This precision component is classified under FSCG 1630, the federal supply group for Aircraft Wheel and Brake Systems, and carries NSN 1630-01-332-5499. Manufactured in the United States under CAGE code 97153, it is FAA TSO approved and 8130-3 eligible for use in documented FAA maintenance programs.\u003c\/p\u003e\u003cp\u003eSeal retainers in aircraft brake systems hold hydraulic or pneumatic seals in position within the brake piston bore or cylinder, preventing seal extrusion and maintaining consistent sealing performance under the hydraulic pressure cycles experienced during repeated brake applications in airline and general aviation service. Loss of seal containment in a brake piston can result in brake fluid leakage, reduced braking effectiveness, or total brake loss, making the seal retainer a functionally significant element of the brake assembly. The 56-873 measures 0.81 x 0.81 x 0.18 inches and weighs 0.01 lb. ECCN is 9A991.d and HTS code is 8807200010.\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\u003e56-873\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\u003eSeal Retainer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNSN\u003c\/td\u003e\n\u003ctd\u003e1630-01-332-5499\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFSCG\u003c\/td\u003e\n\u003ctd\u003e1630 — Aircraft Wheel and Brake Systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (L x W x H)\u003c\/td\u003e\n\u003ctd\u003e0.81 x 0.81 x 0.18 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.01 lb\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\u003eFAA Approval\u003c\/td\u003e\n\u003ctd\u003eTSO\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\u003e8807200010\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Goodrich Wheel and Brake","offers":[{"title":"Default Title","offer_id":46095077703816,"sku":"56-873","price":94.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0331\/9391\/8600\/files\/noimage_2048x2048_38b57d7b-714e-4117-9277-93cb1ea46acd.webp?v=1780934691","url":"https:\/\/www.pilotshq.com\/products\/goodrich-wheel-brake-seal-retainer-56-873-oem-replacement","provider":"Pilots HQ LLC.","version":"1.0","type":"link"}
