## Summary description

SiGMA-Li PERTZW2034T is a welded compression fitting designed for PE-RT pipes with a 20 mm outside diameter and a 3/4" threaded GW (female) connection. Intended for plumbing and heating installations, it provides a secure welded joint between PE-RT tubing and threaded fixtures. Suitable for potable water and central heating systems where a reliable transition to a 3/4" female thread is required.

## Long description

SiGMA-Li PERTZW2034T is a welded compression fitting engineered for use with PE-RT pipes that have a 20 mm outside diameter. It provides a transition from PE-RT tubing to a 3/4" female threaded connection suitable for plumbing and heating systems. The fitting is designed to create a welded, leak-resistant joint that integrates plastic pipework with threaded fixtures used in potable water and central heating installations.
Advantages
The welded compression design ensures a durable, low-maintenance connection between PE-RT pipe and a 3/4" female thread. Compatibility with standard 20 mm PE-RT tubing simplifies installation planning and reduces the need for additional adaptors. The fitting is suitable for use in potable water and heating circuits where a secure transition from plastic pipe to metal-threaded components is required.
Suitable for
Domestic potable water supply lines using 20 mm PE-RT pipe
Central heating system connections and manifolds
Transition points where PE-RT tubing connects to 3/4" threaded valves or appliances
Repair or retrofit works requiring a welded compression to threaded joint
Key specifications
Pipe compatibility: PE-RT with 20 mm outside diameter
Connection type: welded compression to 3/4" female (GW) threaded outlet
Application: potable water and central heating systems
Material properties: designed for plastic-to-thread transition and resistance to common plumbing stresses
How to use
Prepare the PE-RT pipe by cutting squarely and deburring the end to ensure full insertion into the fitting. Slide the pipe into the welded compression fitting until it seats fully, then perform the recommended welding or connection method specified for the fitting and pipe material to create a permanent joint. Once the plastic connection is made, attach the mating 3/4" female threaded fixture and tighten to the torque appropriate for the fixture material and thread seal method. Verify that the assembled joint is correctly aligned and pressure-test the system according to applicable plumbing or heating standards.
Usage recommendations
Use appropriate tools for cutting and deburring PE-RT pipe and follow manufacturer guidance for welding or joining procedures. Apply suitable thread sealing (e.g., PTFE tape or approved sealant) on the 3/4" thread where required, and perform a pressure test after installation to confirm leak-free operation. Ensure the fitting is used within the temperature and pressure ratings of the PE-RT pipe and the overall system.
