LE-R251B 3/8" Mini Air Ratchet — 25 ft-lb, 6.7", Triple Planetary, 1.23 lbs
The Le Lematec LE-R251B is built for the spaces where standard ratchets can't go. At 6.7" long and 1.23 lbs, it slips into under-dash areas, engine bays, and transmission tunnels with ease — delivering 25 ft-lb through a triple planetary gear system that handles 80% of under-hood fasteners without breaking a sweat.
Key Features
- Ultra-Compact 6.7" Length: Fits into under-dash areas, engine bays, and transmission tunnels where standard ratchets cannot reach
- Only 1.23 lbs: Lightest air ratchet in the Le Lematec lineup — reduces hand and wrist fatigue during all-day use
- 25 ft-lb Max Torque (34 N-m): Handles valve covers, intake manifolds, interior trim fasteners, and light suspension components
- Triple Planetary Gear System: 3-stage gear reduction delivers smooth, consistent torque with minimal vibration
- 250 RPM Free Speed: Fast enough for efficient bolt removal, controlled enough for precision tightening
- Front Exhaust: Directs air away from the work surface and operator
- Standard 3/8" Square Drive: Accepts all 3/8" sockets, extensions, and adapters (SAE and metric)

Frequently Asked Questions
What air compressor do I need for the LE-R251B?
This tool requires approximately 5+ CFM at 90 PSI. A 20-gallon tank handles intermittent use; a 30+ gallon tank is recommended for continuous operation.
Is the LE-R251B compatible with my existing air setup?
Yes. It uses a standard 1/4" NPT air inlet fitting compatible with most compressors, hoses, and quick-connect couplers from any manufacturer.
Is 25 ft-lb enough torque for automotive work?
Yes, for most fasteners. 25 ft-lb handles 80% of under-hood bolts, interior trim fasteners, valve covers, intake manifolds, and light suspension components. For lug nuts and suspension bolts requiring 80+ ft-lb, step up to the LE-R2150B (75 ft-lb) or LE-R2550B 1/2" ratchets.
What makes this better than a cordless electric ratchet?
Air ratchets deliver consistent torque without battery fade, weigh less (no battery pack), and have a slimmer profile. The LE-R251B at 1.23 lbs is typically half the weight of an equivalent cordless ratchet. Air tools also last longer — no battery cells to degrade over time.
Can I use impact sockets with this air ratchet?
Air ratchets generate torque through smooth rotation (not impacts), so standard chrome sockets are safe to use. Impact sockets also work and provide extra durability. The 3/8" drive accepts any standard or deep socket, universal joints, and extension bars.
