Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.

Another popular option is reverse osmosis (RO) filtration. This advanced method pushes water through a semipermeable membrane, which blocks larger molecules and contaminants while allowing clean water to pass through. RO systems are highly effective in removing dissolved salts, heavy metals, and microbial pathogens. They are particularly beneficial in areas where water sources are heavily contaminated, providing a reliable solution for safe drinking water.
