Plastic push-fit connector Uponor Prestee Unipipe np 16 mm × 1/2" × 16 mm

Uponor Prestee Unipipe np 16 mm × 1/2" × 16 mm is a plastic push-fit connector designed to join 16 mm polymer piping with a 1/2" threaded appliance or valve. The compact fitting provides a watertight transition between push-fit pipe ends and a central female/male threaded section, enabling easy connection to fixtures or valves used in potable water and heating systems. Constructed for use with 16 mm Unipipe systems, the connector aims to simplify installation where a threaded interface is required.

Advantages

The connector offers quick push-fit installation on both 16 mm pipe ends and a reliable threaded interface in the center, reducing the need for additional adapters. Its plastic construction resists corrosion and mineral buildup while remaining lightweight. The design supports potable water and heating applications, providing a sealed joint without soldering or complex tools. Compact dimensions make it suitable for installations in confined spaces.

Suitable for

• Connecting 16 mm polymer supply pipes to 1/2" threaded valves, taps or appliances
• Domestic potable water distribution systems
• Small heating circuits and radiator connections where a threaded transition is needed
• Retrofit or repair jobs requiring a compact, push-fit to threaded adapter

Key specifications

• Pipe connection size: 16 mm push-fit at both ends
• Threaded connection: 1/2" central threaded section for appliance or valve
• Material: plastic polymer suitable for water contact
• Application: potable water and heating systems
• Installation type: push-fit on pipe ends, threaded middle connection
• Compact form factor for tight installation spaces

How to use

Prepare the 16 mm polymer pipes by cutting squarely and deburring the ends. Push each pipe end firmly into the push-fit sockets until it reaches the stop; ensure the pipe is fully inserted to create a proper seal. Screw the 1/2" threaded appliance or valve onto the central threaded section, using appropriate thread sealant or tape if required by the installation standard. Verify the assembly for leaks by pressurizing the system according to local codes and inspect all joints visually.

Usage recommendations

Use compatible 16 mm Unipipe or equivalent polymer pipes. Follow local plumbing and heating regulations for thread sealing and pressure testing. Avoid excessive bending near the connector and confirm temperature and pressure ratings of the overall system are within the limits of the piping and fittings used.
