Frequently Asked Questions
Check the lower/displacement model on your unit’s data plate or in the parts manual. If it lists Dura-Flo 1800 (430 cc) lowers such as L430CS or L430SS, the 184461 is the correct cylinder family. For rigs, cross-reference the lower model installed in the frame.
L430CS refers to a Carbon-Steel lower; L430SS is a Stainless-Steel lower. Match the cylinder material to the lower type specified by your manual or serial tag.
DF1800 (430 cc) systems are typically around ~4500 psi fluid working pressure, but the exact rating depends on your air/hydraulic motor and system configuration. Always verify the rating for your exact model in the Graco manual.
Excess bypass/leak-down, poor priming, pressure loss, or visible scoring wear inside the lower. Inspect during a packing rebuild; if out of spec or damaged, replace with 184461.
