The official reference contains seven sealing-related components, including a wiper seal, O-ring, and expander ring, so this is more than a single replacement oil seal. Match the cylinder group and removed components before purchase. Ruijueparts can cross-check mixed parts lists, review photos for selected older equipment, and provide neutral or customer-specified packaging for B2B orders.\u003c\/p\u003e\n\u003cbr\u003e\u003c!--TgQPHd||[]--\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"Fsg96\"\u003e\u003c!--TgQPHd||[]--\u003e\u003c\/div\u003e\n\u003ch2 id=\"s0-2-1-25-5-20-1-101[1]-2-3-7[0]-4[0]-3[0]-11[1]-1-5-title\" class=\"section-title__title\"\u003e\u003cspan class=\"ux-layout-section-module-evo__title\"\u003e\u003cspan class=\"ux-textspans\"\u003eItem specifics\u003c\/span\u003e\u003c\/span\u003e\u003c\/h2\u003e\n\u003ctable width=\"100%\" style=\"width: 100.088%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.6518%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003ePart Number:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd class=\"et2\" height=\"17\" width=\"76\" style=\"height: 17pt; width: 65.9112%;\"\u003e512-0512\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.6518%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eFits Models:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9112%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e424, 426, 426 F2\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.6518%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eBrand:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9112%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eCATERPILLAR replacement\u003c\/span\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.6518%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003eType:\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9112%;\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cmeta charset=\"utf-8\"\u003eHydaulic Cylinder Seal Kit \/ Aftermarket Replacement Parts\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 33.6518%;\"\u003e\u003cstrong\u003e\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eApplication:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.9112%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eFor Caterpillar-compatible 424, 426, and 426 F2 backhoe loader hydraulic cylinder repair.
