Series Overview
AS568 200 Series groups 84 AS568 dash numbers (201–284) sharing a 0.139" (3.53 mm) cross section. Inside diameters span 0.171" to 17.955" ID (4.3–456.1 mm). These sizes dominate heavy machinery, large cylinders, process equipment because the 3.53 mm cord diameter balances conformability, extrusion resistance, and groove width in standard SAE and industrial glands.
