Brass transitional coupling TECE 16 mm x 1/2" (model 705002)

TECE brass transitional coupling 16 mm x 1/2" (model 705002) is a metal pipe fitting designed to join 16 mm plastic or metal tubing to a 1/2" threaded connection. Made from brass to provide corrosion resistance and mechanical strength, this coupling enables a secure transition between metric tubing and imperial-threaded components in plumbing and heating systems. It is suitable for installation tasks that require a compact, durable connector between pipes and valves, taps, or radiators.

Advantages

The brass construction offers reliable corrosion resistance and durability in typical domestic and light commercial potable water and heating environments. The coupling provides a straightforward mechanical interface between 16 mm tubes and 1/2" threaded fittings, reducing the need for adapters or complex assemblies. Its compact form factor facilitates installation in confined spaces and simplifies repair or retrofit work where metric-to-threaded transitions are required.

Suitable for (tasks / use cases)

• Connecting 16 mm tubing to 1/2" threaded valves, taps or radiators
• Domestic potable water supply and plumbing repairs
• Heating system connections and radiator fittings
• Retrofit and replacement work in existing installations

Key specifications

• Material: brass for corrosion resistance and mechanical strength
• Tube connection size: 16 mm
• Threaded connection size: 1/2" (imperial)
• Function: transitional coupling between metric tubing and threaded fittings
• Typical applications: plumbing and heating installations

How to use

Install the coupling by preparing the 16 mm tube end according to the tube system requirements (cut square, deburr and, if applicable, insert any required ferrule or insert). Screw the 1/2" threaded end to the matching threaded component using appropriate sealing method for the system (for example, thread seal tape or suitable sealant) and tighten to the manufacturer-recommended torque or until a secure, leak-free joint is achieved. Verify alignment and check the assembled connection for leaks under operating pressure before completing the installation.

Usage recommendations

Use the coupling only with compatible 16 mm tubing and 1/2" threaded fittings. Confirm material compatibility with the conveyed media and system temperatures. Follow local plumbing codes and TECE installation guidelines where applicable to ensure safe and durable operation.
