Frequently Asked Questions
Open your model’s Illustrated Parts List and check the fluid-section bill of materials. If the seal stack line item shows 166165, you can use it. If not listed, contact support with your model and serial code.
PTFE offers excellent chemical resistance and low friction, making it ideal for many solvent or abrasive coatings. Some pumps use mixed stacks (e.g., leather + PTFE) to balance sealing and lubrication; follow the stack specified in your IPL.
Visible weeping at the throat, difficulty holding pressure, pulsation, or rapid pressure drop after priming. If these occur, inspect the rod and replace the packing stack as part of a fluid-section service.
