Frequently Asked Questions
Match the lower pump part number on your unit. If it’s 19Y298 or 19B732, and your sprayer is an Ultra Max II 650 PC Pro or Ultimate MX II 650, the 19Y269 Sleeve is the corresponding OEM sleeve.
It’s strongly recommended. A fresh sleeve with worn packings won’t restore pressure or prime reliably. Pair the sleeve with the correct V-Max Blue packing kit for your lower pump.
No. The 19Y269 is specific to 650-series lowers. Other sizes (e.g., 495/595/695/795/1095) use different sleeves and lowers. Always verify by lower pump part number.
Clean the lower thoroughly, inspect the piston rod for scoring, lube new packings per Graco specs, and torque fasteners evenly. Prime with compatible fluid and check for leaks before spraying.
Yes — the Graco 19Y269 Sleeve is an OEM replacement component designed for 650-series Endurance lowers. Authentic parts ensure proper fit and service life.
