In addition to preventing oil leakage, cylinder oil seals also help to prevent contamination. Contaminants such as dirt, dust, and moisture can enter the cylinder and cause damage to the internal components. This can lead to reduced efficiency, increased maintenance costs, and a shorter lifespan for the machinery. By creating a tight seal around the cylinder shaft, oil seals help to keep contaminants out and protect the internal components from damage.

Another technique involves the use of durable water repellent (DWR) treatments. These treatments are applied to the outer surface of wool fabrics to create a protective layer that causes water to bead up and roll off. While DWR treatments can wear off over time, they are a valuable addition to the waterproofing arsenal and can be reapplied as needed.
