Manufactured in the United States under CAGE code 97153, this backup ring is an OEM replacement component available as a single unit. ECCN classification is 9A991.d and Schedule B code is 3926904500.\u003c\/p\u003e\u003cp\u003ePTFE backup rings prevent O-ring extrusion and support sealing integrity within hydraulic brake systems operating under the pressure and temperature conditions of aircraft landing and ground operations. The low friction and chemical resistance of PTFE against aviation hydraulic fluids make it well suited to the sealing environment of aircraft brake hydraulic circuits. In service, the backup ring seats between the O-ring and the low-pressure side of the sealing gap, physically blocking the annular clearance that the O-ring could otherwise be forced into under pressure. The 68-1416 measures 1.40 x 1.40 x 0.10 inches and is 8130-3 eligible for FAA maintenance documentation. This part ships as a single unit ready for installation per the applicable brake assembly component maintenance manual.\u003c\/p\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e68-1416\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eGoodrich Wheel \u0026amp; Brake\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Type\u003c\/td\u003e\n\u003ctd\u003ePTFE Backup Ring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePTFE (Polytetrafluoroethylene)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (L x W x H)\u003c\/td\u003e\n\u003ctd\u003e1.40 x 1.40 x 0.10 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUnited States\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eECCN\u003c\/td\u003e\n\u003ctd\u003e9A991.d\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSchedule B\u003c\/td\u003e\n\u003ctd\u003e3926904500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Goodrich Wheel and Brake","offers":[{"title":"Default Title","offer_id":46095076688008,"sku":"68-1416","price":69.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0331\/9391\/8600\/files\/noimage_2048x2048_6d9725a0-1ef3-4574-89d1-f6034ff9729a.webp?v=1780934691","url":"https:\/\/www.pilotshq.com\/products\/goodrich-wheel-brake-ptfe-backup-ring-68-1416-oem-replacement","provider":"Pilots HQ LLC.","version":"1.0","type":"link"}
