Ingersoll/Rand MiniMUTT Mobile Universal Trailer Tester hand tool

Compact Pneumatic Ratchet for Trailer Testing

The Ingersoll Rand MiniMUTT is a new pneumatic ratchet built for mobile universal trailer testing. It delivers an extra measure of durability through an advanced head design suited to automotive and fleet maintenance tasks. The 3/8-inch drive accepts standard sockets for fastener work on trailer lighting and brake circuits. This hand tool targets technicians who need a portable, air-powered solution for on-site diagnostics.

Adjustable Exhaust and Variable Speed Control

A 360º adjustable exhaust directs air away from the operator and the workpiece, keeping the area clear during extended use. The variable speed lever-style throttle lets the user match torque delivery to each fastener without switching tools. Connection is via a 1/4-inch NPT inlet that fits a 5/16-inch hose, so the ratchet integrates with common shop air lines. The compact head profile improves access in tight trailer harness channels.

Torque Range Defines the Application Window

Output spans 10 ft-lbs to 50 ft-lbs, setting the practical limit for fasteners this ratchet can tighten or loosen. Jobs requiring higher breakaway torque or precision inch-pound settings fall outside that window. Technicians who regularly service heavy-duty wheel ends or suspension bolts will need a larger drive tool. The 50 ft-lbs ceiling makes it a specialist for lighting, wiring and lighter chassis hardware on trailers.
