3/8-Inch x 12-Inch Pneumatic Extension

This BLU-MOL 6558 extension adds 12 inches of reach to 3/8-inch drive pneumatic tools. It connects directly between an impact socket and an air ratchet or impact wrench. The accessory is supplied new and suits professional automotive and industrial maintenance tasks.

Mechanics needing extra reach on 3/8-inch drive

Technicians working in tight engine bays or around suspension components gain the clearance this extension provides. Users whose tools already have sufficient reach, or who require a different drive size, will not benefit from this specific length and diameter.

3/8-Inch Drive Size Compatibility

The extension fits 3/8-inch square-drive sockets and anvils only. Verify that both the air tool and the socket share this drive size before purchase, as the part will not connect to 1/4-inch or 1/2-inch drive equipment.

Questions about this item

How far does the 12 in extension reach from the impact driver?

The extension adds 12 in of reach from the driver chuck to the socket, letting you access deep or recessed fasteners without a longer tool.

Does the 3/8 in drive extension heat up or vibrate during continuous impact use?

The steel extension transmits impact force directly; it runs at ambient temperature and vibration matches the driver, so no extra heat or noise is generated by the extension itself.

What drive size must my impact driver and sockets already have to use this 6558 extension?

Both the impact driver anvil and the sockets must be 3/8 in drive; the extension has a 3/8 in male square on one end and a 3/8 in female square on the other.
