When the tow and FUM-tape is not needed? Master OK
Greetings, your guests and subscribers! At this time, short of ways to seal threaded connections. Not everyone is ready to accept the fact that in some cases to use a sealing material on the optional connections. or rather, optionally use two seals to form a compound.
Many people think that if the thread in front of them, then seal on it to be sure, wound, plaster, wind the... And it's not bad, but not always necessary.
If, for example, we have a flexible hose as in the picture above, it already has the seal, however in the case of winding it on a tap or coupling with an external thread (RLV) of the other seal simply not needed, because of the seal 100% here corresponds to only a rubber ring and no linen hemp or FUM tape is no longer needed. Even if the wind is something on this thread and the rubber ring is clamped with bad or damaged due to the drag, the water will still only through the upper part of the nut.
Where the setting of rubber, plastic or silicone sealant in the form of rings, other sealing materials such as ribbons, threads, lubricants, fibers can not be applied.
In the photo above the hose screwed to the thread of the tap until it stops. The tube tap abuts against the sealing ring and overlaps guaranteed water is not only strongly tighten the nut of the hose not to cut the rubber ring.
Here's another example, when FUM tape is not useful. In the shown in the photo tap with an external and internal thread is a single compound without tape seal, and the other with him. Yes, on the part of the flexible hose is possible to wind the nut as it is, but from the MPH have podmotat fumku, because here it is the only way to stop the leak.
I do not need tape and linen when you are working with couplings with collar nuts (MOG), which is also used by the O-rings. The same applies to the installation of the mixer for the bath and shower on the already exposed eccentrics.
In other words, where there is a ring belt and the fibrous seal does not help, but if to put them or what system it will not hurt, just spend the material, and perhaps will calm themselves. Like this!
