Medical/Surgical Tubing Formulation ND-100-65 (http://emurdock.com/medicalsurgicaltubingformulationnd-100-65.aspx)

They have both 50 and 100' foot lengths of various diameters... not sure if it is the type you are looking for... I don't think it is too surprising that you aren't getting many responses to such an esoteric inquiry. ;)
