Manufactured from high-grade elastomeric materials, this O-ring provides exceptional resistance to heat, pressure, and chemical exposure, ensuring reliable sealing performance under extreme load conditions. Its exact dimensions and compatibility with a wide range of Caterpillar equipment make it an essential part for maintaining drivetrain integrity and preventing fluid leaks.<\/p>\n<p>Engineered for optimal performance, the 529-2381 Seal-O-Ring features superior elasticity and compression set resistance, critical for sustaining long-term sealing efficiency in hydraulic systems and engine components. Its metallurgy and material composition are tailored to withstand the harsh operating environments typical of wheel-type loaders (e.g., 7HR-992G, AZX-992G) and road reclaimers (e.g., GMP-RM800, BT8-RM600). By maintaining tight seals, this O-ring helps reduce downtime and maintenance costs, contributing to improved machine reliability and operational productivity. OEM-grade quality guarantees compatibility and longevity, making it a trusted choice for heavy equipment maintenance professionals.<\/p>\n<p>\ud83d\udd17 For more detailed specifications and to purchase the Caterpillar 529-2381 Seal-O-Ring, visit the official product page at <a href=\"https:\/\/allparts.expert\/es\/parts\/mining\/caterpillar-529-2381-seal-o-ring-5292381\/\">Caterpillar 529-2381 Seal-O-Ring on AllParts Expert<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"<p>CEY-G3516B Engine &#8211; Generator Set<br \/>\nCFD-PMG3516 Engine &#8211; Generator Set<br \/>\n4HZ-5230B Excavator<br \/>\n4CS-5130B Excavator<br \/>\n7LL-5230 Excavator<br \/>\n5ZL-5130 Excavator<br \/>\nGMP-RM800 Road Reclaimer<br \/>\nBT8-RM600 Road Reclaimer<br \/>\nNAF-RM600 Road Reclaimer<br \/>\nKFS-RM800 Road Reclaimer<br \/>\nTPW-RM800 Road Reclaimer<br \/>\nAAF-D11R Track-type Tractor<br \/>\nMDG-D11T Track-type Tractor<br \/>\nTPB-D11T Track-type Tractor<br \/>\n9XR-D11R Track-type Tractor<br \/>\nJNS-D11T Track-type Tractor<br \/>\nKSN-D11 Track-type Tractor<br \/>\nTKN-D11 Track-type Tractor<br \/>\n7HR-992G Wheel-type Loader<br \/>\nAZX-992G Wheel-type Loader<br \/>\nH4C-992K Wheel-type Loader<br \/>\nADZ-992G Wheel-type Loader<br \/>\nKK4-992K Wheel-type Loader<br \/>\n880-992K Wheel-type Loader<br \/>\nKK2-992K Wheel-type Loader<br \/>\nRM2-992K Wheel-type Loader<br \/>\nRM5-992K Wheel-type Loader<br \/>\nZMX-992K Wheel-type Loader<br \/>\nW9B-H160E S Work Tool<br \/>\nHWY-H160S Work Tool<br \/>\nHK7-H160E Work Tool<br \/>\n4TW-S130 Work Tool<br \/>\nM6L-RM600 Road Reclaimer<br \/>\nR6H-RM600 Road Reclaimer<br \/>\nL8L-RM800 Road Reclaimer<br \/>\nE8H-RM800 Road Reclaimer<\/p>","protected":false},"featured_media":26067,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"_joinchat":[]},"product_brand":[36],"machine-type":[28676],"model_no":[7208,4984,4437,5801,1659,1658,2669,1824,45,97,49123,49121,49122,19737,39337,39336,83159],"product_cat":[144],"product_tag":[57680,167488,167471,167478,135081,167485,167482,167469,167467,167473,39030,167474,167476,167483,167480,167486],"class_list":{"0":"post-27616","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-caterpillar","7":"machine-type-engine-generator-set","8":"model_no-7208","9":"model_no-5130b","10":"model_no-4437","11":"model_no-5230b","12":"model_no-992g","13":"model_no-992k","14":"model_no-d11","15":"model_no-d11r","16":"model_no-d11t","17":"model_no-g3516b","18":"model_no-h160e","19":"model_no-h160e-s","20":"model_no-h160s","21":"model_no-pmg3516","22":"model_no-rm600","23":"model_no-rm800","24":"model_no-s130","25":"product_cat-mining","26":"product_tag-4hz-5230b-excavator-parts","27":"product_tag-529-2381-heavy-equipment-spare-part","28":"product_tag-529-2381-o-ring-replacement","29":"product_tag-5zl-5130-excavator-o-ring","30":"product_tag-7ll-5230-excavator-seal","31":"product_tag-992k-wheel-type-loader-seal","32":"product_tag-bt8-rm600-road-reclaimer-parts","33":"product_tag-cat-5292381-seal-o-ring","34":"product_tag-caterpillar-529-2381","35":"product_tag-caterpillar-engine-seal-529-2381","36":"product_tag-caterpillar-mining-equipment-seals","37":"product_tag-cey-g3516b-generator-seal","38":"product_tag-cfd-pmg3516-seal-o-ring","39":"product_tag-d11t-track-type-tractor-seal","40":"product_tag-gmp-rm800-road-reclaimer-seal","41":"product_tag-w9b-h160e-work-tool-seal","43":"first","44":"instock","45":"shipping-taxable","46":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product\/27616","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=27616"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/media\/26067"}],"wp:attachment":[{"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/media?parent=27616"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product_brand?post=27616"},{"taxonomy":"machine-type","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/machine-type?post=27616"},{"taxonomy":"model_no","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/model_no?post=27616"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product_cat?post=27616"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/allparts.expert\/es\/wp-json\/wp\/v2\/product_tag?post=27616"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
