Uponor press fitting with female thread 16 mm – Rp 1/2 (model 1014536)

Uponor press fitting with female thread 16 mm – Rp 1/2 is a press-join adapter developed for 16 mm tubing, providing an internal Rp 1/2 threaded outlet for valves, fixtures and adapters. The fitting is intended for use in plumbing and heating systems and is compatible with press-joining installation methods used for PEX and metal-composite pipes. Its design ensures a compact transition from press-joined pipework to a standard Rp 1/2 threaded connection without additional sealing operations when installed correctly.

Advantages

The fitting enables a reliable, leak-resistant transition between press-joined 16 mm pipe runs and Rp 1/2 threaded components. It is manufactured to meet common requirements for potable water and heating installations and is suitable for use with compatible pressing tools and jaws. The press joint forms a permanent mechanical connection that reduces installation time compared with traditional soldering or adhesive methods while maintaining a low-profile appearance and secure thread interface for downstream fittings.

Suitable for

• Connecting 16 mm PEX or metal-composite pipework to Rp 1/2 threaded valves and fixtures
• Domestic potable water distribution and secondary heating circuits
• Retrofit and renovation projects requiring a threaded outlet from press-joined piping

Key specifications

• Pipe connection size: 16 mm press socket suitable for PEX and metal-composite pipes
• Thread type: internal Rp 1/2 (BSP parallel internal thread)
• Material: corrosion-resistant metal suitable for potable water and heating applications
• Connection method: press-join for use with compatible pressing tools and jaws
• Operating environments: cold and hot water distribution, secondary heating systems

How to use

Prepare the 16 mm pipe by cutting square and deburring the end to the manufacturer’s recommended dimensions. Slide the press fitting onto the prepared pipe until it seats fully against the stop. Position the correct press jaw over the fitting and operate a compatible pressing tool to complete the press connection according to the tool and fitting manufacturer instructions. Once pressed, the internal Rp 1/2 thread accepts standard Rp 1/2 threaded components; use the appropriate thread sealant or tape only when required by the downstream component specification.

Usage recommendations

Ensure use of pressing tools and jaws that are approved for this type of fitting and follow the applicable installation standards. Confirm pipe compatibility (PEX or metal-composite) and observe recommended working pressures and temperatures for the system. Avoid applying mechanical stress to the joint immediately after pressing and test the system for leaks before final commissioning.
