## Summary description

VIEGA 4712 is a Pexfit threaded coupling designed for joining 20 mm plastic piping to a 3/4" threaded connection. The fitting provides a transition between PEX systems and standard threaded fixtures or valves. Suitable for potable water and heating installations where a reliable mechanical threaded connection is required.

## Long description

VIEGA 4712 threaded coupling 20 x 3/4" Pexfit is a transition fitting engineered to connect 20 mm PEX (plastic) piping to a 3/4" external threaded connection. The coupling is intended for use in potable water and heating installations where a secure mechanical thread interface is required between PEX distribution lines and standard threaded valves, taps or components. The design supports a straightforward connection between flexible plastic piping systems and conventional threaded fixtures.
Advantages
The coupling offers a compact, durable solution for transitioning from 20 mm PEX piping to a 3/4" threaded connection without the need for soldering or complex adapters. Its construction ensures leak-resistant performance when installed according to manufacturer guidelines, and it maintains compatibility with typical potable water and heating system materials. The product reduces installation time while providing a stable threaded joint compatible with common valves and fixtures.
Suitable for
Joining 20 mm PEX piping to 3/4" threaded valves or taps
Potable water distribution in residential and commercial buildings
Heating system connections where a mechanical thread transition is required
Repair or replacement of threaded components on PEX piping runs
Key specifications
Connection 1: 20 mm PEX push-fit/insert compatible
Connection 2: 3/4" external threaded connection
Material: corrosion-resistant fitting materials suitable for potable water
Designed use: potable water and heating applications
Installation type: mechanical threaded transition for PEX systems
How to use
Prepare the PEX pipe by cutting square and deburring the end, then insert according to Pexfit recommendations to ensure full engagement. Thread the 3/4" mating component onto the coupling and tighten to the appropriate torque specified for the threaded connection, using standard sealing methods for threads if required by the installation (for example, suitable thread sealant or tape). Verify alignment and secure pipe supports to avoid stress on the joint. Pressure-test the system after installation to confirm a leak-free connection.
Usage recommendations
Use the coupling only with compatible 20 mm PEX piping and 3/4" threaded components. Follow local codes and VIEGA installation instructions for potable water and heating systems. Avoid over-tightening the threaded connection and ensure proper pipe support to maintain long-term mechanical integrity.
