HYTORC jGun Nutrunner

jGun Nutrunner – Pneumatic torque wrench

The revolutionary jGUN NUTRUNNER is the faster brother of jGUN DUAL SPEED. It is equipped with a heavy duty air motor, allowing it to reach speeds of up to 210 RPM with a torque of up to 700 Nm in ‘run-down’ mode. This makes the loosening of corroded bolts child’s play. While SPEED DUAL  is quick, NUTRUNNER is super quick!

As with DUAL SPEED, jGUN NUTRUNNER features the ‘twin torque’ system with ‘run-down’ mode for quickly turning nuts right up to the surface. ‘Torque mode’ is then used to fasten all the nuts to the proper torque.

The special, adjustable wheel gun reaction arm allows for safe and quick tightening and removal of wheel bolts. A reaction arm or back-up wrench is not required when this tool is combined with HYTORC Washer or HYTORC NUT.

Extra heavy duty air motor

The jGUN NUTRUNNER is equipped with a heavy duty air motor, allowing it to reach speeds of up to 210 RPM with a torque of up to 700 Nm in ‘run-down’ mode. This makes the loosening of corroded bolts child’s play.

5% accuracy in torque

In contrast to impact wrenches where the bolt or nut is beaten in place by an anvil, the jGUN functions as a precision torque/tension tool. The jGUN makes use of a precision drive which provides a constant, calibrated force and is capable of fastening the bolt to the required pretensioning force, time and again.

Twin torque: High Speed ​​Run-down mode and Torque mode

The jGUN Dual Speed provides the best of both worlds: the speed of an impact wrench, but without the high noise levels, vibration and variation in bolt force. The ‘twin-torque’ system has a first phase (rundown mode) for quick turning of the nut to the surface. The second phase (torque mode) is used to tighten all the nuts to the correct torque. Because the jGUN does not use the common ‘anvil’ to fix nuts in place, noise and vibration levels are significantly lower.

Safety paddle jgun

Versatility

With its generic spline teeth and drive square the jGUN allows for a wide range of (safety) reaction arms and (universal) nut drives to be fitted. You can even operate entirely without a reaction arm in combination with the HYTORC WASHER or HYTORC NUT. This improves safety, speed and accuracy. You can easily convert your jGUN into a ratchet link in combination with our offset link, which provides you with optimum freedom!

Use as a ratchet link

The universal spline teeth make the jGUN models suitable for use with the offset link. This allows you to turn your jGUN instantly into a ratchet link, which is suitable for situations where space above the nut is limited, or for situations with piercing thread ends.

Optional extra: safety lever

With the optional safety lever the risk of finger entrapment is drastically reduced. The lever must be pressed simultaneously with the trigger to ensure that the operator does not have his/her hands in the vicinity of the reaction arm.

Easy switching between loose and tight

Switching from loosening to tighten and vice versa is very easy to do: simply switch the shift lever. The lever is designed for easy operation, even while wearing gloves.

Maximum noise reduction

By default the noise level of the jGUN is already lower than similar models in the market, but the jGUN is expandable with an optional silencer. This allows for a silencer directly on the jGUN, but it is even more silent to work with a return hose. The outgoing air flow is then directed back to the air supply unit, where sound is reduced by about 75% through a large filter.
