Rings & Compressor Components

Sealing Rings

Carbon sealing rings are used as the wear face of most mechanical seals for the sealing of fluids in all sealing of fluids in all industries. 

Applications are:

  • Process pumps 
  • Rotary steam joints 
  • Seals for agitators and autoclaves 
  • Chemical pumps 
  • Cold and warm water pumps
  • Corrosive liquid pumps. 

Carbon is well suited to be used as a sealing ring due to having the following properties:

  • Very good chemical resistance 
  • Good thermal conductivity 
  • High wear resistance 
  • Good corrosion resistance 
  • Dry running properties
  • Good frictional properties 
  • Outstanding resistance thermal shock 
  • Low thermal expansion 

Due to the need for sealing rings to be impervious the carbon material is impregnated with either resin or various metals. Morgan Industrial Carbon should be contacted to ensure the correct grade is used for the application. Seal faces can be supplied unlapped or if required lapped to three helium light bands of flatness. 

Carbon seal faces are compatible with a wide range of metallic and ceramic counterfaces including silicon carbide and tungsten carbide. 

 Compressor Components

For Non-Lubrication or Oil-Free Compressors 

Various makes of Non- Lubricated Compressors utilise Piston/Bearing rings and Gland Packings in their mechanics, made from self-lubricating materials such as carbon. Various grades of carbon are available to suit individual applications and great care in selecting the right grade of material is taken. Morgan Industrial Carbon can also supply Oil Scraper Rings (Wiper Rings) in bronze, white metal materials as requested for the sealing of oil from the compressor crankcase area.


Area of service for non-lubricated compressors include:

  • Oxygen plants where oil use would present a fire and explosion hazard. 
  • Instrument air compressors to prevent oil from clogging air operated control systems 
  • Process air for food industries to avoid oil contamination of food 
  • Breweries for the compression of CO2 and process air 
  • Petroleum refining and processing industries for handling of gases and non-lubricating fluids 
  • Chemical industries to prevent oil contamination of end products 
  • Medical oxygen for hospital use.
