The reliable push sleeve system
One for all
TECEflex is a plastic pipe installation system with extensive opportunities for use in housing technology. The red brass fittings are certified and approved for use with potable water, heating, gas and compressed air. The special construction of the TECEflex composite pipes also enables universal use The only exception is the yellow outer layer for the gas pipe. TECEflex is therefore a truly universally useable installation system.
For 25 years, millions of reliable pipe connections have been created for drinking water, heating, gas and compressed air with TECEflex. For me, that means consistent quality.
TECEflex – reliable connections for 25 years
For 25 years, millions of pipe connections worldwide have been pressed with TECEflex, all using the same unchanged principle of axial pressing: The pipe is expanded and pushed over the fitting – the pressure sleeve secures everything. Nothing has changed in this underlying technology since the market launch of TECEflex. The scope of performance alone has been expanded through constant additions to the range.
Thus TECEflex became one of the few truly universal plastic installation systems on the market with the introduction of the large pipe dimensions up to 63 mm and the approvals for gas. Where necessary, the system has been adjusted to match new standards and requirements of law so that TECEflex is state of the art when it comes to safety.
TECEflex Application options
The TECEflex was accredited for its hygienic suitability for use with potable water with the DVGW approval and its long lifespan of at least 50 years was confirmed. A plus for the O-ring-free axial pressing technology: The connections are seamless and unhygienic stagnant water can't form anywhere.
The fitting materials used are approved throughout Europe.
TECEflex is suitable for all potable water installations.
Whether the radiator is connected from the wall or from the floor, the TECEflex range offers a solution for every application scenario. Combined with the junction fittings, radiators can be installed efficiently.
The white composite pipes look good mounted or in manifold installations. Remnants or offcuts can be used in other trades, e.g. potable water installation.
TECEflex is DIN CERTCO certified for heating installations.
TECEflex lets you create compressed air installations up to dimension 63 mm. Plastic pipes have the advantage over metal pipes that compressed air supplies in operations can be quickly adjusted to new demands.
The TECEflex is suitable for compressed air with these parameters
- Nominal pressure 16 bar
- Operating pressure 12 bar
- Maximum peak operating temperature 60° C
- Safety factor 1.3
Here the user handles the same TECEflex fittings and the same composite pipe as they do for the heating and potable water installation.
The O-ring-free connection technology means there is no restriction of the compressor oil used. TECEflex is thus an economical alternative to copper and steel.
With the appearance of the TRGE 2008, TECEflex can also be used in interior gas installations:
- Relocation of complete home gas installations up to 100 mbar
- TECEflex composite pipe in yellow signal colour
- same metal fittings as for potable water, heating and compressed air installations, so no risk of confusion.
The gas lines can be laid without fitting from the roll through the shafts and cavities without the need for these to be ventilated. This makes TECEflex particularly interesting for the connection of attic heating centres and the simplified design support from TECE makes planning easier.
So that cold water remains hygienically cool
When installing bathroom fittings the TECEflex Hygiene Box automatically meets the required standards for drinking water.
The TECEflex Hygiene Box thermally decouples the hot water circulation line from the fitting connection, and therefore reliably prevents heat from being transferred via the fittings to the cold water side.
Made from prefabricated components, it prevents the cold water from being heated above the permissible 25 °C.
The thermal decoupling of fittings and circulation lines is an important requirement for optimal drinking water hygiene. For me that means one less thing to worry about on site.
Using the Hygiene Box, cold water will remain cold
To develop the Hygiene Box, TECE looked at installation variants where the circulation lines run above the tap connection at a fixed distance. The warm water is supplied by a short stub line running vertically downwards.
This is designed to ensure stable stratification, resulting in thermal decoupling of the hot water pipe and the tap connection. Therefore heat transfer no longer occurs in the tap. In the past circulation lines often led all the way up to the tap to avoid stagnation in the stub lines. However, this led to an inadmissible heating of the fittings and the cold water side.
A long stub line will reduce heat exchange but bears the risk of stagnation.
The TECEflex Hygiene Box provides a simple and effective solution.
Thermally decoupled cold water side
The ready-to-connect Hygiene Box produced by TECE as a result of optimising the process, provides a practical solution to the problem. It guides the warm water pipe above the warm water wall disk. In this short, vertical connection piece between the wall disk and the circulation line, stable thermal stratification is created, resulting in thermal decoupling of the warm water pipe and the tap connection. This prevents unreliable heating of the cold water side, so the fitter won't get any complaints.
The insulated, ready-to-connect TECE Hygiene Box is available by itself for the warm water connection, as an assembly unit with a double wall disk for the cold water connection, and as a sanitary module for the TECEprofil dry-wall system.
Advantages for designers and contractors
- Drinking water regulations are automatically met - cold water stays cold.
- Prefabricated components ensure efficient assembly and reliable, safe performance.
- Insulation shells make it easier to connect the pipe insulation.
- High compatibility with different pipe adapters.
- Offers designers and contractors protection from cost-intensive complaints.
The TECE Hygiene Box enables quick and easy thermal decoupling of the cold water.

The TECEflex pipes are permanently connected to the fittings using axial pressing technology. Only the pipe plastic is used as a seal. No additional aids such as O-rings or sealing tapes are required. The O-ring-free connection technology is very error-tolerant and especially hygienic.
To create a TECEflex technology, first the pipe must be expanded. The fitting is pushed into the prepared pipe and the sleeve is slid over the expanded pipe up to the fitting collar.
The TECEflex composite pipes are equipped with an electron beam networked PE-Xc internal pipe. The PE-Xc plastic is characterised by a particularly strong memory effect. This has the effect that the material of the expanded pipe shrinks back over the fitting nozzle. The pressure sleeve additionally secures this connection.
The advantages of the TECEflex connection technology at a glance
- error-tolerant O-ring-free connection technology
- specially hygienic connection since there are no gaps for water to stagnate in
- low pressure losses as the internal diameter of the fitting and pipe are almost the same
- the axial pressing technology comes with zero requirements for maintenance of the pressing technology Sleeve at the front - connection tight
TECEflex offer an extensive range of red brass fittings. The red brass fittings can be used for potable water, heating, gas and compressed air. The fittings come from a red brass material unconditionally recommended by the German Environment Agency (UBA) and recognised across Europe that is suitable for all levels of water quality according to the current drinking water regulations.
Alternatively to the red brass series, the range offers an array of low-cost plastic fittings made of high-performance plastic PPSU. The PPSU fittings can be used for potable water, heating and compressed air installations. These are not approved for use in gas installations.
Advantages of the TECEflex fittings at a glance
- the red brass fittings are universally approved for any application
- the fittings are suitable for all quality levels of potable water
- the fittings are made of either pure red brass or pure PPSU. They are not coated or installed. Simple technology - fewer mistakes
The tradesman has the choice between PPSU and red brass fittings.
TECEflex pipe system variants
The TECEflex composite pipe is equally suitable for potable water, heating, underfloor heating and compressed air installations. The pipe for gas installation differs only by the yellow signal colour. Owing to its special construction, this universal pipe has high safety reserves and remains round and burr-free when cut to length. The medium-associated inner pipe consists of a PE-Xc basic standard pipe.
This permits high pressure, temperature and corrosion resistance. The additional butt-welded aluminium sheathing serves both as a diffusion block and to reduce longitudinal deformation caused by heat.
The TECEflex composite pipe is particularly easy to bend by hand, yet retains its rigidity. The outer white layer means that there are no problems installing it in visible locations, e.g. to connect radiators.
- Dimensions from 14 - 63 mm
- as rolls or in rod form
- in black corrugated pipe sheathing or
- pre-insulated variants
Advantages of TECEflex composite pipe
- universal pipe for five applications
- length extension comparable to copper pipe
- visually appealing outer white layer
- easy to lay because of its bend-resistant rigidity
- corrosion resistant
- resistant to heating inhibitors
- external and internal monitoring
- outstanding creep strength
With the TECEflex PE-Xc 5-layer plastic pipe, the fitter has a low-cost pipe for potable water, heating and compressed air installations.
The new 5-layer technology of the TECEflex PE-Xc 5S pipe also offers an additional advantage: Placement of the oxygen barrier layer in the centre of the pipe wall. This is thus optimally protected against damage.
- same fittings as with the TECEflex composite pipe
- inner pipe suitable for potable water
- oxygen-proof for heating installations
- suitable for compressed air installations
The PE-MDXc has been specially designed for underfloor heating. It's particularly light and lays free of twists but the cross-linking and the 5-layer technology make it especially robust and temperature-stable. It can even be used to connect radiators.
The new 5-layer technology allows placement of the oxygen barrier layer in the centre of the pipe wall. This is thus optimally protected against damage.
The three-pipes-one-fitting strategy:
Naturally, the same fittings can be used not only with the composite pipe, but also with the TECEflex 5-layer plastic pipes too. This reduces storage costs and at the same time offers flexible opportunities for assembly on site.
