Frequently Asked Questions

Signs include leakage around the throat/wet cup, pressure drop, pulsation, difficult priming, or a rough spray pattern. Inspect the rod for scoring; damaged rods will prematurely wear new packings.

Yes—those models are covered by this kit. For units outside this list, confirm by checking your pump’s parts breakdown and serial range.

Typically piston and throat packings, select O-rings, glands, and small hardware needed to reseal the pump section. Exact contents can vary slightly; refer to the insert that ships with the kit.

No specialty tools are usually required beyond standard hand tools. Follow the sprayer’s service manual for torque specs and packing nut adjustment. A clean bench and proper lube are essential.

Prime with compatible solvent or material, run at low pressure to verify sealing, then bring pressure up gradually. Keep the wet cup filled and re-check the packing nut after initial runtime.
