Compression Straight Coupling TECE 16 mm — TECE 706016

TECE 16 mm compression straight coupling is a compact plumbing fitting designed to join two 16 mm pipes in a direct straight connection. Manufactured by TECE for potable water and heating installations, the coupling provides a reliable mechanical seal suitable for repairs, extensions and new plumbing runs in residential and commercial projects. The fitting is intended for use where a simple, space-efficient inline connection is required without changing pipe alignment.

Advantages

The compression straight coupling offers secure, leak-resistant joints without soldering or specialized tools, enabling fast installation. Its compact design minimizes space usage in tight pipe runs and behind fixtures. Materials and dimensions are chosen to meet common plumbing system requirements for drinking water and heating circuits, ensuring compatibility with standard 16 mm piping. The coupling is reusable in many cases when disassembled correctly, which supports maintenance and system modifications.

Suitable for

• Connecting two 16 mm pipes in a straight line
• Repairing damaged sections of potable water or heating piping
• Extending existing 16 mm pipe runs in renovation projects
• Installing compact inline connections behind fixtures and in service cabinets

Key specifications

• Pipe size compatibility: 16 mm
• Connection type: compression straight coupling for inline joints
• Application: potable water and heating systems
• Form factor: compact, inline coupling suitable for limited space

How to use

Prepare pipe ends by cutting square and deburring the inner and outer edges. Slide the compression nut and compression ring (ferrule) onto each pipe as required, insert pipes fully into the coupling body until they meet the internal stop, then tighten the compression nuts by hand and finish with a wrench to the manufacturer's recommended torque or until the joint is secure. Check the connection for leaks by pressurizing the system and retightening if necessary. Follow local plumbing codes and standard safety practices during installation.

Usage recommendations

Use the coupling with compatible 16 mm pipes and fittings; avoid overtightening to prevent deformation of the compression ring. For long-term reliability, verify that materials used in the system are suitable for potable water and heating temperatures. When in doubt, consult installation guidelines for the specific pipe material and local regulations.
