Oil Seals & Gaskets are essential components of air compressors that prevent leaks and maintain the pressure of compressed air to ensuring their efficiency and longevity.
Oil Seals
Stop fluids and grease from leaking out of the clearance between a rotating shaft and a housing or gear box. Oil seals can also prevent dirt and other contaminants from entering the compressor.
- Purpose – Oil seals prevent the leakage of lubricating oil from the compressor. They are designed to keep oil contained within the engine or compressor housing while preventing dirt and contaminants from entering.
- Function – Typically made of rubber or synthetic materials, oil seals create a tight seal around rotating shafts. This minimizes friction and wear and it helps maintain optimal operating conditions by reducing the chances of oil loss.
Gaskets
Prevent air from leaking out of the compression chamber, keeping pressurized air contained within the system. Gaskets are used in various parts of an air compressor, such as the crankcase, intercooler and valve plate.
- Purpose – Gaskets are used to create a seal between two surfaces, such as between the compressor’s cylinder and the head. They help to prevent air or gas leaks and ensure proper compression.
- Function – Made from materials like rubber, cork, or composite materials, gaskets fill the gaps between mating surfaces. They compress when bolted together, forming a tight seal that withstands pressure and temperature changes.
Different types of packing materials are used in air compressors, including graphite, PTFE (Teflon), non-asbestos, aramid, and natural rubber. The type of packing material used depends on the compressor’s operating conditions, such as temperature, contaminants and gases or liquids handled.
Other benefits of oil seals and gaskets are essential for maintaining the efficiency, performance and reliability of air compressors to improved air quality, longer compressor life and smooth airflow. They help prevent leaks, protect internal components, and ensure that the compressor operates smoothly. Regular inspection and replacement of these components are vital for optimal compressor function.
