TIVENTO Flex esieristetty kupariputki 1/4" (6,35 mm) - 50 m rulla

For refrigeration and air conditioning installers who need to run lines without fuss, the TIVENTO Flex pre-insulated copper pipe delivers in a single, continuous 50-meter coil. This is not just a plain copper tube—it arrives already wrapped in closed-cell polyethylene foam, saving you strapping and insulation time on the job.

Why choose it

The integrated vapor barrier stops moisture from entering the insulation, which is critical in low-temperature systems to prevent ice build-up and efficiency loss. The copper is clean, dry, and deoxidized, and sealed end caps keep contaminants out until you're ready to use it. You can pull your lines faster and with better protection than ever.

Ideal use cases

• Split air conditioning installations
• Refrigeration line sets
• Heat pump connections
• HVAC system piping

Good to know

This pipe is designed for high-pressure refrigerants and is suitable for both liquid and suction lines. The 1/4 inch outer diameter is a common size for smaller capacity units. The insulation meets strict fire safety standards, so you can use it in exposed areas with confidence.
