Cleco 400PHF356 Pistol Grip High Torque Pneumatic Pulse Tool | Non Shut-Off | 3,500 RPM | 185 - 295 (ft-lbs) Torque Range | 3/4" Square Drive

Built for the upper end of Cleco’s high-torque pneumatic pulse tool range, the Cleco 400PHF356 pistol grip pulse tool delivers a 185 - 295 ft-lbs torque range for large fasteners used in machinery assembly, heavy equipment production, and high-load industrial MRO. Its hydraulic pulse mechanism (a sealed pulse unit that delivers torque in short hydraulic impulses instead of continuous twisting force) helps reduce reaction at the operator’s hand compared with conventional impact-style fastening. The 3/4" square drive fits compatible impact-rated sockets, while the 3,500 RPM free speed provides fast rundown before the tool reaches its working torque range.

As a non shut-off model, the 400PHF356 gives the operator manual control over the pulse cycle rather than automatically stopping at a preset torque. This makes it a strong fit for production and service environments where torque is confirmed through the shop’s established verification process. With a 5.2 kg tool weight, 3/8" air inlet, 1/2" minimum hose I.D., and 42.3 air consumption, this model should be matched with a compressed air system sized for repeated high-torque fastening.

Tech Tip: To increase tool performance, extend tool life, and lessen repair costs, use it with a Filter-Regulator-Lubricator FRL)

Applications:

• Heavy equipment assembly: Fastening large brackets, mounts, housings, and fabricated subassemblies where 250 - 400 Nm torque capacity is required.
• Industrial production lines: High-torque bolt-up work on machinery frames, equipment skids, fixtures, and structural assemblies.
• Plant maintenance and MRO: Repeated fastening on conveyors, pumps, guards, and large machinery components where reduced reaction force helps the technician stay in control.
• Fleet and truck service facilities: Controlled fastening on larger service components when the air system and torque verification process are suitable for pulse tools.
• Production repair and rework stations: High-load fastening jobs that need a 3/4" square drive tool with manual pulse-cycle control.

FAQs:

• Q: What does “non shut-off” mean on the Cleco 400PHF356?
  A: Non shut-off means the tool does not automatically stop when a preset torque is reached. The operator controls the fastening cycle, and final torque should be checked using the facility’s approved torque verification method when documentation is required.
• Q: How does the 400PHF356 compare with the 250PHF406?
  A: The 400PHF356 covers a higher 185 - 295 ft-lbs torque range, while the 250PHF406 is listed at 118 - 185 ft-lbs. Choose the 400PHF356 when the joint requires the top end of the C Series non shut-off high torque range.
• Q: What type of sockets should be used with this tool?
  A: Use properly sized 3/4" drive impact-rated sockets. Standard chrome hand sockets are not intended for powered pneumatic fastening tools.
• Q: Is a pulse tool the same as an impact wrench?
  A: No. A pulse tool uses a hydraulic pulse unit to apply torque in controlled impulses, which generally produces less reaction at the handle than a conventional impact wrench. It is commonly used for assembly fastening rather than breakaway removal work.
• Q: Is the Cleco 400PHF356 suitable for a home garage?
  A: This model is a high-torque industrial pneumatic pulse tool with substantial air demand. Most home garages will not have the compressor capacity, air plumbing, or torque-control process needed to use it effectively.
