Aeroflow?s male adapter 570 series PTFE style hose ends are designed to allow the hose end to be threaded directly into the female port without the extra cost and complication of an adapter fitting. Made from 6061-T6 aluminium, this design ensures a secure, leak free connection every time. Aeroflow?s corrosion resistant, colour consistent, hard anodised (expect silver) adds the final touch quality and protection you have come to expect from Aeroflow.
