1. Appointment of the pakli and how it works. 2. Types of sealing materials. 3. Method of sealing pipe thread with tow. In plumbing work, tow is used for sealing pipes and transitions connected by means of thread. It is made mainly of flax waste and is a coarse fiber of small size. If the tow is properly wound, leakage protection will be ensured throughout the life of the pipeline. Answering the question of how to wind the tow on the thread, it should be said that the quality of execution prevents the occurrence of the risk of a leak in the plumbing system. There is a gap between the threaded connections through which the water easily goes beyond the pipeline. If it contains properly laid plumbing plumbing, then the gap becomes smaller, and during the penetration of water into such a connection,

Varieties of sealing materials.

The main materials that create a sealed interlayer between the threaded joints are: - towel plumbing, - FUM tape - liquid FUM. Silicone is used as an additional material for the pakule, but in itself, due to its properties, can not provide reliable protection of the connection from leaks. FUM is a thread rewind consisting of made of Teflon tape, it is not wetted with water and creates a water-repellent layer in the joints. FUM is a one-component sealant of blue color, on contact with air it slowly solidifies and forms a strong enough and dense aggregate, which prevents the outflow of water from the system. But, if using the above listed materials, pressing the water pipe can be made immediately, then after using the liquid FUA, you need to wait a certain time before testing the system, depending on the diameter and ambient temperature.

The method of sealing the pipe thread of the stick. Quality thread rewinding is carried out with the use of the following materials and tools: - Tube lever keys in the number of two pieces -plumbing fixtures - FUM tapes.  How to wind the thread on the thread quality

The procedure for obtaining a quality hermetic screwed joint, consider the example of combining the union nut (American) with 1 inch male thread and non-return valve. From the tow we separate the strand with a length of approximately 5 to 7 revolutions of 1 inch diameter and the density indicated on the photo.

The resulting workpiece is applied to the beginning of the connecting element of an American, while its thread should be directed at you, and winding clockwise, along the coils and back. We bring the end of the tow to the beginning of the thread and with our fingers, clockwise, smooth it down. In the end, it should look like the photo.

Then, on this part we wind the FUM clockwise, so that it completely overlaps flax sanitary and lay down on him in 2 - 3 layers.
 How to wind the tow on the thread quality
Teflon tape does not allow the tow to turn and move down from the part. The American gains a check valve and, with the help of keys, we tighten them until a noticeable load occurs.
 How to wind a tow on a thread of quality
Such a combined thread winding , with appropriate skill, almost always ensures a reliable fit of two detachable elements of the pipeline. When all the components of the system are assembled, it is necessary to pressurize it at a pressure of approximately 1 bar and inspect all threaded connections for leaks. When using low-quality parts, the amount of winding should be slightly reduced, as in the process of flax swelling there are forces that can damage the part.
