This compact, standalone seal is designed for Cat equipment and replacements that specify a 18.77 mm ID O-ring, and it is listed in Caterpillar’s official CATCorp catalog as 5P-9757, confirming its identity as a Cat sealing component. Some third-party listings describe 5P9757 specifically as an O-ring seal used with governor piston assemblies, reflecting Caterpillar’s use of this size in hydraulic and mechanical interfaces that require a precise, leak-tight seal. As a Cat-brand part, it is intended to meet Caterpillar service specifications for sealing interfaces where an 18.77 mm ID O-ring is required, so when selecting a replacement verify the groove size and mating surface in the target Cat assembly to ensure proper fit and performance. The 18.77 mm inner diameter is a precise dimension that defines the seal's compatibility with the corresponding Cat groove and sealing surface, contributing to reliable operation in Cat hydraulic and engine interfaces.\u003c\/p\u003e\u003c\/div\u003e","brand":"Caterpillar","offers":[{"title":"New Surplus No Box","offer_id":51677845684526,"sku":null,"price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_87e05fbe-ba85-46e3-bfed-7f403ef80cca.jpg?v=1769568323","url":"https:\/\/plgautomation.com\/products\/caterpillar-5p-9757-seal-for-caterpillar-5p-9757","provider":"PLG Automation ","version":"1.0","type":"link"}
