Proto J175WP Air Impact Wrench 3/4 Inch Drive 1560 Ft/lb

Product Description

The PROTO J175WP is a 3/4 inch drive pneumatic impact wrench designed for heavy-duty fastening and removal tasks in automotive, industrial, and mechanical service environments. It delivers 1,560 ft/lb of torque at 5,300 RPM, making it suitable for high-torque applications such as suspension work, truck axle service, and heavy equipment maintenance. The pistol grip handle provides a familiar, controlled hold during operation. Air consumption is 5.1 CFM at 90 psi operating pressure, requiring a compressor and supply line sized appropriately for sustained use. The bottom exhaust directs spent air away from the work surface and the operator. Installation and operation are handled by mechanics, automotive technicians, and industrial maintenance professionals.

The J175WP is suited for shop and field applications where 3/4 inch drive tooling is standard. Common use cases include commercial truck service, heavy equipment repair, fleet maintenance, and industrial assembly lines. The 3/8 inch NPTF inlet connects to standard shop air lines. At 950 blows per minute, it maintains consistent impact energy under load. The pistol grip style makes it practical in tight bays or overhead positions where a bulkier D-handle would restrict movement.

Compatibility

Designed for use with 3/4 inch drive impact sockets and accessories. Connects to shop air systems via a 3/8 inch NPTF inlet at 90 psi operating pressure.

Installation Notes

Connection and operation are performed by qualified mechanics or pneumatic tool technicians. Ensure the air supply is regulated to 90 psi and that the supply line and fittings are rated for the required CFM before connecting. Verify the impact socket is fully seated and the retaining pin or ring is secured before applying torque. Always point the exhaust away from personnel and wear appropriate hearing protection, as this tool is rated at 98 dB during operation.
