How to properly wrap threads with flax?

The most important thing in this matter is not to overdo it - if you wind too much flax, the resulting connection may burst, if you wind too little flax, it may leak. It is necessary to maintain a golden mean; all this comes with practical experience.

How to use sealing paste correctly - how to use Unipak?

Manufacturers recommend spreading the paste onto a pre-cleaned thread, then winding flax on top, spreading another layer of unipak on top. It can be done simpler without compromising the quality of the connection. For example, either spread flax only on top, or dip the entire strand in sealing paste - the effect will be the same.

The flax should be screwed onto the threaded connection in a clockwise direction so that it does not unwind when screwing the parts. After the flax has been wound and sealing paste has been smeared on it, the connection must be carefully tightened together with two keys and proceed to the next stage of work.

How to wind the thread?

To seal the joints, you can use your choice of flax and plumbing paste. In this case, it is necessary to keep in mind that flax is not suitable for pipelines designed for operation at temperatures above 90 degrees, because it burns out over time, losing its properties. You can use TANGIT Uni-Lock thread or its equivalent. The blister packaging confidently states that 20 meters is enough to seal 50 connections for 1/2-inch threads. The analogue - "Plumbing" at the same cost has 50 meters and is sold in almost any store like Leroy-Merlin.

You can use polyamide thread in combination with silicone lubricant. The branded TANGIT Uni-Lock consists of polyamide thread and silicone, so you can easily save money by taking a regular thick polyamide thread and silicone or plumbing grease at any hardware store.

Tangit uni lock - a revolutionary thread

Linen, jute rope or a similar analogue made from plant materials can be purchased on occasion at a hardware store, spending about the same amount for the same 50 meters.

When using silicone sealant, you must keep in mind that it hardens quite quickly, so after a short period of time it will no longer be possible to adjust the connection; such sealant will simply break inside the thread. For these reasons, the sealing filler should neither harden nor wash out.

Another interesting point is that acetic-based silicone sealants cause metal corrosion; this must be taken into account when choosing materials.

The easiest way to decide what is suitable for sealing and what is not is to experiment first.

How to wind?

For professionals, this is a matter of habit - some wind it crosswise, some strictly follow the instructions detailed in the instructions, and the most important thing is that you need to wind it tightly, so that the thread is completely covered with the material used, in which case nothing will leak. However, the thread wound against the thread may be damaged when tightening the nut.

To wind flax, you need to separate a small strand the thickness of one or two matches, smooth it out, select and discard small fibers. You can twist the strand into a cord. Then wind it very tightly along the thread, starting from the edge of the thread, so that the thread groove is completely closed. After this, you will need to take the plumbing paste and spread it onto the linen with rotational movements. If everything was done carefully during the work, then everything will definitely work out. All that remains is to tighten the connection using a little force. If the nut tightens easily, it means that either a small amount of flax was wound, or there was too much gap between the internal and external threads. Everything will need to be disassembled and rebuilt again. If the work was done correctly, the flax will not stick out, and you will get a reliable and airtight connection.

Simply wind the TANGIT Uni-Lock thread crosswise or wind it along the thread 6-8 turns and connect the parts together - the work will be completed.

In the homemade version, the polyamide thread must be wound and coated with plumbing paste or silicone grease. You can pre-impregnate the entire skein of polyamide thread with silicone grease, then wind it around the joint and connect the parts. The soaked skein can then be placed in plastic packaging so that it does not stain anything, does not dry out, and nothing unnecessary sticks to it.

For work, the linen rope needs to be separated into two cords, cut off 40-50 cm from it, wound around the thread, lubricated with plumbing paste and tighten the resulting connection. It is possible to understand what is better to use in the process - a synthetic thread - TANGIT Uni-Lock or another analogue - only if you have the appropriate experience.

Common name TANGIT UNI LOCK- differs in smaller packaging.

1. Clean the thread and roughen it if necessary.
2. Starting at the end of the pipe, wrap Loctite 55 onto the pipe threads in the same direction as the helix thread. For best results, do not place sealing thread directly into the thread groove. Wind the cord around the thread and try to tighten it.
3. Cut the required length of thread using the knife built into the dispenser. Smooth the free end into the threads.
4. Attach the female thread fitting.
5. Tighten with a wrench until it stops. If necessary, the assembled units can be adjusted.

Recommended amount of thread depending on thread diameter (metal)

*The number of threads may vary for threads not conforming to DIN 2999-1 or ISO 7/1.
Plastic pipe threads require at least twice as much material as recommended for metal threads.

Before applying the product, degrease, clean and dry the surfaces of the parts - what the product can be used for Loctite 7063 (150 mlor400 ml).
It is not recommended to use activators and cleaners from third-party manufacturers, becausetheir chemistry may not be compatible with Loctite anaerobic products

Loctite Liquid Threadlocker Average Consumption Chart

In practice, when filling threaded gaps of 0.1 mm (in M3-M10 threads) and 0.2 mm (in M20-M30 threads), the product consumption increases by 20% of the above.

The above table provides information on the estimated consumption of Loctite thread sealants for various applications. The practical consumption of Loctite thread sealants will depend on the actual gap in the connection, differences in viscosity due to temperature changes, as well as certain product losses during the technological process. Taking into account the above, in order to normalize product consumption during the production process, it is recommended to carry out preliminary test assemblies.

And so, if you need to connect two plumbing parts so that the connection does not leak,

this can be done using all sorts of different tapes

Or using flax. Many may accuse me of not modernizing the thread seal - flax.
But I still seal it with flax because it’s cheaper. I rarely use this kind of tape; I use it where linen won’t help, but more on that another time.

In addition to flax, I use unipack and multipack.

This is a kind of sealing paste. It serves to ensure that the flax does not deteriorate, does not burn due to temperature, and the connection can be disassembled. Because earlier this same flax was smeared with paint. After the “dyed” flax has been standing for a year, it is difficult to disassemble such a connection. If the flax is not smeared with anything, the connection will be short-lived.

Moreover, the use of paste allows you to adjust the connection. Those. if you twist it a little, then according to the manufacturer, the connection can be twisted back up to 45 degrees.

Now flax.

Linen is sold in different ways. The most convenient way for the user to pack flax is in skeins like threads

A ready-made strand is taken from the middle. This is a great solution, but not very cheap.
That's why we use it in a different form. But they also differ in quality. In the first photo we see shit-linen and in the second - linen. Shit-flax differs from flax in that the former is very coarse and can be smelly. It is more difficult to make a strand of the desired “thickness” from it.

How to wind?

everything is very simple. The main thing is not to be afraid and not to overdo it. The bottom line is this: If you wind too much, the connection may burst; if you wind too little, it may leak.
How to use Unipack? The manufacturer recommends spreading the paste onto the cleaned threads, then wrapping flax and adding another layer of uniatka on top.
We smear only on top, and sometimes I just smear the entire strand with unipak and then wrap it around the thread.

The most important thing is that you need to wind the flax so that when twisting it does not unwind. On a regular thread, wind it clockwise. When twisting the product, the linen will not unravel. And so, let's go:

Did you reel it in and apply a unipak? Now let's twist it.

The most important thing is not to wrap too much so that the fitting does not crack.
This connection must be carefully tightened with two keys. And we can end here. Let's move on to the next connection.

Addition of material from comments from reader Ilya. October 2012

To seal connections you need to use your choice:

1. Linen + sanitary paste.
Linen is not suitable for temperatures above 90 degrees; over time, it boils, burns, and loses its properties.

2. TANGIT Uni-Lock or equivalent.
Tangit Uniloka is more expensive than its analogues, 20 meters of Tangit Uniloka (packaging on a blister on which it is written that it is enough for 50 connections for a 1/2-inch thread) costs 130 rubles, and the analogue - “Plumbing” 50 meters costs the same 130 rubles ( in Leroy-Merlin, St. Petersburg).

3. Polyamide thread + silicone lubricant.
On the packaging of Tangit Unilock and its analogues the composition is written: polyamide thread + silicone. If we want to save money, we conclude: you can buy regular thick polyamide thread at a hardware store or a sewing store and buy thick or liquid silicone grease from auto parts or the same plumbing paste.

4. Linen rope + plumbing paste.
Construction and hardware stores sell household linen, jute and similar ropes made from plant materials. They cost about 50 rubles. for 50 meters.

Silicone sealant is not suitable because it polymerizes/hardens and if you need to position the connection, say, after a few hours, it will be torn inside the thread. Therefore, it is necessary to use a non-hardening and non-washable sealing filler. Additionally, vinegar-based silicone sealants can be corrosive to metals.

In general, in order to understand what is better, you just need to experiment.

How to wind? Crosswise, as indicated in the instructions for Tangit unilok, either with or against the thread - it’s all a matter of habit. The main thing is to wind it tightly so that the thread is covered with the material used. I can wind it this way and that way, and nothing will come out of the thread or leak. But still, thread or flax wound against the thread will be cut faster when tightening the nut, this is obvious.

Winding different materials for 1/2" thread:

1. We take flax, smooth it, cut off a strand one, or maximum two, matches thick.
We smooth the separated strand again, holding it between our fingers, and throw away the small fibers.
If desired, you can twist the strand into a lace.
We wind it very tightly along the thread, starting from the edge so that the thread groove is completely closed.
Then we take the plumbing paste and spread a small amount with rotational movements onto the wound flax.
If your hands grow from the right place, then everything should work out very neatly.
Then we tighten the connection, twisting should occur with a certain force, but not with all the dope!
If the nut tightens easily, it means there is not enough flax, or there is too much gap between the internal and external threads. You need to unwind the flax and wind more new one.
If everything is done correctly, then the linen should not come out from under the thread and it will be dry :)

2. We wind the Tangit unilock thread along the thread or crosswise 6-8 turns and connect it. And that's it.

3. Homemade option. We also wind the polyamide thread and coat it with plumbing paste or thick silicone grease. Or first soak the entire skein of thread with liquid silicone lubricant. We wind on the connection. Let's connect. That's all.
If you soak or soak a skein of thread in liquid lubricant, then you need to put it in some small plastic box or bottle so that dirt does not stick to the thread and it does not stain anything.

4. We separate the linen rope into two laces from which it is twisted. We cut off 40-50 cm. We wind it onto the thread. Lubricate with plumbing paste and tighten the connection.

Synthetic thread - Tangit Unilock or an analogue - is the most universal!

True knowledge will come only with experience!
