This is the bore the piston travels in, and its surface is what every packing in the wet end seals against.\u003c\/p\u003e\n\u003cp\u003eA cylinder outlasts many sets of packings, but once the bore is scored no new packing set will hold pressure for long. Shops rebuilding a high-hour Dura-Flo 750 inspect the bore before ordering seals, since fitting fresh packings into a worn cylinder is the most common reason a rebuild fails early. The 180cc lower is rated to 6800 psi, so bore condition directly limits what the pump can hold.\u003c\/p\u003e\n\u003cp\u003eCommon reasons for replacement:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eScoring, grooves or pitting in the bore, seen or felt during a rebuild\u003c\/li\u003e\n\u003cli\u003eFresh packings that fail again shortly after a rebuild\u003c\/li\u003e\n\u003cli\u003ePressure that will not hold on the downstroke even with new piston packings\u003c\/li\u003e\n\u003cli\u003eMaterial bypassing the piston, showing up as reduced output at an unchanged cycle rate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eManufactured to OEM-equivalent dimensions for proper fit and performance.\u003c\/p\u003e\n\u003cp class=\"p2\"\u003eComparable to GRACO® 189-857\u003c\/p\u003e\n\u003cdiv align=\"left\"\u003e\u003cb\u003eNOTES:\u003c\/b\u003e\u003c\/div\u003e\n\u003cdiv\u003eGRACO®, PerfomAA™, Merkur™  and Reverse-A-Clean® (RAC) Tip are registered trademarks of GRACO®, and the same company may claim unregistered trademark rights in other words.
