Aeroflow's 100 Series Taper fittings are a braised full flow fitting with a taper design that provides straight through connection with easy alignment. Upon assembly, a tube end compresses the hose into a purpose designed socket allowing for a leak free fitting. All angles are mandrel bent, eliminating sharp changes in direction for optimum flow. Our 100 Series fittings allows 360° rotation to allow for easy adjustment making them and an excellent choice for the automotive enthusiast for use in fuel systems, cooling systems, vacuum applications and oil systems. Compatible hose: 100 Series Stainless Steel braid and 450 Series Lightweight Nylon braid.
