Frequently Asked Questions

Yes—17K162 is the OEM repair/packing kit for the 16X420 Endurance Pump. If your sprayer uses that pump lower, this is the correct kit (verify with your parts manual for year/variant specifics).

Commonly: Ultra Max II 1095/1595 (ProContractor/IronMan), GMAX II 5900 (ProContractor/IronMan), and selected Ultimate MX II 1095/1595 models that specify the 16X420 pump lower.

Loss of prime, visible paint leakage from the pump, inability to reach/hold set pressure, frequent pressure fluctuations, or excessive cycling are typical signs the pump packings are worn.

Flush after use, strain coatings, keep filters/tips matched to material, avoid dry-running, and store with pump protectant when idle. These steps help maximize the service life of the new packings.

No. Packing kits are pump-specific. Use 17K162 only for pump lowers designed for it—primarily the 16X420. If your pump number differs, consult the parts manual for the correct kit.
