SPEEDAIRE PN21AA313G Keyless Chuck

The SPEEDAIRE PN21AA313G is a keyless chuck designed for use with compatible Speedaire air compressor accessories. It suits technicians and DIY users who need quick bit changes without a separate key.

Tool-free fitting with Grainger 21AA72 match

The chuck installs by hand onto the matched Grainger part number 21AA72, removing the need for a chuck key. Cross-threading the threads during hand-tightening is the most common issue, so start the engagement squarely and advance slowly.

Verify thread compatibility before ordering

Confirm that your existing accessory carries the Grainger 21AA72 designation so the threads align with this chuck. The product carries California Proposition 65 warnings for chemicals linked to cancer and reproductive harm.
