. The primary function of these seals is to maintain a barrier that prevents the escape of oil, while also preventing dirt, dust, and other contaminants from infiltrating the system.
