The Quick-lock fittings is an innovative solution for quickly forming threaded ends of metal hoses without welding. It provides a reliable, leak-proof and durable connection without the need for special tools or complicated installation.
Main purpose
The Quick-lock fittings is used for:
- installation of stainless steel metal hoses in heating, water supply, air conditioning, solar systems, industrial installations;
- forming threaded connections without the need for welding or press tools;
- quick repair or retrofitting of already installed systems.
Advantages of Quick-lock fittings
- Quick and easy installation – installation of the coupling does not require welding equipment or special tools.
- Reliability and strength of the connection – the sealed connection withstands high loads and vibrations.
- Reusability – the coupling can be disassembled and reused without losing its properties.
- High temperature resistance – stable operation at temperature up to +280°C.
- Pressure resistance – withstands operating pressure up to 30 bar, which allows it to be used in high-temperature and high-pressure systems.
Advantages of use in Eco-Flex systems
With the Quick-lock fittings, you can independently manufacture hoses of any length from Eco-Flex metal hoses, while ensuring complete tightness and safety of connections.
The Quick-lock fittings is a convenient, reliable and cost-effective solution that simplifies the installation of metal hoses and guarantees long-term trouble-free operation of systems.
