Cleco 55PTHHA403 Shut-Off Model Hydraulic Pulse Tool | H Series | Pistol Grip | 4000 RPM | 3/8" Square Drive | 22.1 - 22.1 (ft-lbs) Torque Range

Built for controlled fastening on production assemblies, the Cleco 55PTHHA403 H Series Shut-Off Hydraulic Pulse Tool combines a 3/8" square drive, 4,000 RPM clockwise idling speed, and a manufacturer-published 22.1–40.6 ft-lbs recommended torque range for tightening M10 fasteners in repetitive assembly work. The hydraulic pulse mechanism delivers torque in short oil-cushioned pulses, helping reduce the reaction force felt by the operator compared with conventional impact-style fastening. The shut-off model is intended to stop at the preset torque, supporting repeatable fastening where consistency matters across multiple rundowns.

The pistol grip configuration gives technicians a familiar trigger-style layout for horizontal and bench-level fastening, while the H Series format is suited to manufacturing cells, tool cribs, and assembly stations that need dependable pneumatic fastening without moving into a fully electric tool platform. With 15.89 ft³/min pulse air consumption, 1/4-18 NPT air inlet, and 2.67 lb tool weight, the 55PTHHA403 is a compact production fastening tool for buyers matching torque range, drive size, and plant air capacity before ordering.

Type: Shut-Off Hydraulic Pulse Tool | Series: H Series | Model: 55PTHHA403 | Grip Style: Pistol Grip | Drive Type: Square | Drive Size: 3/8" Square | Recommended Torque Range: 22.1–40.6 ft-lbs / 30–55 Nm | Free Speed: 4,000 RPM clockwise / 6,000 RPM anticlockwise | Fastener Capacity: M10, grade 8.8 | Weight: 2.67 lb / 1.21 kg | Air Consumption at Idle: 5.3 ft³/min / 0.15 m³/min | Air Consumption at Pulses: 15.89 ft³/min / 0.45 m³/min | Air Inlet: 1/4-18 NPT

Features:

• Hydraulic pulse mechanism helps reduce reaction force during fastening, making it useful for repetitive assembly work where impact wrench feedback would be excessive.
• Shut-off model stops the rundown at the preset torque, supporting more consistent fastening than manual trigger control alone.
• 3/8" square drive accepts compatible square-drive sockets for M10 assembly applications within the tool’s recommended torque range.
• 4,000 RPM clockwise idling speed supports fast run-down before the tool reaches torque, helping improve cycle time in production stations.
• Pistol grip body provides a familiar hand position for bench assembly, fixture-side work, and horizontal fastening tasks.
• Compact 2.67 lb tool weight helps reduce handling fatigue when the tool is used repeatedly across shift work.
• Published pulse air consumption of 15.89 ft³/min helps buyers confirm compressor and FRL capacity before adding the tool to a workcell.

Applications:

• Automotive assembly — fastening M10 hardware on subassemblies, brackets, frames, and production-line components where repeatable torque shut-off is required.
• Industrial manufacturing — controlled bolt tightening in workcells, fixture stations, and plant assembly areas using compressed air systems.
• Appliance and equipment assembly — running down medium-size fasteners where low reaction force and consistent shut-off improve operator workflow.
• Aerospace and transportation production — repetitive fastening tasks where tool weight, reaction control, and torque range must be matched to the joint.
• MRO and maintenance tool cribs — replacement or standardization tool for facilities already using Cleco H Series hydraulic pulse tools.

FAQs:

• Q: What is a hydraulic pulse tool?
  A: A hydraulic pulse tool uses an oil-filled pulse unit to deliver torque in controlled bursts. This helps reduce the reaction force transferred to the operator compared with many impact-style tools.
• Q: What does shut-off model mean on the 55PTHHA403?
  A: Shut-off means the tool is intended to stop the rundown when the preset torque is reached. This helps improve fastening repeatability in production assembly compared with relying only on operator feel.
• Q: What torque range should I use for this tool?
  A: The manufacturer-published recommended torque range is 22.1–40.6 ft-lbs, or 30–55 Nm. Always confirm the final torque setting with your plant’s joint testing, torque audit process, and application requirements.
• Q: What socket type fits this model?
  A: This SKU uses a 3/8" square drive, so it requires compatible 3/8" square-drive sockets rated for the fastening application.
• Q: Is this the right tool for general automotive repair or DIY use?
  A: This is a production assembly pulse tool, not a general breakaway impact wrench. It is best suited to controlled tightening applications, not removing rusted lug nuts or high-torque service fasteners.
