Upper Packing Kit for Airless Sprayer & RentSpray Models

The 704-564 Upper Packing Kit provides all necessary seals to rebuild the upper section of the fluid pump on compatible Airless Sprayer and RentSpray units. The kit includes the main packing, backup ring, O‑rings, and retaining hardware needed to restore a tight seal between the piston rod and pump cylinder.

A worn upper packing can cause paint to leak from the pump’s upper area, loss of prime, erratic pressure, or excessive fluid bypass. Rebuilding with this genuine kit restores pump efficiency, reduces downtime, and prevents damage to the piston rod and cylinder.

Service Guidance: Before installation, inspect the piston rod for scoring or wear. Clean the packing cavity thoroughly and lubricate new components with compatible pump oil. Tighten retaining hardware to specification.

Frequently Asked Questions

The kit contains the upper packing (U‑cup), a backup ring, two O‑rings (large and small), and a retaining washer. All components are required for a complete upper seal rebuild.

Common signs: paint leaking from the top of the pump, difficulty priming, pressure loss, or erratic spray pattern. The pump may also cycle continuously without building pressure.

It is designed for Airless Sprayer models 640 IX, 540IX, 440IX and RentSpray 650, 600. Always confirm with your parts diagram.

Basic hand tools (wrenches, screwdrivers) are usually sufficient. A packing installation tool can help seat the U‑cup without damage. Lubricate all seals with pump oil before assembly.
