TECE soldering fitting TECEFLEX coupling for flexible/copper pipe 2022, model 713920

TECE soldering fitting TECEFLEX coupling for flexible/copper pipe 2022 (model 713920) is a plumbing coupling designed to join TECEFLEX flexible lines with standard copper pipework by means of a permanent soldered joint. The fitting provides a reliable transition between flexible and rigid piping in water and heating systems when installed and soldered following accepted plumbing procedures. Its design supports secure connections in repair and installation tasks where compatibility between materials is required.

Advantages

The coupling is engineered to enable a durable soldered connection between flexible TECEFLEX lines and copper pipes, reducing the risk of leaks when assembled properly. Its geometry and wall thickness are adapted for reliable heat transfer during soldering and for stable mechanical performance in service. The component is suitable for professional use and repair works, offering a straightforward solution for transitions between flexible and copper piping without the need for additional adapters or complex fittings.

Suitable for

• Connecting TECEFLEX flexible pipes to copper supply lines in potable water systems
• Transitions between flexible and copper piping in heating installations
• Plumbing repair work where a permanent soldered joint is required

Key specifications

• Function: soldering coupling for joining flexible and copper pipes
• Application: water and heating installations
• Material compatibility: designed for use with TECEFLEX flexible lines and copper piping
• Connection type: permanent soldered joint
• Design purpose: transition fitting between flexible and rigid pipework

How to use

Prepare both the TECEFLEX flexible pipe and the copper pipe by cutting squarely and removing any burrs or oxide layers. Slide the coupling onto the cleaned copper pipe end and position the TECEFLEX flexible line into the opposite side according to the manufacturer’s recommendations for insertion depth. Apply suitable flux to the joint surfaces, heat the coupling evenly with an appropriate soldering torch or heater until flux activation and solder flow occur, and feed solder to form a continuous fillet ensuring complete wetting of the joint. Allow the assembly to cool naturally and then inspect the joint for complete solder coverage and absence of visible defects before placing the system into operation.

Usage recommendations

Use approved flux and solder materials compatible with potable water and heating systems and follow local plumbing codes. Ensure correct support and restraint of piping to avoid mechanical stress on the soldered joint. If unsure about installation or suitable materials, consult a qualified plumber or refer to TECE installation guidance.
