Compatible with models such as 6YM-315-A L, 3ZM-315-A, 4YM-315-A, 9SR-317 N, and K5K-950H, this seal ensures optimal performance under high-pressure and variable load conditions. Manufactured from high-grade elastomeric materials, the 218-3520 seal offers superior resistance to wear, heat, and hydraulic fluid degradation, maintaining a reliable seal in harsh operating environments.<\/p>\n<p>Technically, the 218-3520 Seal-O-Ring features precise dimensional tolerances tailored to fit critical hydraulic and drivetrain interfaces, preventing fluid leakage and contamination ingress. Its robust metallurgy and advanced compound formulation provide excellent elasticity and compression set resistance, which are essential for maintaining seal integrity over extended service intervals. This OEM-quality part supports efficient machine operation by minimizing downtime and reducing maintenance costs, making it an indispensable component for maintaining Caterpillar excavators and wheel loaders at peak performance.<\/p>\n<p>\ud83d\udd17 For genuine Caterpillar 218-3520 Seal-O-Ring and detailed specifications, visit <a href=\"https:\/\/allparts.expert\/es\/parts\/mining\/caterpillar-218-3520-seal-o-ring-2183520\/\">Caterpillar 218-3520 Seal-O-Ring at AllParts.Expert<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>6YM-315-A L Excavator<br \/>\n3ZM-315-A Excavator<br \/>\n4YM-315-A Excavator<br \/>\n9SR-317 N Excavator<br \/>\n9SR-317-A N Excavator<br \/>\n4MM-317-A Excavator<br \/>\n6XM-315 Excavator<br \/>\n3KG-E650 Excavator<br \/>\nK5K-950H Wheel-type Loader<br \/>\nK6K-962H Wheel-type Loader<\/p>","protected":false},"featured_media":19893,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"_joinchat":[]},"product_brand":[36],"machine-type":[52],"model_no":[40226,7045,7046,7048,7049,7050,775,27683,105319],"product_cat":[144],"product_tag":[115072,112350,115075,115067,115076,115077,115074,107052,114730,115073,23395,115071,115079,40198,115068,115078,22635],"class_list":{"0":"post-20044","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-caterpillar","7":"machine-type-excavator","8":"model_no-40226","9":"model_no-315-a","10":"model_no-315-a-l","11":"model_no-317-n","12":"model_no-317-a","13":"model_no-317-a-n","14":"model_no-950h","15":"model_no-962h","16":"model_no-e650","17":"product_cat-mining","18":"product_tag-2183520-o-ring","19":"product_tag-3kg-e650-excavator-seal","20":"product_tag-3zm-315-a-seal","21":"product_tag-4mm-317-a-excavator-seal","22":"product_tag-4ym-315-a-o-ring","23":"product_tag-6xm-315-excavator-parts","24":"product_tag-6ym-315-a-excavator-parts","25":"product_tag-9sr-317-n-excavator-seal","26":"product_tag-9sr-317-a-n-o-ring","27":"product_tag-cat-218-3520-seal","28":"product_tag-cat-wheel-loader-spare-parts","29":"product_tag-caterpillar-218-3520-seal","30":"product_tag-caterpillar-excavator-seal-parts","31":"product_tag-construction-machinery-o-ring","32":"product_tag-k5k-950h-wheel-loader-seal","33":"product_tag-k6k-962h-wheel-loader-o-ring","34":"product_tag-mining-equipment-seals","36":"first","37":"instock","38":"shipping-taxable","39":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product\/20044","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/comments?post=20044"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/media\/19893"}],"wp:attachment":[{"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/media?parent=20044"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product_brand?post=20044"},{"taxonomy":"machine-type","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/machine-type?post=20044"},{"taxonomy":"model_no","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/model_no?post=20044"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product_cat?post=20044"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product_tag?post=20044"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
