The product is intended for use in repair work, retrofits and new installations where a reliable, space-efficient interface is required.

Advantages

The fitting delivers a secure mechanical connection between a 16 mm pipe and a 3/4" male thread, minimizing the need for additional adapters. Its compact form factor reduces installation space and simplifies routing near appliances, valves or manifolds. The design supports quick assembly and is compatible with standard plumbing practice for potable water lines when installed according to local codes.

Suitable for

• Connecting 16 mm water supply pipes to appliances with a 3/4" male thread
• Repair and replacement tasks on residential water installations
• Retrofitting valves, mixers or filters that require a 3/4" threaded inlet
• Plumbing runs in confined spaces where a compact interface is needed

Key specifications

• Pipe connection size: 16 mm
• Thread type: 3/4" female thread (compatible with 3/4" male fittings)
• Application: water supply plumbing for residential and light commercial use
• Form factor: compact inline adapter for direct pipe-to-thread transition

How to use

Prepare the 16 mm pipe by cutting squarely and deburring the end. Insert the pipe into the connection according to the manufacturer's installation method for the chosen pipe material (push-fit, compression or bonded joint as applicable). Hand-tighten the 3/4" male threaded mating part and finish with the appropriate tool to the recommended torque, ensuring sealants or sealing tape are applied where required by local practice. After installation, check for leaks by pressurizing the system and inspect the joint under normal operating conditions.

Usage recommendations

Use compatible sealing materials and follow local plumbing codes. Verify material compatibility with the installed pipe and connected equipment. Where applicable, follow the TECE installation guidance for connections and perform a pressure test after assembly.
