Installation & Care Tips

Confirm your sprayer’s model & pump number before disassembly.

After installation, prime with appropriate fluid and check for leaks at low pressure before spraying.

Frequently Asked Questions

Match your sprayer model and verify the pump assembly number. If your 650 uses pump 19B732 or 19Y298, this rod is correct. When in doubt, check your parts manual or the pump breakdown for your exact unit.

It’s strongly recommended. A new rod running through worn packings (or a scored sleeve) will not seal properly and can wear prematurely. Replace any damaged sleeve/cylinder at the same time for best performance and longevity.

Yes—listings identify 19Y268 as a Chromex rod for UltraMax II 650 PC Pro, providing enhanced wear resistance for pump longevity.

No. This rod is specific to the 650 platform. Other Ultra/Ultimate models use different pump assemblies and rods. Use the part number in your machine’s manual to avoid mismatches.

Look for scoring on the rod, packing leaks that reoccur quickly, pressure drop/pulsing, and inconsistent spray pattern. These point to rod and/or sleeve wear.
