Why Choose Genuine Graco 290 PC Hi-Boy Parts?

• Chromex-Plated Piston Rods – 64 Rc hardness doubles life versus spray-painted steel, even on abrasive roof elastomeric.
• V-Max Blue™ Hybrid Packings – self-lubricating UHMW and leather stack seals down to 40 °F dawn starts and up to 110 °F summer attics.
• SmartControl 1.0 Firmware – OEM pressure sensor holds fan width ±1 % from 300 psi fine-finish to 3 300 psi block-filler; clones “hunt” and waste paint.
• Endurance™ Pump Warranty – 12-month coverage stays valid only with genuine Graco seals and seats.
• Exact Thread & Seal Chemistry – NPSM swivels and Viton® O-rings withstand hot solvent flushes without weeping at the pivot.
