Graco 248991 Pump Cylinder Sleeve brings exceptional durability to your maintenance arsenal, engineered for seamless integration with GH 230 and GH 300 models. Ideal for contractors and DIY enthusiasts, this sleeve enhances flow consistency in any airless sprayer, ensuring smooth operation and uniform application. Pair with your graco spray equipment to achieve optimal performance, backed by high-pressure filtration to maintain fluid purity and reduce downtime. With precision engineering, each sleeve offers corrosion resistance and extended service life under continuous cycles.
Designed to restore pump integrity, this cylinder sleeve is compatible with a range of professional coatings, delivering reliable pressure control when matched with your graco paint machines. Easy to install and maintain, it ensures top-tier productivity in demanding applications while protecting critical components from wear and corrosion. Ideal for heavy-duty environments, it supports even the toughest professional applications.
Pressure dips, motor surges and tell-tale stripes in the finish almost always trace back to a scored cylinder sleeve. Swapping the entire pump costs both money and precious uptime, but installing the OEM Graco 248991 Pump Cylinder Sleeve restores the heart of your Graco airless sprayer in a single service window. Precision-ground and hardened to Graco’s exacting tolerances, this sleeve eliminates internal blow-by, stabilises hydraulic pulses and protects the downstream Graco spray gun parts that create your signature finish.
• Precision-honed bore for micro-scale tolerance control
• 3,300 psi (227 bar) pressure rating for heavy-duty coatings
• Supports fluid temps to 85 °C without loss of concentricity
• Cryogenic stress-relief extends fatigue life past 10,000 cycles
• Drop-in fit—no shims, spacers or finish machining required
The 248991 sleeve drops straight into the GH 230 and GH 300 displacement pumps no adapters needed. Always double-check your owner’s manual, but if your data plate lists either model, this is the factory sleeve your pump was born with.
A scored sleeve forces operators to crank the regulator, hammering packings and starving the gun of consistent flow. Replacing it with an OEM part smooths pressure curves, extending the life of Graco spray gun accessories such as RAC X tips, clean-shot valves and whip hoses. You’ll see sharper fan patterns, fewer tip clogs and better transfer efficiency results that keep clients coming back.
1) Flush until clear at the end of every shift
2) store with Pump Armor in the fluid section
3) wipe the exposed rod with TSL before first spray. Combined with the precision-honed sleeve, these habits have been shown to extend mean time between repairs from 250 to over 400 operating hours.
Q: Will this sleeve fit my GH 200?
A: No—the GH 200 uses a shorter cylinder. For that model, order Graco 248980 instead.
Q: Do I need new packings?
A: If the old sleeve was badly scored, chances are the V-packs are damaged. Replace them with the 287813 kit to lock in the performance boost.
