I have the 30-9 Parker single puck. Needing to replace the O-Ring. I have read in the parts manual for the 30-9 that the 101-02300 (23mm) is the replacement O-Ring but not sure if a similar Nitrile or Viton 23MM will work. I pulled a 23MM from the Parker assortment of O-Rings I have at home and that lasted about 60 hours. Might be the 8606 Hydraulic fluid working on the regular rubber. When I picked the O-Ring out of the puck it was square like it might not have been the right composition or it would have retained its shape. Some swear by Viton O-Rings. Others say they don't do well in cold. The replacement ring is $20 per O-Ring at Spruce for the original part number. Anyone that has gone down this path with the Parker 23mm O-Ring?
