NotcHead’s AN Wrench Inserts are the safe and smart way to wrench on AN fittings without damaging them.

Made from Delrin, the inserts slide into your SAE open-end wrenches and take the stress from the fittings, allowing you to loosen and tighten them to your heart’s content without hurting them.

The inserts are sold in a set of six in the following sizes:

  • -3 AN
    • -4 AN
    • -6 AN (includes both the -6 AN insert plus a ¾in insert for the other side of the fitting)
    • -8 AN
    • -10 AN
