## Summary description

Metal threaded connector from WAVIN, model 4064266, designed for joining 20 mm PEXAL/TIGRIS pipe to a 3/4" threaded fitting. Intended for plumbing and heating installations, this coupling provides a threaded transition between polymer pipe and standard 3/4" male/female threads. Suitable for water supply and central heating systems where PEXAL/TIGRIS tubing is used.

## Long description

WAVIN metal threaded connector 20 x 3/4" for PEXAL/TIGRIS is a brass transition coupling designed to connect 20 mm PEXAL or TIGRIS polymer piping to standard 3/4" threaded fittings. Intended for plumbing and heating installations, this connector provides a reliable mechanical and sealed interface between flexible multicore pipe and metal-threaded valves, radiators or other fittings used in water supply and central heating systems.
Advantages
The metal construction ensures mechanical strength and resistance to deformation under tightening torque. The threaded 3/4" end allows direct connection to common valves and fixtures without additional adapters, while the 20 mm side fits onto PEXAL/TIGRIS pipe with a compression or securing method compatible with the pipe system. The design supports installation in confined spaces and provides a compact transition while maintaining flow characteristics appropriate for domestic water and heating circuits.
Suitable for
 Connecting 20 mm PEXAL or TIGRIS pipe to 3/4" threaded valves and fixtures
 Domestic and commercial water supply lines
 Central heating pipework and radiator connections
 Repairs or retrofits where polymer pipe meets standard threaded fittings
Key specifications
 Pipe connection size: 20 mm (suitable for PEXAL/TIGRIS 20 mm tubing)
 Threaded connection: 3/4" standard pipe thread
 Material: metal (brass or brass alloy construction typical for WAVIN fittings)
 Application: potable water and central heating systems
 Connection type: transition coupling from polymer pipe to threaded fitting
How to use
Prepare the PEXAL/TIGRIS pipe by cutting squarely and inserting any required sleeve or insert according to the pipe system's installation instructions. Slide the connector onto the pipe and secure using the compatible compression ring or crimping method recommended for the PEXAL/TIGRIS system. Tighten the 3/4" threaded end onto the mating fitting using an appropriate wrench, ensuring not to overtighten. Perform a pressure test after installation to verify there are no leaks at either the polymer or threaded interface.
Usage recommendations
Use suitable sealing materials on the 3/4" thread if required by the fitting type; follow WAVIN or system-specific guidance for insert placement and compression/crimping torque to ensure a durable, leak-free connection in potable water and heating applications.
