Applicable certifications pertaining to various dimensions will be gathered from the tables listed below.

flexibility & protection for heating and air-conditioning

Due to its oxygen impermeability O₂Stopp is ideally suited for the connection of:

Caution >> For plug connections different operating pressures and temperatures apply!

1. standard connection fittings nickel-plated brass / blank or custom-made
2. ferrule made of stainless steel AISI resp. made of aluminium as of DN 15
3. flexible and mechanically resilient ethylene-propylene-dien-caotchouc (Butyl)
4. high-quality braiding made of stainless steel AISI upon request also other braiding materials possible

The hose material O₂Stop stands out for its excellent mechanical resilience and its high thermal resistance. It is most flexible and easy to install. The material has been examined for its oxygen diffusion behaviour acc. to DIN 4726. In order to be classified as oxygen impermeable acc. to DIN a maximum of 0,1 g of oxygen per m³ and per day is licit to diffuse into the inside of the hose. O₂Stop undercuts this limit by more than half with an amount of only 0,04 g of oxygen per m³ and per day.

The exclusion of oxygen stops corrosion as well as the growth of bacteria and consequently prevents the silting in heating and air-conditioning systems.

measurements in mm. All quotations (excluding diameter) are minimum measurements and shall be exceeded when possible.

The guarantee shall apply only if the directions mentioned above are observed exactly as well as the installation has been carried out professionally and in accordance with current regulations. Corrosive, electro-chemical and bacteriological strain shall be avoided by appropriate protection measures. Errors and changes for technical progress excepted. Publication of current issue renders previous editions invalid.
