It supports hydraulic cylinder resealing during repair work when worn sealing elements may contribute to oil leakage, pressure loss, or reduced operating stability. Correct fitment depends on the specific cylinder group, as one machine may use different seal kits across its hydraulic functions. Please verify the machine serial number, cylinder group, existing part reference, and removed-seal profile before ordering. Ruijueparts supports 100,000+ part-number reference checks, multi-SKU enquiries, selected older-equipment sourcing, and neutral or customer-specified packaging for B2B orders.\u003c\/span\u003e\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%;\"\u003e526-1039\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\"\u003e426, 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 426 and 426 F2 backhoe loader hydraulic cylinder service.
