Proflow’s AN o-ring boss (ORB) to AN adaptor fittings are one of our most popular fittings to date. These fittings provide a leak-free seal by utilizing an NBR o-ring, which should only be used in o-ring boss styled ports. They are double anodised to stand up to harsh automotive conditions and are available in a huge range of colours and sizes.
