This precision-sized elastomeric sealing ring provides reliable static and dynamic sealing to prevent lubricant leakage from gear cases, block moisture and debris ingress through tool body interfaces, and maintain proper internal pressure in pneumatic and hydraulic tool components. Manufactured to Milwaukee's exact material and dimensional specifications, this O-Ring ensures the correct elastomer compound, durometer, inside diameter, and cross-sectional diameter for its intended sealing groove. Replace this component whenever the existing O-Ring exhibits compression set, cracking, swelling, or physical damage to restore full tool sealing performance.\u003c\/p\u003e\n\n\u003cp class=\"h3\"\u003e\u003cb\u003eFeatures\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp class=\"h4\"\u003eGenuine Milwaukee OEM O-Ring with correct dimensions and elastomer for the specific tool application\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp class=\"h4\"\u003eRestores lubricant containment and debris\/moisture exclusion sealing function\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp class=\"h4\"\u003eCorrect material, diameter, and cross-section critical for effective sealing performance\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp class=\"h4\"\u003eReplace when O-Ring shows compression set, cracking, swelling, or physical damage\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp class=\"h4\"\u003eVerify tool model and serial number at milwaukeetool.com before ordering to confirm compatibility\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp class=\"h3\"\u003e\u003cb\u003eSpecifications\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"h4\"\u003e\n  \u003cstrong\u003eBrand:\u003c\/strong\u003e Milwaukee Tool\u003cbr\u003e\n  \u003cstrong\u003ePart Number:\u003c\/strong\u003e 34-40-0900\u003cbr\u003e\n  \u003cstrong\u003eType:\u003c\/strong\u003e O-Ring Sealing Component\u003cbr\u003e\n  \u003cstrong\u003eMaterial:\u003c\/strong\u003e Rubber\u003cbr\u003e\n  \u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003cbr\u003e\n  \u003cstrong\u003eCompatible Tools:\u003c\/strong\u003e Milwaukee Power Tools (verify model and serial number)\u003cbr\u003e\n  \u003cstrong\u003eUPC:\u003c\/strong\u003e 045242097623\n\u003c\/p\u003e\n\n\u003cp class=\"h3\"\u003e\u003cb\u003eIncludes\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"h4\"\u003e\n  (1) Milwaukee O-Ring (34-40-0900)\n\u003c\/p\u003e","brand":"Milwaukee Tool","offers":[{"title":"Default Title","offer_id":53474039333177,"sku":"MLW-34-40-0900","price":1.72,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0145\/2333\/4742\/files\/34-40-0900-2__34928.1727441912.jpg?v=1781630811","url":"https:\/\/mprtools.com\/products\/milwaukee-tool-34-40-0900-o-ring","provider":"MPR Tools \u0026 Equipment","version":"1.0","type":"link"}
