The PRO-SOURCE 5550008445PRO is a 1/2 inch drive inline air ratchet designed for professional use in automotive, mechanical, and industrial service environments. Powered by compressed air at 90 psi, it delivers up to 50 ft-lb of torque and operates at 150 RPM, making it well suited for fastener removal and installation in tight spaces. The inline handle design keeps the tool compact and allows access to areas where a standard bulky ratchet head would not reach. Air consumption is rated at 4 CFM, which is compatible with most shop compressor setups. Licensed mechanics, fleet technicians, and industrial maintenance trades are the primary installers of this tool.
This air ratchet is intended for use in automotive repair shops, fleet maintenance bays, manufacturing facilities, and general mechanical service applications. The 1/4 inch NPT inlet is a standard size that connects directly to common shop air lines and quick-connect fittings without adapters in most setups. The inline handle style suits underhood work, undercarriage service, and any confined-space fastening task where a right-angle or pistol-grip tool is less practical.
Designed for use with standard 1/2 inch drive sockets and connects to shop air lines via a 1/4 inch NPT fitting. Compatible with air supply systems operating at 90 psi.
Installation and operation should be performed by qualified mechanics or technicians familiar with pneumatic hand tools. Before connecting to an air line, verify the supply pressure does not exceed the rated 90 psi operating pressure. Always use a properly rated air hose and quick-connect fitting sized for the 1/4 inch NPT inlet. Lubricate the tool periodically through the air inlet with pneumatic tool oil to maintain internal components and extend service life.
