Frequently Asked Questions
PTFE resists common coatings/solvents, has low friction for smoother piston movement, and holds shape under pressure—key for maintaining seal integrity in high-pressure pumps.
Match your model and pump variant against the official Graco parts manual. Look under the pump/packing stack diagram and verify the reference for part 164622 before purchase.
Replace during a packing service or if you observe pressure loss, poor atomization, or leakage around the packing/cylinder. Always inspect related packings and rings concurrently.
