In addition, this precision replacement directly replaces OEM part numbers \u003cstrong\u003e624677\u003c\/strong\u003e and \u003cstrong\u003e624786\u003c\/strong\u003e. Friction and continuous heat gradually wear down internal seals over time. Consequently, worn cup seals trigger low-oxygen alarms, cause sluggish pressure build-up, and create cylinder blow-by. Installing this precision PTFE cup seal (SKU: T-5002) quickly re-establishes a tight mechanical seal.\u003c\/p\u003e\n\u003ch2\u003eInvacare Platinum 5 Piston Cup Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e Directly replaces OEM part numbers \u003cstrong\u003e624677\u003c\/strong\u003e and \u003cstrong\u003e624786\u003c\/strong\u003e, as well as factory cup seals in Thomas repair assemblies (SKU: T-5002).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Fitment:\u003c\/strong\u003e Engineered specifically for Thomas 2650 and 2660 compressor models used in Invacare Platinum 5 concentrators.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable PTFE Material:\u003c\/strong\u003e Resists intense operating heat and friction for prolonged compressor service life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRestores Compression:\u003c\/strong\u003e Eliminates pressure drop across the cylinder head to ensure accurate sieve bed cycling.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eInstallation \u0026amp; Compressor Service Advice\u003c\/h2\u003e\n\u003cp\u003eFirst, inspect your cylinder sleeves when replacing this \u003cstrong\u003eInvacare Platinum 5 piston cup\u003c\/strong\u003e. If the sleeve walls show scoring or deep ridges, a new piston cup cannot seal properly. In addition, Thomas 2650 and 2660 compressors operate with twin cylinder heads. Therefore, technicians always recommend replacing both piston cups at the same time to balance airflow.
