At present, the market of fittings for heating
and water systems is very diverse. In addition to the most popular
polypropylene systems, there are many fittings for cross-linked polyethylene
pipes. Pex fittings, press fittings, push and axial fittings. The latter form
is becoming more popular from year to year. In this article, you will see what
the Ukrainian market offers in this category of fittings.

| Pict.1 Axial fittings |
The given system has several names - a system
of tension fittings, with a sliding sleeve, a system of axial fittings, etc.
Here are some facts contributing to its popularity:
- reliability of connection;
- speed and ease of installation;
- foolproof (it is almost impossible to make a
connection incorrectly);
- eco-friendly
materials.
Now let's see what brands are on the market.
REHAU

The unconditional leader among the axial
fittings is the Rehau Rautitan system. The German concern has been releasing
this product for a long time. Moreover, he went from an unfamiliar and new
product, to the leader to whom they are equal. The fittings are made of two
materials - brass and plastic PPSU. The main element, sliding sleeve is made of
PVDF or brass.
The system includes pipes made of cross-linked
polyethylene PEX-a, which have become a kind of standard in the heating world.
The assortment of pipelines starts with a size of 16 * 2.2 and ends with a pipe
of 63 * 8.6mm. Pay attention to the thickness of the wall. It is larger than
that of standard polyethylene or multilayer pipes (16 * 2.0 mm).
Buying the Rehau Rautitan system, you can be
100% sure of the quality.
TECE

Another brand from Germany TECE sells its own
system with a sliding sleeve - TECEflex.
She is very close to Rehau. Diameters, type of fitting,
etc. The assortment also represented by polymer and brass fittings in the range
of sizes from 16 to 63 mm.
Pipes are made of polyethylene PE-Xc.
The company's products correspond to many
European standards, including the German one - DVGW.
KAN-Therm

| Pict.4 Push Platinum system of KAN-Therm |
The Polish giant KAN-Therm has in its lineup
many pipe systems. In addition, one of them is KAN-therm Push.
Poles went on a different path. They produce
pipes and fittings of this system in other sizes than the Germans. The ruler of
the sizes - 14х2, 18х2,5, 25х3,5, 35х4,4 mm. This means that if you want to connect, for example, two Rehau
and KAN systems, it will be extremely difficult and inconvenient.
As in the case of TECE, pipes for KAN-therm
Push consist of a PEX-c material.
UPONOR

| Pict.5 Uponor axial fittings |
Uponor, a Finnish company, implements the
Uponor Quick & Easy system (Q & E) in Ukraine.
To create a
connection for all previous systems, you need two tools - a pipe expander and a
"tensioner" of the sleeve. The joining process consists of three
stages - expansion of the pipe, insertion of the fitting and liner liner.
Uponor further simplified this. To create a connection in the Q & E system,
you only need to expand the tube with a polyethylene sleeve on it and put it on
the pipe. And the connection is ready!
Quickly and simply - the whole point of the
Uponor Q & E system lies in its name.
The
diameter range is from 16 to 75mm. Pipes - RE-Xa.
GIACOMINI

| Pict.6 Giacomini GX |
Italians from Maurizio d'Opaglio represent
a similar Uponor system
Giacomini GX. It also uses a polyethylene
tension ring and only one expander.
But unlike the Finns, in the range of only
fittings made of brass. Dimensions - 16, 20, 25, 32 and 40 mm.
One of the drawbacks is the use of PEX-b pipes.
I think that this is due to the desire to reduce the price of the system as a
whole.
This system sold in Ukraine for less than two
years. But I think that its popularity will grow.
GENERAL FITTINGS

As in the case of the Italian colleagues, the
axial fittings from General fittings are a relatively new product in the
Ukrainian market.
In the range of only brass fittings and pipes
made of PEX-A This system is analogous to the Rehau Rautitan system.
HeatPEX

| Pict.8 Heat Pex sysytem |
The Ukrainian brand HeatPex can be singled out
separately. Brass fittings manufactured in Ukraine, and PEX pipes imports from
Israel. They are manufacture at the facilities of the Golan concern.
Due to
affordable prices, the popularity of the brand has grown lately.
FADO
The product FADO Slice appeared a couple of
years ago. It also finds his customers. The fitting is made of brass. The PEX
pipe is produced in Spain.
ALFA CHE
Another new brand. Also designed for the type
Rehau, as well as FADO. Brass fitting, PEX-C pipe,
manufactured in Italy.
Here's the situation in the market of taxial
fittings. I think that the competition will grow. It will lead to even more
interesting offers. In addition, this is always interesting)
