Since PTFE is a self lubricating material non-lubricated bearings, seals, piston rings, rider rings, piston rod   packing, chevron rings, O rings etc., are in great demand amongst design engineers.

  The use of fillers with PTFE changes certain properties and permits the material to be tailored to a wide variety   of mechanical applications. In general, use of additives increases stiffness, hardness, compressive strength and   resistance to deformation under load.We manufacture these rings for all types of non lubricated compressors.
