At $13.09 per foot, this is the correct material when larger single-stage or two-stage reciprocating compressors call for a bore between standard 1\/2\" and 3\/4\" for their discharge connections, inter-cooler tubes, or aftercooler connections. If your Castair system documentation or existing installation uses 5\/8\" copper, CT58 is the factory-correct replacement material.\u003c\/p\u003e\n\n\u003ch3\u003eWhere 5\/8\" Copper Tubing Is Used\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDischarge connections on larger compressor heads:\u003c\/strong\u003e Some Castair configurations use 5\/8\" copper for the discharge tube run from head to tank check valve\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInter-stage tubing on two-stage machines:\u003c\/strong\u003e The plumbing between first and second stage may require 5\/8\" depending on the compressor CFM and inter-cooler design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAftercooler inlet\/outlet connections:\u003c\/strong\u003e Medium-capacity aftercooler units may call for 5\/8\" connection tubing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom Castair compressor configurations:\u003c\/strong\u003e Castair builds custom systems; 5\/8\" copper is available for specifications requiring this diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy Copper for Discharge Connections\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature:\u003c\/strong\u003e Compressed air at compressor head discharge reaches 200-350°F.
