Product Overview

The Graco 248207 Piston Rod Repair Kit is the drive-side rod for the fluid section in larger Graco airless pumps. On each stroke, the rod transfers motion from the drive to the piston to draw material in and pressurize it for delivery to the hose and gun. Replacing a worn or scored rod restores sealing surface integrity and helps maintain pressure consistency, spray pattern quality, and pump longevity.

After installation, prime and pressure-test with clean solvent/water per material type before spraying.

Frequently Asked Questions

No. It’s intended for larger frames like Ultra Max II 1095/1595. Always match the part number to your exact model & pump revision in the official parts list.

It’s strongly recommended. Worn packings can damage a new rod and lead to leaks. Inspect and replace packings and the cylinder/sleeve if wear is present.

Some catalogs list 240-517 as a legacy reference for the same application. Use your sprayer’s illustrated parts breakdown to confirm the current, correct number.

Chronic packing leaks, pressure fluctuations, poor prime/hold, and visible scoring or discoloration on the rod. These often persist even after new packings if the rod is worn.

Always follow the torque specs and sealant/lube guidance in the service manual for your exact sprayer model. Incorrect torque can cause leaks or premature wear.
