Internal - internal thread
This category includes flexible stainless steel hoses with internal-to-internal female-female (FF) threading, designed for use in heating, plumbing, and sanitary systems. These hoses are manufactured with a braided stainless steel reinforcement layer for durability and flexibility. They are suitable for connecting components such as radiators, boilers, and heat exchangers where a compact and adaptable solution is required.
The hoses operate at a maximum temperature of +110°C and are available in pressure ratings PN 6 and PN 10, depending on size. The inner and outer diameters are specified in millimetres within parentheses on the product names. Standard lengths include 50 cm and 100 cm, with custom 30 cm and 70 cm options available upon request.
How to choose
- Select the correct nominal diameter (from 1/2" up to 6/4") based on the pipe size and flow requirements of your system.
- Ensure compatibility with PN ratings: PN 10 for sizes up to 5/4", and PN 6 for sizes 6/4" to 2".
- Confirm that the internal FF threading matches the fittings and components already installed in the system.
- Choose the appropriate length for the installation space, considering that 30 cm and 70 cm variants require special ordering.
- Verify compliance with drinking water standards if used in potable water systems; these hoses carry the relevant certification.
