Frequently Asked Questions
Check your machine’s parts manual or the label on the displacement pump. If the bill of materials lists 165052 for the intake/inlet seal, it’s the correct replacement.
Loss of pressure, seepage around the intake housing, difficulty priming, or visible damage/flattening on the old O-ring are common indicators.
The seal is PTFE (Teflon), widely compatible with many coatings and solvents. Always confirm chemical compatibility with the fluid manufacturer before use.
