This quality 9/16" open-end aluminum wrench will minimize marring of the anodized finish on your aluminum 4AN hose ends. It is made from a special heat-treated alloy that resists springing open under normal use. The handle length is designed to prevent damage to fittings caused by over-tightening. The AN size is etched on the handle for quick identification. Handle design may vary from photo.
This size is included in our 6-Piece 4AN to 16AN Hose End Wrench Set, Part No. 3830-416.
