The Wolf-Pak® Disinfecting Cap covers the needleless connector and protects it from touch and airborne contamination after it's been applied. The Wolf-Pak® Disinfecting Cap contains 70% Isopropyl Alcohol (IPA) as a disinfectant solution and when applied to the needleless connector, between line accesses, the IPA bathes the connector's top and threads.
