Kinds of pressing tongs used for metal-plastic

The tool for metal-plastic and press of pipes are conventionally divided into two areas:

  1. Household press pliers for metal-plastic joints. Used for limited diameter connections.

    This device has a limited versatility, which manifests itself in meeting only the standard requirements. Suitable for some communications that provide heat supply and water supply.

    Not a big, but rather significant drawback of the hand press is its performance. Therefore, if you need to perform a large amount of work, this device can not cope.
  2. Professional Appliances. These include: press pliers and appliances with electric drive.

    Used due to crimp movements and the operator's force on the hydraulic press and electric drive. It enables you to perform a variety of workloads.

    Moreover, the performance conditions also allow the use of different types of nozzles. The market of sanitary ware includes various types of pipes and fittings of different volumes and grades.


    A significant disadvantage of these tools is their expensive cost. But this is not surprising, when the device itself is of high quality, it is also valuable.

How to press the pipes and fitting yourself?

Conditions required for pipe installation and tools for metal-plastic press fittings:

  1. We measure the pipe blank with a pipe cutter. The length of the segment must take into account the dimensional marking of the external surface of the product and a small calculation for the length of the length.
  2. The measuring part is also cut with special scissors so that the edge of the guillotine is turned parallel to the pipe, and presses it. In this way, an almost ideal cut is made with an angle of 90 ° to the axis of pipeline communications.
  3. The chamfer is then chamfered from the cut ends of the workpiece using a calibrator. It is important to put the crimp sleeve on the pipe from the fitting and insert it into the end of the workpiece.
  4. Before installing the pipe and fitting the fitting, it is put in a gasket, which provides extreme tightness and corrosion protection.
  5. To fix the immovability of the pipe in the sleeve, you can use the mounting ring.

Instructions for using

The first thing to do is to move the handles of the mites and put them on the table. Then they are disconnected from each other, and the lower part of the press-insert is placed in the lower part of the cage, and then snaps into place after the casing. A clip of pipes and fittings is fastened to the clip of mites, and a tool for metal-plastic is "launched".The sleeve of the fitting is already inside the insert and at that moment the keys are compressed until they stop.

Tool for metal-plastic - press of pipes and fittings Inserts are divided into the types on which the connection quality depends:

  1. Press fitting type OPS.It has a common fixing system, which makes the press process much easier.
  2. Press fitting type APC.The liner has a standard system for distributing the load to the sleeve.
  3. Press fitting type APS.The insert provides 100% success, since it is difficult to stop the process completely without crimping the sleeve.

Tool for metal-plastic - press of pipes and fittings Summing up the above, it is worth recalling that press jaws and inserts can not always cope with the task, but still remains the most sealed way to join joints. The main thing is that you should listen to the recommendations and then the result will not keep you waiting.
