Green compressor packing
This design, used in a packing case assembly, consists of a five ring set; male radial ring, and a tangent cut ring as shown. The wedge packing set is installed facing the point of highest pressure. It is used to seal the purge connection and also to prevent leakage of gas along the rod when the compressor is shut down under the load.

    Material Description
    		AVA47 provides exceptional long life in those applications where there are hydrocarbons or liquids flowing intermittently in the gas. Standard carbon filled PTFE rings depend on riding over a coating of PTFE on the rod or the cylinder to provide minimal ring wear. In applications where solids or liquids are present and tend to remove the coating provided by standard carbon filled, AVA47 is the material of choice. By adding anti-friction materials, excellent ring life is achieved along with eliminating wear on the piston rod, piston or cylinder wall.
    Recommended Applications: Lubricated Service, Wet CO2, Natural Gas, Vinyl Chloride

    AVA47 Application Profile.
    AAVOLYN's AVA47 PTFE blend profiled by E.I. duPont.

    AVA47 filled PTFE - This proprietary material is ideally suited for lubricated and mini-lube service, especially where solids and liquids are prevalent in the gas stream. Piston rings, rider rings and rod packing manufactured from AVA47 have outperformed the standard material available in the Natural Gas Market today.
