1/2" Drive Air Ratchet for General Duty
The Ingersoll/Rand 1077XPA is a 1/2 inch square drive air ratchet built for general duty fastening. It runs on compressed air at 90 psi and delivers a free speed of 160 RPM. The tool suits technicians who need a compact pneumatic option for routine bolting tasks.
54 ft-lb Fastening Torque with 73 ft-lb Maximum
The ratchet produces 54 ft-lb of fastening torque and peaks at 73 ft-lb maximum torque. That output handles many standard automotive and maintenance fasteners comfortably. Higher torque applications or seized hardware will exceed the tool's capability and require a larger impact wrench or breaker bar.
Ball Detent Retainer and Bottom Exhaust
A ball detent retainer holds sockets securely on the 1/2 inch drive during operation. The bottom exhaust directs air away from the work area and the operator's hands. At 11 inches overall length and 2.8 lb weight, the ratchet fits into confined engine bays and reduces fatigue during extended use.

Questions about this item
Will the 1/2" square drive and 90 psi air inlet work with my existing 3/8" hose and compressor?
The tool requires a minimum 3/8" hose and a 1/4" NPT female air inlet at 90 psi; your compressor must maintain that pressure continuously for the rated 160 RPM free speed.
How can I verify the wrench is delivering the specified 54 ft-lb fastening torque after installation?
Run the tool at 90 psi with a calibrated torque transducer or a known-calibrated click wrench on the same fastener; the reading should reach 54 ft-lb before the ratchet stalls.
Does the box include the 1/4" NPT fitting and 3/8" hose, or must I purchase them separately?
The supplied unit is the ratchet only; the 1/4" NPT air inlet fitting and a minimum 3/8" ID air hose are not included and must be sourced separately.
