## Summary description

Welded T-fitting USMetrix Trójnik GZ for PE-RT and polyethylene piping, model PERTTZ2512. Designed for connecting a 25 mm PE-RT/PE main line with a 1/2" threaded branch.

Commonly used in potable water, underfloor heating, and distribution manifolds.

## Long description

Welded T-fitting USMetrix Trójnik GZ welded PE-RT/PE 25x1/2 (PERTTZ2512) is a plastic pipe fitting designed to connect a 25 mm PE-RT or polyethylene main line to a 1/2" threaded branch. Manufactured for plumbing and heating systems, the fitting combines a welded plastic connection for the main run with a metal-threaded outlet, enabling transition between continuous plastic piping and standard threaded components such as valves, meters or accessories. The design accommodates potable water, underfloor heating circuits and distribution manifolds where a secure sealed junction is required.
Advantages
This USMetrix welded T-fitting provides a secure welded connection on the 25 mm plastic run and a standardized 1/2" threaded branch for durable mechanical joining. The combination of PE-RT/PE welding compatibility and a threaded outlet reduces the need for additional adapters and simplifies installation in mixed-material systems. The fitting is intended for use in systems that require a reliable watertight joint and easy integration with threaded fittings and meters.
Suitable for
Domestic and commercial potable water distribution
Underfloor heating manifolds and branch connections
Plumbing installations requiring a transition from plastic pipe to threaded valve or meter
Repair or extension of PE-RT/PE piping networks
Key specifications
Main pipe connection: for 25 mm PE-RT / polyethylene (welded joint)
Branch connection: 1/2" external thread (male)
Material compatibility: PE-RT and common polyethylene piping
Application areas: potable water, heating circuits, distribution manifolds
Connection types: welded plastic connection and threaded metal outlet
How to use
Prepare the 25 mm PE-RT or polyethylene main pipe by cutting squarely and cleaning the pipe end to remove debris and oxidation. Perform the welding procedure recommended for PE-RT/PE fittings—typically socket or butt fusion or an approved welding method for this type of fitting—ensuring proper temperature and pressure parameters according to installer guidelines. Once the plastic run is welded and cooled, thread the 1/2" mating component onto the branch using appropriate thread sealant or tape on the male thread if required by the downstream component and local codes. Check the assembled junction for alignment and tightness, and perform pressure testing of the system following applicable standards before putting into regular operation.
Usage recommendations
Use certified welding equipment and follow PE-RT/PE welding best practices. Verify material compatibility and thread sealing method for the connected 1/2" component. Perform pressure and leak tests after installation and follow local plumbing and heating regulations.
