The efficiency and safety of central heating systems and hot and cold utility water depend on the quality of the components used in them. That is why Purmo engineers placed emphasis on the durability and compatibility of elements such as pipes, connectors and tools. The CLEVERFIT Radial system created in this way is resistant to stress, extreme temperatures and pressure, as well as unfavourable physical and chemical parameters of water. And these are just some of its advantages. Get to know it better!

From this text you will learn:
- what are the characteristics of water pipes in the Purmo CLEVERFIT Radial system,
- what tools are included in the Purmo CLEVERFIT Radial system,
- what pipe connectors are worth using in the Purmo CLEVERFIT Radial system.
What are the characteristics of water pipes in the Purmo CLEVERFIT Radial system?
Pipes for central heating and domestic hot water installations in the Purmo CLEVERFIT Radial system are made of high-quality PE-RT plastic. Its use translates into absolute neutrality for the transported medium. In this case, this means that the pipes do not affect the composition, smell or taste of water. This is of course of particular importance in the case of domestic water installations.
Purmo CLEVERFIT Radial plastic pipes have been approved for use in water installations, and this is confirmed by numerous certificates. The manufacturer can boast, among others, a PZH hygiene certificate or a DVGW certificate. What's more, provided that the correct installation is carried out, the Purmo system has properties that reduce water stagnation in the installation. As a result, it delivers completely fresh water to every collection point in the building.
The Purmo CLEVERFIT Radial system uses multilayer pipes that combine the advantages of plastic and metal pipes. The PE-RT/AL/PE-RT models have an aluminum insert, are chemically neutral, and resistant to corrosion or fouling. They are therefore perfect for various installations - both heating and cold, hot or drinking water. PE-X pipes, in turn, are made of electron-beam cross-linked polyethylene with a built-in anti-diffusion barrier. Thanks to this cross-linking technology (unlike chemical technologies), the pipes are fully hygienic and neutral for drinking water.

What tools are included in the Purmo CLEVERFIT Radial system?
To perform the Purmo CLEVERFIT Radial installation, tools designed for professional assembly of the pipe system are necessary. To ensure maximum compatibility of all elements, the Purmo brand supplies the market not only pipes and fittings, but also crimpers, jaws and calibrators . They guarantee flawless assembly and failure-free operation of the entire system. All tools have been designed with easy operation, durability and reliability in mind.
The Purmo CLEVERFIT Radial system includes both electric tools (wired and battery-powered) and functional accessories. Among the former, we can distinguish professional equipment for crimping and pressing connectors, and among the latter - among others, scissors, calibrators or springs for bending pipes. Thanks to such a comprehensive offer, the installation of the Purmo CLEVERFIT Radial system is completely trouble-free, and all its elements fit together perfectly.
Fittings in the Purmo CLEVERFIT Radial installation

Purmo CLEVERFIT Radial plastic fittings have similar advantages to pipes. They are made of polyphenylsulfone, which is resistant to stress, high temperature and contact with aggressive and corrosive water. They are therefore perfect for buildings equipped with their own water intake with an additional treatment station. They are also intended for installation in facilities using rainwater for domestic purposes.
PPSU plastic connectors are also characterized by numerous technological conveniences - such as leakage control (LBP) and 2 pressing profiles (Multi Tool). The LBP function protects the contractor from the costly consequences of flooding the building due to a leak. An unpressed connection indicates a water leak at a test pressure above 1 bar. The Multi Tool function allows the connection to be made with TH and U profile jaws. This makes the system more versatile and does not require the contractor to change tools.

What fittings should I use to connect Purmo CLEVERFIT Radial pipes?
The wide range of Purmo brand allows you to make any pipe connection in the central heating system and other water systems. A versatile series of functional fittings with different geometries and diameters from 16 to 32 mm is used for this purpose. The design and equipment of the connectors provide many improvements. A special plastic ring facilitates positioning of the TH profile jaw on the connector. The inspection window allows you to check the correct position of the pipe in the connector, which is visible after full insertion. The stainless steel collar permanently crimps the pipe on the connector nozzle after pressing with the jaw, creating an inseparable connection. 2 O-ring seals made of EPDM rubber are hidden in the connector nozzle and protected against damage during pipe insertion. In addition, 2 seals provide a greater guarantee of tightness and durability of the connection.
