Made from a steel core coated with Nitrile Rubber (NBR), this end cap provides excellent sealing and mechanical strength while protecting internal components such as bearings from oil, dust, and environmental contaminants. Ideal for a wide range of industrial, mechanical, and hydraulic applications. \u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eBrand : AVX Seals\u003c\/li\u003e\n\u003cli\u003eItem Sku : EC40x5\u003c\/li\u003e\n\u003cli\u003eType : EC 40x5 mm\u003c\/li\u003e\n\u003cli\u003eOuter : 40mm\u003c\/li\u003e\n\u003cli\u003eWidth : 5mm\u003c\/li\u003e\n\u003cli\u003eSize : 40mm x 5mm\u003c\/li\u003e\n\u003cli\u003eSeal Material : Nitrile Butadiene Rubber\u003c\/li\u003e\n\u003cli\u003eTemperature Range : -40 to 248 F\u003c\/li\u003e\n\u003cli\u003eSeal Type: Static (for non-rotating, non-passing shafts)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 class=\"\" data-start=\"1513\" data-end=\"1536\"\u003e\u003cstrong data-start=\"1519\" data-end=\"1536\"\u003eApplications: Nitrile Rubber End Cap\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul data-start=\"1537\" data-end=\"1834\"\u003e\n\u003cli class=\"\" data-start=\"1537\" data-end=\"1585\"\u003e\n\u003cp class=\"\" data-start=\"1539\" data-end=\"1585\"\u003e\u003cstrong data-start=\"1539\" data-end=\"1566\"\u003eElectric motor housings\u003c\/strong\u003e (non-drive ends)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"\" data-start=\"1586\" data-end=\"1627\"\u003e\n\u003cp class=\"\" data-start=\"1588\" data-end=\"1627\"\u003e\u003cstrong data-start=\"1588\" data-end=\"1601\"\u003eGearboxes\u003c\/strong\u003e with unused shaft bores\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"\" data-start=\"1628\" data-end=\"1659\"\u003e\n\u003cp class=\"\" data-start=\"1630\" data-end=\"1659\"\u003e\u003cstrong data-start=\"1630\" data-end=\"1657\"\u003ePump and valve housings\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"\" data-start=\"1660\" data-end=\"1699\"\u003e\n\u003cp class=\"\" data-start=\"1662\" data-end=\"1699\"\u003e\u003cstrong data-start=\"1662\" data-end=\"1697\"\u003eHydraulic and pneumatic systems\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli class=\"\" data-start=\"1700\" data-end=\"1731\"\u003e\n\u003cp class=\"\" data-start=\"1702\" data-end=\"1731\"\u003e\u003cstrong data-start=\"1702\" data-end=\"1729\"\u003eSealed bearing chambers\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 class=\"\" data-start=\"1841\" data-end=\"1883\"\u003e❓ \u003cstrong data-start=\"1846\" data-end=\"1883\"\u003eFrequently Asked Questions (FAQs)\u003c\/strong\u003e\n\u003c\/h2\u003e\n\u003ch3 class=\"\" data-start=\"1885\" data-end=\"1933\"\u003e✅ \u003cstrong data-start=\"1891\" data-end=\"1931\"\u003eQ1: What does the Nitrile Rubber End Cap (EC40x5) do?\u003c\/strong\u003e\n\u003c\/h3\u003e\n\u003cp class=\"\" data-start=\"1934\" data-end=\"2123\"\u003e\u003cstrong data-start=\"1934\" data-end=\"1941\"\u003eA1:\u003c\/strong\u003e It \u003cstrong data-start=\"1945\" data-end=\"1976\"\u003eseals a static housing bore\u003c\/strong\u003e where a shaft does \u003cstrong data-start=\"1996\" data-end=\"2012\"\u003enot protrude\u003c\/strong\u003e, preventing contamination and protecting internal parts such as \u003cstrong data-start=\"2077\" data-end=\"2089\"\u003ebearings\u003c\/strong\u003e from \u003cstrong data-start=\"2095\" data-end=\"2122\"\u003edirt, oil, and moisture\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch3 class=\"\" data-start=\"2130\" data-end=\"2182\"\u003e✅ \u003cstrong data-start=\"2136\" data-end=\"2180\"\u003eQ2: Can this be used on rotating shafts?\u003c\/strong\u003e\n\u003c\/h3\u003e\n\u003cp class=\"\" style=\"text-align: left;\" data-start=\"2183\" data-end=\"2347\"\u003e\u003cstrong data-start=\"2183\" data-end=\"2190\"\u003eA2:\u003c\/strong\u003e No. The Nitrile Rubber End Cap (EC40x5) is a \u003cstrong data-start=\"2211\" data-end=\"2239\"\u003estatic sealing component\u003c\/strong\u003e and is \u003cstrong data-start=\"2247\" data-end=\"2289\"\u003enot suitable for rotating applications\u003c\/strong\u003e.
