Fitting elbow SiGMA-Li SIGMA LI Kolano zgrzewane GZ 25x3/4 PE-RT

Fitting elbow SiGMA-Li SIGMA LI Kolano zgrzewane GZ 25x3/4 PE-RT is a welded elbow designed for PE-RT piping systems. It provides a 90° direction change and joins a 25 mm PE-RT pipe to a 3/4" threaded connection, offering compatibility with welded PE-RT installations for heating, potable water and other low-pressure applications. The component is intended to create a secure, leak-resistant transition between plastic pipeline and threaded fittings where a right-angle turn is required.

Advantages

The welded design ensures a consistent fusion joint that minimizes potential leak paths and maintains mechanical strength at the elbow. Compatibility with PE-RT materials preserves system integrity and thermal stability. The 25 mm to 3/4" configuration simplifies transitions to standard threaded fixtures, reducing the need for additional adapters. Overall, the fitting offers straightforward installation and durable performance in typical low-pressure circuits.

Suitable for

• Residential and commercial heating circuits using PE-RT piping
• Potable water distribution systems operating at low pressure
• Transitions from PE-RT pipe to standard 3/4" threaded fixtures
• Right-angle routing in tight installation spaces

Key specifications

• Material compatibility: PE-RT pipe systems
• Connection types: 25 mm welded PE-RT socket to 3/4" external threaded connection
• Angle: 90° elbow
• Typical application pressure: suitable for low-pressure circuits (heating and potable water)
• Usage environment: indoor piping and concealed installations

How to use

Prepare the PE-RT pipe by cutting it square and cleaning the pipe end according to the PE-RT welding procedure. Use an appropriate socket fusion or electrofusion welding method recommended for PE-RT materials to create a secure welded joint between the pipe and the elbow socket. Thread the 3/4" external connection into the corresponding female threaded fixture or use suitable sealing tape or paste as required to ensure a leak-free threaded connection. After assembly, follow pressure testing and system commissioning procedures appropriate for the installed piping system.

Usage recommendations

Ensure welding is performed by trained personnel using equipment calibrated for PE-RT fusion. Verify compatibility of the threaded mating components and apply correct sealing practice for the 3/4" thread. Perform pressure testing after installation to confirm joint integrity and follow local regulations and standards for potable water and heating installations.
