For optimum leak control in automotive plumbing, use Earl’s Port hose ends! These AN port hose ends are available in straight, 30, 45, 60 and 90 degrees. By using an O-ring, a positive seal is created and also eliminates an extra fitting giving you some extra clearance. These AN port hose ends make it easy to plumb fuel rails, overflow tanks, dry sump engines and fuel systems. These are slimmer and shorter in length than a standard style hose ends. These hose ends eliminate the need for an adapter so they provide a lower profile where space is limited. The traditional hex sizes have also been reduced to save weight and the port side is contoured for increased flow. Lighter-weight and fewer components is always the best way of organizing your vehicle. Select models have Dynamic Swivel™ technology which allows for 360 degrees of rotation of installed line after installation! The high flow designed hose ends withstand harsh environments, including vibration and extreme pressures! Available for use in Swivel-Seal, UltraPro and Ultra-flex hose. Next time your making upgrades to your vehicle, make sure you're using the right plumbing hose ends. For more Earls plumbing products visit EarlsPlumbing.com
