Aeroflow’s 150 Series Taper fittings are a CNC machined one piece fitting which provide uninterrupted flow. The taper design 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. The tight mandrel bent radius body has superior wall thickness and a swivel head allowing 360° rotation to allow for easy adjustment. Aeroflow’s 150 series fittings are a must for any serious racer for use in fuel systems, cooling systems, vacuum applications and oil systems. Compatible hose: 100 Series S/S braid, 450 Series Lightweight Nylon Braid Note: Not compatible for power steering and automatic transmission line applications. Hose ends are hard anodized (excluding silver finish).
