Grey Pneumatic 1146ql Impact Extension 3/8 in Drive 6 in

Product Description

The GREY PNEUMATIC 1146ql is a 6-inch impact extension designed for use with 3/8-inch drive impact wrenches and impact ratchets. It transfers torque between an impact tool and a socket while absorbing the shock loads that standard extensions cannot handle. The 1146ql uses either a retaining ring or a pin-and-O-ring retention system to keep the socket locked during high-vibration operation. This extension is built to industrial specifications, making it suitable for production, fleet, and field applications where impact-rated tooling is required.

This extension is used in automotive, truck, and light industrial repair environments where a 3/8-inch drive impact tool is the primary fastening tool. It suits applications where the fastener is recessed or where direct tool-to-socket contact is impractical due to clearance constraints. Technicians working on suspension components, exhaust systems, engine accessories, and similar assemblies will find this extension useful in day-to-day impact work.

Key Features

• 3/8-inch drive size compatible with standard 3/8-inch impact sockets and impact tools
• 6-inch length provides clearance for recessed or deep-set fasteners
• Retaining ring or pin-and-O-ring socket retention prevents socket dropout during impact use
• Engineered to industrial impact specifications to withstand high-cycle torque and vibration loads
• SAE standard sizing for compatibility with SAE socket sets

Compatibility

Designed as an impact-rated extension for use with 3/8-inch drive impact wrenches, impact ratchets, and compatible impact sockets in SAE applications.

Installation Notes

This extension is installed and removed by hand — no additional tools are required for attachment. Confirm the socket is fully seated and the retaining ring or pin-and-O-ring is engaged before applying tool power. Impact extensions should only be paired with impact-rated sockets, not standard chrome hand-tool sockets. Inspect the extension for cracks or deformation before each use and replace any damaged extension immediately.
