Frequently Asked Questions

Check your displacement pump part number. If your pump is 223842 (commonly found on the 30:1 President), this packing applies. When in doubt, consult your model’s parts manual or contact support with your exact sprayer model and serial.

Install vee packings in the correct orientation as shown in the pump manual, lubricate per spec, and tighten the packing nut to the recommended torque. After reassembly, prime the unit and verify there is no leakage at the rod.

Replace when you notice persistent drips at the throat, reduced pressure, rough pump stroke, or after a major abrasive/solvent-heavy job. Regular inspection during maintenance helps prevent downtime.

PTFE offers broad chemical resistance and low friction, making it suitable for many solvent-borne and waterborne coatings. Verify chemical compatibility with your specific materials before use.
