ROT-GELB fittings – reliable and proven for over 60 years

We have over 60 years of experience in the production of gunmetal fittings. Over the years, we have supplied millions of our ROT-GELB fittings to HVAC wholesalers in Germany and Europe.

We say thank you to trade, crafts and industry!

We have further developed the technology of our ROT-GELB range of fittings. We would like to introduce you to the most important features on the following pages.

Tested and certified quality

HSE® fittings are developed and tested in our technical center in Berlin. All HSE® fittings are subject to constant quality and safety monitoring in accordance with current guidelines and standards.

In the first stage, the fittings undergo quality control at the factory. The second stage involves an external quality control. This involves checking both the chemical and mechanical characteristics of the fittings. The third stage takes place in our own technical center. The test protocols of the external quality control are cross-checked. We only release the fittings for sale if all three control instances show positive results.

All HSE® fittings for drinking water applications comply with the guidelines of the German Federal Environment Agency (UBA). In addition, a number of HSE® fittings have been tested and certified by the DVGW (German Technical and Scientific Association for Gas and Water).

Further advantages

VERY HIGH CORROSION RESISTANCE!
The gunmetal we use has a very high corrosion resistance, as it is particularly low in dezincification thanks to its high copper content.
ALL-ROUND QUALITIES FOR ALL WATER QUALITIES AND DEGREES OF HARDNESS!!!
Thanks to their high corrosion resistance, ROT-GELB taps are also ideally suited to a wide range of water qualities and degrees of hardness.

Even aggressive water does not affect the fittings. HSE gunmetal taps in the 3 R NEW series meet the strict requirements of the UBA (Federal Environment Agency). Model 3 R is also suitable for drinking water.
NO STRESS CORROSION CRACKING!
Stress corrosion cracking is not an issue, thanks to the very high-quality design and the high copper content in the gunmetal. The material also has a very high strength.
UNIVERSAL WORKABILITY!
ROT-GELB fittings can be combined with all known materials in pipelines, be it copper, brass, stainless steel, carbon steel or plastic.
NO PRESSURE SURGES!
The proven design of ROT-GELB fittings prevents pressure surges, which protects your pipes.
