Chicago Pneumatic 8941078306 3/8 in Air Ratchet 10-90 Ft/lb

Product Description

The CHICAGO PNEUMATIC 8941078306 is a 3/8 inch drive pneumatic air ratchet designed for professional fastening and removal work in automotive, industrial, and mechanical service environments. It delivers 10 to 90 ft/lb of torque through an inline handle configuration, making it well-suited for tight spaces where a standard right-angle ratchet cannot reach. The tool operates at 90 psi with an air consumption of 5 CFM, drawing from a 1/4 inch NPTF inlet. At 2.7 pounds and 12 inches in overall length, it balances reach and manageability for extended use on the shop floor or in the field.

This air ratchet is intended for use by automotive technicians, fleet mechanics, and general industrial maintenance professionals. The inline handle design keeps the tool low-profile along the axis of the fastener, which is particularly useful when working inside engine bays, under dashboards, or in confined mechanical assemblies. It is compatible with standard 3/8 inch drive sockets and is sized to work with most shop air compressor systems delivering 90 psi line pressure.

Key Features

• 3/8 inch drive accepts standard 3/8 inch drive impact and hand sockets
• 10 to 90 ft/lb torque range handles a wide variety of fastener sizes
• Inline handle keeps the tool profile low in confined spaces
• 190 RPM free speed for fast socket cycling between fasteners
• Side exhaust directs air away from the work area
• 1/4 inch NPTF inlet connects to standard shop air fittings

Compatibility

Designed for use with standard 3/8 inch drive sockets. Requires a shop air supply capable of delivering at least 90 psi at 5 CFM through a 1/4 inch air line fitting.

Installation Notes

Installation and use should be performed by a qualified mechanic or technician familiar with pneumatic hand tools. Before connecting to an air supply, verify that line pressure does not exceed the tool rated maximum of 90 psi. Use a properly sized air fitting and confirm the 1/4 inch NPTF inlet connection is secure and free of leaks before operation. Always depressurize the air line before disconnecting the tool.
