The Type 320 radial oil scraper ring is designed to be used pinned in sets as a wiper
assembly. Its function is to wipe oil from the piston rod and prevent it from traveling into the
packing area. The 320 design is installed with the wiping edge toward the oil source to
provide maximum oil removal.
The AAVOLYN 320 design includes the unique tapered wiping edge, deep oil grove in the
bore and large oil ports to allow rapid removal of oil wiped from the rod. It is utilized in many
gas and process compressors depending on the design of the compressor manufacturer.
