In addition to their durability, combi oil seals are also designed to provide a tight and reliable seal. This is crucial for preventing the leakage of oil or other liquids from the machinery. A tight seal ensures that the machinery operates efficiently and minimizes the risk of damage or malfunction.

Oil seals are typically made of rubber or synthetic materials that are resistant to oil, heat, and pressure. They are designed to withstand the harsh conditions within an engine or machinery, such as high temperatures and varying levels of pressure. The seal is usually placed in a housing or a groove in order to effectively seal the gap between two moving parts.

One of the most critical features to look for in a sewing machine for both fabric and leather is stitch control. The ability to adjust the stitch length and type is vital when switching between materials. For instance, when sewing leather, a longer stitch length (usually between 3-5mm) helps reduce the chances of puncturing the material too many times, which can lead to tearing. In contrast, for lightweight fabrics, a shorter stitch length provides greater control and a more refined finish.
