Nut for the mixer - the main types and their features

Mixers

Mixing taps consist of a set of elements, each of which performs certain functions. That is why there can be no trifles in the system, and such a node as a nut is extremely important to ensure the operability of the entire structure as a whole.

In fact, in any modification of the crane there are several nuts, we will consider what they are and what functions they are intended for, because often during repair, problems arise precisely with the locking elements.

Recommendations for the selection of nuts

If you need to find the nut separately because of the loss or damage of the complete, then you should remember a few simple rules:

The best selection is based on the sample.	Of course, if you have an old item, then purchase a new one at times easier. It is enough to compare the two products and make sure that they have similar parameters and are interchangeable. But not always the sample is at hand, so you can take with you a mixer part that needs a fastener.
Examine quality	If there is no sample, then it is necessary to take measurements very carefully and carefully, and when choosing, choose the option that is made better: there are no burrs on the thread, it is knurled evenly and carefully, there are no spots and shells on the surface. Every little thing matters, as it can be used to judge how well an element is made.
Consider the type of crane coverage	Putting a bronze nut on the chrome-plated design, as well as vice versa, is not the best solution, as it looks not very attractive. Of course, this item does not apply to cases where the mount is hidden and it simply will not be visible, in this situation any color will do.

Tip! Another factor that testifies to the quality of the product is its mass. High-quality options weigh a lot more fragile elements from powder alloys, so it’s better to choose the ones that are heavier.

Types of products and basic installation guidelines

As noted above, various nuts may be present in the design, we consider the most common ones, since the number of models is enormous and atypical elements may be present in the design.

Kinds of nuts

Most often during installation and repair work one has to deal with the following nodes:

Fastening elements to the water supply system, they are located on the inlet highways and are usually in sight.. Most often they are rigidly fixed on the structure and it is impossible to replace them, it is necessary to purchase a new mixer. Therefore, when working should be careful and do not put too much effort to not break the element, also watch the position of the rubber gasket, it should stand straight.

It is not recommended to use the open-end wrench as it is possible to damage the coating, it is better to use flare fittings.

The nut to the faucet body under the spout serves to fix the gander of the faucet. Its main feature is that the spout should not only be well fixed, but also move left and right; for this, a plastic expanding washer must be present under the nut. Recommendations for fixing such knots are simple: you should not put too much effort, but rather twist the system carefully so as not to scratch the outer decorative coating.

For twisting on the element there are special protrusions

The clamping nut is also needed for systems installed on the sink or sink, it is located below and is not visible from the outside.. The price of these elements is small, but it is better to purchase a version of bronze or brass, so as not to worry about the fact that the node will be damaged by corrosion. You can clamp the system with your own hands without using the key, since too much effort is not required.

The clamp to the surface should be done through a rubber gasket

Another view is the nuts fixing the cartridge in the lever cranes.. They are hidden under a decorative ring and you can reach them only by removing the handle. The design has a large size, in the upper part are located the turnkey faces, and in the lower part there is a thread of a certain size.

Clamping elements - an important part of the design

Features of the work

The installation manual tells the assembly procedure, but how to disassemble the system, you will have to study it yourself.

Consider how to change the nut on the mixer, if it can not be unscrewed:

All items damaged by corrosion should be replaced with new ones.

The first thing to do is to gently hammer the connection on all sides, do not apply too much force in order not to damage the edges and the threaded connection.
Another option is to treat the structure with a liquid key, this compound dissolves plaque and makes unscrewing much easier. In particularly difficult cases, this operation can be repeated 2-3 times.
How to unscrew the sticky nut on the mixer, if the above methods did not have the desired effect? You can use a hair dryer and heat the connection, this method allows you to cope with even complex problems.

Tip! It is worth unscrewing the fasteners carefully, since it will be much harder to carry out work when the edges break down and you will have to make cuts on the structure.

Conclusion

Nuts are not the main element of the system, but their importance in the correct operation of the structure is difficult to overestimate. The video in this article will help to better understand this issue.
