Pro-source 5550008145PRO Air Ratchet 3/8 in Drive 50 Ft/lb

Product Description

The PRO-SOURCE 5550008145PRO is a 3/8 inch drive pneumatic air ratchet built for professional fastening work in tight quarters. It delivers up to 50 ft/lb of torque and operates at 150 RPM, making it effective for repetitive fastener removal and installation. The inline handle design keeps the tool compact and well-balanced in confined spaces. It connects via a 1/4 inch NPT inlet and requires 4 CFM of air flow at 90 psi to operate. Technicians in automotive, industrial, and mechanical trades rely on this type of tool for speed and control in production and service environments.

This air ratchet is suited for automotive service bays, equipment maintenance, assembly lines, and general mechanical work where a standard ratchet is too slow or a larger air impact would be impractical. The 3/8 inch drive accepts a wide range of standard sockets, making it versatile across common fastener sizes encountered in light to medium-duty applications.

Key Features

• 3/8 inch drive size compatible with standard socket sets
• 50 ft/lb maximum torque output for light to medium fastening tasks
• Inline handle design for improved access in confined spaces
• 1/4 inch NPT air inlet for standard shop air connections
• 150 RPM operating speed for fast fastener removal and installation
• Requires 4 CFM at 90 psi — compatible with most shop compressor setups

Compatibility

Designed for use with 3/8 inch drive sockets and standard 1/4 inch NPT air line fittings commonly found in automotive and mechanical service environments.

Installation Notes

This tool is installed by connecting the 1/4 inch NPT inlet to a regulated shop air supply — verify supply pressure is set to 90 psi before use. Ensure the air line is depressurized before attaching or removing the tool from the air supply. Lubricate the air inlet with pneumatic tool oil regularly to maintain internal components. Always use sockets rated for impact or air ratchet service to prevent socket failure under load.
