Product information

Description

SiGMA-Li PERTTW2534 is a welded compression tee designed for PE-RT piping systems, providing a 25 mm to 3/4" branch connection. Intended for use in hot- and cold-water distribution and underfloor heating installations, this fitting allows creation of reliable branch lines with material compatibility for PE-RT pipes. The design focuses on secure welded joints and consistent flow characteristics to integrate with standard PE-RT plumbing layouts.

Advantages

The welded tee construction ensures a strong, leak-resistant junction between the main PE-RT run and the 3/4" branch, reducing the risk of failures at connection points. Compatibility with PE-RT material eliminates dissimilar material stress and supports uniform thermal expansion, while the compression-style interface simplifies installation where welding or fusion to the branch is required. The compact geometry conserves space and helps maintain hydraulic performance in distribution manifolds and heating circuits.

Suitable for

  • Creating branch lines from 25 mm PE-RT mains to 3/4" fixtures or manifolds
  • Hot- and cold-water distribution systems in residential and commercial buildings
  • Underfloor heating installations using PE-RT piping
  • Repair or extension of existing PE-RT pipe networks requiring a welded tee connection

Key specifications

  • Connection sizes: 25 mm (main) to 3/4" (branch)
  • Fitting type: welded tee for PE-RT piping systems
  • Material compatibility: PE-RT
  • Application: potable water distribution and underfloor heating
  • Installation method: welded/fusion connection on PE-RT main with compression-compatible branch interface

How to use

Prepare straight, clean pipe ends and ensure PE-RT surfaces are free of debris or oxidised layers before welding. Align the 25 mm PE-RT main into the tee body and perform the appropriate weld or fusion process according to PE-RT welding guidelines and local standards. Connect the 3/4" branch side using the compatible compression or threaded interface as specified for the installation, checking for correct alignment and full engagement. After assembly, perform pressure and leak tests in line with applicable regulations and allow any welded joints to cool and stabilise before system commissioning.

Usage recommendations

Use only with PE-RT piping and follow manufacturer and local codes for welding parameters, pressure testing, and thermal cycling. Verify compatibility with any valves, manifolds, or fittings attached to the 3/4" branch and avoid exposing joints to mechanical stress during curing. Routine inspection after commissioning is recommended to confirm leak-free performance.
