- Contractor PC Gun or graco magnum x7 replacement spray gun—25 % lighter trigger pull reduces hand strain on 10-hour shifts.
- BlueMax II Hose (50 & 100 ft)—rated 3300 psi; mates to graco spray tips up to 0.027″ without starving the pattern.

Pro Tips for Zero-Downtime Maintenance
- Log Pump Hours — repack every 500 hours; tag each sprayer’s handle with next-service stickers to enforce discipline.
- Flush Daily with warm water or Pump Armor; rust in the manifold starves your graco suction hose and burns packings.
- Wet-Cup Discipline—top off TSL once per shift; a dry cup scores rods and halves seal life.

- Carry a Spare Lower—the 16Y598 pays for itself by avoiding a single half-day shutdown.
Frequently Asked Questions
Will 16Y598 fit a 2014 Ultra Max II 795?
Yes—bolt pattern is unchanged since 2013. If your rig still uses a first-gen ProConnect cradle, add retrofit kit 17C721 for perfect alignment.
Can I push roof coatings through a 0.031″ tip?
The 2 hp motor on the 795 sustains 3000 psi at a 0.031″ RAC X SwitchTip on 150 ft of hose—ideal for elastomerics.
How does Chromex compare to aftermarket steel rods?
Chromex rods show 0.0003″ wear after 120 hours vs. 0.0015″ on mild steel—five-fold longevity.
Do you stock parts for our fleet of graco 7900 line stripers?
Absolutely. Tip guards, filters, piston seals, and belt kits sit next to every 16Y598 on our shelf for one-ticket checkout.
