hydraulic gear pump seals
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.
what is the function of oil seal

According to the American Cancer Society, PAHs form when fat and juices from meat grilled directly over a heated surface or open fire drip onto the charcoal. Charcoal burns hotter than gas and it creates a lot of smoke. Even though many people like the smoke flavor a charcoal grill provides, smoke is not a good thing when accompanied by PAHs, which can get deposited on the food you are cooking. PAHs can also form directly on the food as it is charred. PAHs can be found in other smoked foods, as well as in cigarette smoke and car exhaust fumes.
