- Corrugated tube made of stainless steel AISI 316L
- Temperature: as standard, delivered with fiber gaskets with limited temperature 110ºC. Gaskets for special applications at higher temperature rating are also available upon demand.
- Thermal insulation: elastomeric insulation foam is available upon demand in several thickness options.

As a result of its involvement in developing increasingly secure flexible connectors, polyester braided PEX hoses of TUCAI have obtained the DVGW certification based on the European Standard EN-13618.

We therefore recommend the use of our ACB (Anti-Corrosion Braid) range of hoses on those applications where this risk is higher, such as:

• High corrosion environments: public bathrooms or seaside housing.
• Applications where hoses are hidden and corrosion cannot be detected by the user.

The TAQ PEX ACB range has been designed to guarantee a longer lifespan in extreme conditions and the total respect of the consumer health. The Anti Corrosion braiding developed by our engineers guarantees a longer lifespan, even in harsh and corrosive atmosphere.

Polyester gives a high resistance of the braid to the corrosion when exposed to chlorine, which may damage stainless steel.

The ideal solution for hydronic heating and cooling systems.

Flexible connectors with oxygen barrier are the ideal solution for the installation of hydronic heating and cooling systems. Excessive oxygen entering the system can lead to premature failure of ferrous metal components due to corrosion and cause wide spread system failures. The oxygen barrier reduces drastically the amount of oxygen in the system, helping to prevent rust or corrosion in metal parts and avoiding the formation of biofilm and mud in the piping

system due to water deterioration. This is key to keep the efficiency and rated energy saving of the heating and cooling systems, and helps to minimize the related maintenance operations.

Oxygen diffusion resistance according to DIN 4726 Oxygen diffusion into the pipe system increases the potential for corrosion in metal components.

The oxygen barrier layer prevents oxygen to diffuse into fluids. It is integrated in the pipe by an extrusion process to ensure that oxygen cannot penetrate through the pipe wall over the time.

The introduction of oxygen into the system could contribute to the hot and cold pressurized water pipework deterioration. DIN 4726 has been specifically developed to evaluate the diffusion of oxygen into refrigeration and heating systems.

(*) A pipe with no oxygen diffusion barrier has an oxygen permeability of more than 2g/m3.

INSTALLATION BENEFITS

1. Provides huge cost savings to builders as installation time is reduced up to 40%.

2. Extremely light. Easy to handle on site.

3. Permanent leak-proof union.

4. The assembly by means of simple push fit couplings provides excellent TOOL-FREE connectivity in confined spaces.

5. No risk of fire from blow torch nor solder splatter.

6. 100& oxygen diffusion proof. Tested to DIN4726. Eliminates the risk of corrosion in metal components.

7. Excellent bending radius. Does not collapse. Guaranteed flow rate.

Premium Range is inspired by the new trends in bathrooms and kitchens and meets the needs of the market for installers, interior designers and end users.

It is a combination of design hoses and valves that fit perfectly with the different styles: rustic, minimalist, industrial, extreme...

Premium is not only a visually elegant range of products, also offers the highest quality, taking care of aspects such as water health, thanks to the anti-corrosion barrier, thus promoting its high durability. In addition, the PE-RT (Polyethylene Temperature Resistant) pipes are antibacterial and also provide extreme flexibility, which facilitates quick installation in small spaces.
The Premium Range fuses modern aesthetics with exceptional functionality.

The BUTYL 02B Flexible Stainless Steel Braided hoses are constructed from a Butyl core with a Stainless Steel braided cover and Brass fittings.

They are extensively used for the distribution of water in both Cooling and Heating applications such as Chilled Beams, Fan Coils unit, Heating systems and Pumps.

Oxygen diffusion into the pipe system increases the potential risk of corrosion and can lead to premature deterioration of ferrous metal components and wide spread system failures.

BUTYL O2B combines the ease of assembly and the highest flexibility with the oxygen diffusion resistance of a butyl in liner, tested to DIN4726.

Secure and realiable connection between a geothermal heat pump and a flow center or any other piping connection.

Oxygen Diffusion Proof

DIN 4726 TESTED

Oxygen diffusion tight. No risk of corrosion. No risk of formation of biofilm on the inner walls of the water circuit.

· According to DIN 4726, oxygen diffusion test results after thermal cycling should not exceed 0.32 mg/m2d at 40ºC. A pipe with no oxygen diffusion barrier has an oxygen permeability of more than 2g/m3.

Stress Corrosion

· For brine circuits, the use of DZR brass alloy fittings is compulsory to prevent stress corrosion

Mechanical Performance

BUTYL O2B hoses endure the original equipment mechanical life cycle and operate in a wide range of temperature and pressure environment

Installation Benefits

· Minimization of vibration and noise.

· Extremely light - Easy to handle on site.

· Polymer braid – Corrosion free and thermal insulation increased.

· Outstanding flexibility – Easy to install.

· Permanent leak-proof union. No risk of fire from blow torch nor solder splatter.
