CP6613 3/4 inch pneumatic stall torque nutrunner with S-type reaction bar for industrial bolting

CP6613 - 3/4" Stall Torque Pneumatic Nutrunner

High-Torque Precision Meets Industrial Durability

The CP6613 is a high-performance 3/4" pneumatic torque wrench engineered for the most demanding bolting environments. Designed specifically for the Oil & Gas, Power Generation, and Heavy Industrial sectors, this tool is a key part of our Pneumatic Torque Multipliers range, delivering a powerful 1,300 Nm (959 ft.lbf) capacity without compromising on operator safety.

Featuring a rugged composite housing and a high-performance vane-type motor, the CP6613 provides a superior power-to-weight ratio. Its non-shut-off stall system ensures consistent torque delivery, while the ultra-low vibration levels (<2.5 m/s²) allow for extended operation without user fatigue. Whether you are managing flange bolting or heavy machinery maintenance, the CP6613 offers the accuracy (±5 %) and reliability required for mission-critical joints.

Key Benefits

Built for Tight Spaces

Compact dimensions and a 3/4" drive make it the go-to tool for high-torque applications in restricted areas.

Operator Ergonomics

A lightweight design (only 3.7 kg without the reaction arm) combined with a swiveling pistol grip handle and a one-finger reverse mode.

High Performance

As a leader among professional Torque Multipliers, it utilizes an air motor that mimics impact speed with steady, continuous rotation.

Precision Control

Use with an industrial FRL (Filter-Regulator-Lubricator) ATC pack to achieve maximum accuracy and tool longevity.

Frequently Asked Questions: CP6613 Pneumatic Nutrunner

1What is the best air pressure for an industrial pneumatic nutrunner like the CP6613?

To reach the max torque of 1,300 Nm (959 ft.lb), the tool requires 90 psi (6.3 bar) of dynamic air pressure. Note that this must be measured at the tool inlet while the trigger is pulled. Setting 90 psi "static" pressure at the compressor is often insufficient, as pressure drops occur across the hose length. Using an FRL (Filter-Regulator-Lubricator) is essential to maintain the ±5% accuracy and ensure the gearbox reaches its 13,000-cycle service life.

2How does a CP6613 pneumatic nutrunner compare to other models?

The CP6613 is distinguished by its power-to-weight ratio and compactness. Weighing only 4.4 kg (9.7 lbs) with the reaction arm, it is significantly lighter and easier to maneuver in tight spaces than hydraulic equivalents. Compared to impact wrenches, the CP6613 provides smooth, continuous rotation without the "hammering" effect, which results in far higher accuracy, lower noise (101 dB), and ultra-low vibration levels (<2.5 m/s²), protecting the operator from long-term injury.

3What are the best pneumatic nutrunners similar to CP6613 for industrial assembly?

If your application requires higher torque than the 1,300 Nm provided by the CP6613, the next steps in this high-performance series are the CP6626 (2,600 Nm) and the CP6641 (4,100 Nm). These models share the same rugged composite housing, vane-type motor, and stall-torque technology, providing a consistent user experience across different bolt sizes and torque requirements on the same assembly line.

4Are these pneumatic nutrunners recommended for heavy-duty assembly lines?

Yes. The CP6613 is specifically engineered for high-cycle, heavy-duty environments like Oil & Gas, Power Generation, and Mining. Its gearbox is rated for 13,000 cycles before requiring major maintenance, and the vane-type motor is designed to run cooler than electric alternatives. This makes it ideal for repetitive flange bolting or structural assemblies where tool overheating and downtime are not options.

5Where can I buy CP6613 style pneumatic nutrunners in the US?

You can purchase the CP6613 and its associated accessories directly through TorqLite. Buying manufacturer-direct ensures you receive a genuine tool with full warranty coverage, access to specialized S-type or custom reaction arms, and professional calibration services. Our technical team can also provide the specific Air Pressure-to-Torque charts required to operate your tool accurately in the field.
