Function of the Packing Kit

The packing kit helps:

• Seal around the ceramic plungers
• Maintain proper operating pressure
• Prevent internal water bypass
• Reduce external water leakage
• Improve pump efficiency
• Extend pump service life

Replacing worn packing and water seals helps restore pressure washer performance while protecting internal pump components from unnecessary wear.

Common Signs Replacement Is Needed

Replace the packing kit if you notice:

• Water leaking from the pump manifold
• Reduced operating pressure
• Decreased water flow
• Worn or damaged packings
• Pump rebuild or scheduled preventive maintenance
• Loss of cleaning performance

Replacing worn seals promptly helps prevent damage to ceramic plungers, manifolds, and other critical pump components.

Installation & Service Notes

• Shut down the pressure washer and relieve all system pressure.
• Remove the pump manifold according to the manufacturer's service procedures.
• Carefully remove the worn packing and sealing components.
• Clean all sealing surfaces thoroughly.
• Inspect ceramic plungers, water seals, and the manifold for wear or damage.
• Install the new OEM packing components in the correct orientation.
• Reassemble the pump and verify proper pressure and leak-free operation.

Important: Inspect ceramic plungers, O-rings, check valves, and additional sealing components during service. Replacing related wear items at the same time helps maximize pump reliability and service life.

Maintenance Recommendations

• Inspect packing and sealing components during routine pump maintenance.
• Replace worn seals at the first signs of leakage or pressure loss.
• Use clean, filtered inlet water to minimize seal wear.
• Never operate the pump without an adequate water supply.
• Use only genuine OEM AR replacement parts to maintain optimum pump performance, reliability, and long service life.
