USAG Manual Oil Syringe (421M/376A) - Capacity of 1/2 liter. Great for doing drivetrain fluid changes (std trans & differentials). Identical to the Facom 376A but at a lower price plus US warranty. The 421M/376A includes a delivery tube and 2 flex hoses.
The USAG U04210021 (Model 421 M) is a professional-grade manual fluid suction gun and oil syringe. Operating within the same Stanley Black & Decker industrial catalog family as the Facom 376A, this tool is optimized for extracting, transferring, and dispensing workshop fluids like motor oil, gear lubricants, antifreeze, and power steering fluid. Unlike the standard Facom variant which uses a single fixed metal snout, the USAG 421 M features a unique multi-hose modular configuration.
- Fluid Capacity: 500 cc (0.5 Liters)
- Body Material: Heavy-duty steel construction with a 57 mm diameter main tube
- Total Length: 340 mm
- Weight: 790 grams (~1.74 lbs)
- Nozzle Diameter: 10x12 mm steel nozzle base
Modular Accessories Included - The tool comes standard with a specialized plumbing kit to reach complex, deeply recessed fill plugs:
- Two PVC Flexible Hoses: One short length (75 mm) and one extended length (310 mm), both featuring a 15 mm outer diameter and a 10 mm inner diameter.
- One Precision Metal Tube: A 156 mm rigid metal tube (10 mm outer diameter / 6 mm inner diameter) designed to slip inside the PVC hose, providing structural rigidity for targeted, non-floppy fluid extraction.
Maintenance Note - The rear cover located just below the handle can be entirely unscrewed. This allows mechanics to slide out the inner plunger mechanism for quick cleaning, seal inspection, or re-greasing.
