The Ultimate MX II 695 is the current-generation platform featuring improved pressure stability, faster priming cycles via the prime/drain valve system, and enhanced transducer integration. Both share the same pump displacement and PSI range, but MX II units have updated electronics and serviceability. Check your manual's model designation to order compatible parts.

Manufacturer guidance recommends packing inspection every 500–750 operating hours or annually, whichever comes first. Signs of wear include pressure fluctuation, fluid seepage around the pump rod, or reduced output. The 18B260 packing kit and 117559 O-ring sets are preventive maintenance items; early replacement avoids pump failure and downtime.

Partial compatibility exists for shared components (e.g., the 246386 suction hose kit fits 390/395/490/595/695 models), but pump assemblies, valve kits, and transducers are model-specific. Always cross-reference your sprayer's serial number and manual before ordering. Using mismatched parts risks pressure loss or seal failure.

Pressure loss typically stems from worn pump packing (seal leakage), failed pressure transducer calibration, or blocked suction lines. Check hose connections for leaks first, then inspect the pump rod for fluid weeping. If the transducer shows fluctuating readings, it may need replacement (part 243222). Worn packing requires the 18B260 kit and pump disassembly.

No. The prime/drain valve is a serviceable component; Graco 695 models use the 235014 and 239914 valve kits as bolt-on replacements. Failure symptoms include slow priming, stuck plungers, or inability to purge paint. These kits typically cost a fraction of pump replacement and restore full function within 30 minutes.
