How to choose the right hose clamp installation tool?

The hose clamps is equipped with professional hose clamp pliers, especially ear clamps that require tools to be clamped. The clamping effect is affected by the pliers. Only by using the correct method to clamp, can the clamp not be damaged by the clamp, and can effectively tighten. Choosing the right tool and the right method can reduce a lot of disputes caused by the use of clamps in daily life, whether it is a hose clamps quality problem or a tool problem.

There are many pliers in the market that look the same. In fact, after using them, you will know that some pliers are very similar to professional hose clamp pliers. They are similar in appearance, size, and function, which can easily mislead consumers. Moreover, the price of this kind of pliers is relatively low and cheap, because of the occasion of use, the workmanship and material of the pliers are not high. The clamp is easy to be damaged.

Ear clip pliers


For example, this type of pliers, the pliers head is too small, is also more common in the market. The main problem with this type of pliers is that the jaws are too thick and the middle cavity is too small. During use, the jaws cannot go deep into the root of the ear clip, and cannot provide sufficient space for the ear of the laryngeal hoop, resulting in deformation of the ear, and the clamping effect cannot reach the expected effect. Especially for small ear clips, the jaws are too thick to form an inverted triangle ("") shape at all but will form an inverted V-shaped ("Λ") ear, this is completely unable to play a fastening role.

Choosing the right ear clip pliers

The jaws should be thinner and sharper, with a larger middle position. The clamping process can go deep to the root of the ear clip ear, clamping to form a symmetrical triangular ear. Use the right tool to clamp the hose clamps regardless of size, the ear shape is very beautiful, and the jaws can go deep into the root of the ear. At the same time, because the inner cavity of the ear hose clamp pliers has enough space, it can effectively avoid both sides of the ear hose clamp. Will not damage the hose clamp.

Slotted screwdriver

For example, hose clamps of the worm gear hose clamps type are generally flat-blade screws and Phillips screws, both of which can be fastened with a flat-blade screwdriver. Most of these screws are hexagonal in shape, and hexagonal screw clamps can also be used.

The choice of the flat-blade screwdriver is generally not too demanding. A normal screwdriver can unscrew all the flat-blade screws.

Hex screwdriver

Hexagonal screws are divided into hexagon socket screws and outer hexagonal screws. The outer hexagon can use a screw socket, and the hexagon socket screws can use an inner hexagon screwdriver. Determine the diameter of the screw and select the corresponding screwdriver or screw socket wrench to tighten it. If the outside of the screw is not round, it can be clamped and tightened directly with pliers.

When choosing a hose clamp, you should consider the quality of the screw head of the hose clamp. If the quality of the screw head of the hose clamp is not high and the material used is poor, there may be a slipped screw head, especially when you need a larger tightening force. At this time, it is necessary to tighten the hose clamp vigorously. When you need to remove a damaged hose clamp, you often cannot use tools to turn the screws. Therefore, when choosing a hose clamp, you should pay attention to whether the material of its accessories is the same as that of the hose clamp belt, so as to avoid some businesses from using screws of poor material on the accessories.


Magnetic screwdriver tools: When screwing the screw, you can choose a tool with a Magnetic, or you can use a magnet to magnetize the tool. The tool has a certain degree of magnetism, when the screw is screwed out, it can have a little attraction to the screw, reducing the probability of the screw falling.

How to unscrew the hexagon socket screws with only a slotted screwdriver?

Use the longest diagonal of the hexagonal diagonal to insert a flat-blade screwdriver. If the screwdriver keeps slipping at the screw head, you have to find a way to increase friction or torque. You can insert a steel nail upside down to padded something to make it easier to get stuck. If the width of the screwdriver is not enough, wrap the screwdriver a few times with tape or something.

If you have an electric grinder or a hacksaw, you can cut a groove, and a flat-blade screwdriver can easily unscrew the hexagonal screws. In the process of unloading, the screw is very tight and the screw can be heated, and then tap the screw lightly. When the screw is tightened, use the screwdriver to rotate the screw downward, which can have a beneficial effect on the screw off.

The above are all manual installation tools. Manual clamps are only suitable for small batch installation of clamps. If it is a mass installation, we recommend the use of pneumatic installation tools. Pneumatic wrenches, pneumatic screwdrivers, and pneumatic clamps are widely used in installation scenarios in various industries, greatly improving the efficiency of the installation.

Pneumatic clamp plier

There are many types of pneumatic clamps plier, and a very important point is the controllability of pneumatic clamps. 

Any fastener installation will have a degree. It is just enough to satisfy the use within this degree. If the degree of screwing is not enough, or too much. The clamp will not be tight, or the fastener will be damaged. It's basically because the working force value of pneumatic tools comes from air pressure. The instability of air pressure is a major factor causing uncontrollable. 

Pneumatic clamp plier

The pneumatic clamp plier is convenient, easy, and fast. For hose clamps with higher installation requirements, please note that there should be a force value instrument for clamping, which can be used only when the instant clamping force is monitored. For example, the needle barometer, the SAE standard of the standard manual for clamp fasteners, and the GB standard of the screw carry out the corresponding conversion of the operating parameters.

Before installing the clamp, get the standard manual of the hose clamp to be installed, and find the clamp installation clamping force of the corresponding specification. Before using the pneumatic clamp pliers, calibrate the pressure of the tool to reach the clamping force required by the manual. Check the force value instrument data on the pneumatic clamp pliers pipeline for verification. After the force value has reached the clamping force value required by the manual, proceed to work. Finally, use the pneumatic clamp plier that has completed the previous steps to clamp the clamp. The installation is complete.


It is not necessary to pass the above procedure for each clamp. The above is the calibration process. Periodic calibration can be performed on batches or days. To ensure the consistency of the installation effect.
