Graco 595PC Hi-Boy Pump parts (17C487)

Stay Job-Ready with Long-Life Graco 595PC Hi-Boy Pump Parts (17C487) Components

Graco 595PC Hi-Boy is the “big-little” workhorse of small-commercial painting—lighter than a 695, yet strong enough to swing a 0.023″ tip at 3 300 psi. All that flow comes from a 17C487 Endurance™ Chromex pump lower. When that lower quits, productivity follows. Skip clone metal and order the serialized, factory-pressure-tested components listed below—graco bolts, seats, packings—each stamped to Graco specifications. Whether you service a single home-shop sprayer or a 12-rig fleet, our site warehouse is stocked up just for you.

Why Choose Genuine Graco 595PC Pump Parts?

• Chromex-Plated Rod 64 Rc — doubles wear life versus painted or spray-arc steel rods.
• V-Max Blue™ Hybrid Packings — UHMW/Leather stack seals under frost-line mornings and 110 °F attics.
• Carbide MaxLife™ Seats — shrug off titanium-dioxide latex that pits stainless in 30 gallons.
• ProConnect™ Door — drop the pump in or out in <60 s; no bench vise, no busted schedule.
• SmartControl 1.0 Capacitance — OEM graco hoses report true pressure; clone hoses create false alarms.
• Factory Warranty backed by Graco.
