## Long description

SiGMA-Li ZN repair kit for PP-R piping systems is a compact set of components intended for repairing or replacing damaged sections and joints in polypropylene random copolymer (PP-R) plumbing networks. The kit is designed to allow targeted on-site restoration of plastic pipes and fittings without the need to remove or replace long runs of piping, helping to restore water or heating system integrity quickly and with minimal disruption.
Advantages
The repair kit provides a practical combination of parts compatible with PP-R materials, enabling precise replacement of worn or damaged segments. Its components are suitable for use in both domestic and commercial installations where PP-R pipes are present. The kit reduces installation time compared with full-pipe replacement and supports reliable connections when installed according to standard joining methods for polypropylene systems.
Suitable for
Repairing damaged sections of PP-R domestic plumbing
Restoring joints and fittings in commercial plastic piping systems
On-site emergency patching of hot and cold water lines using PP-R materials
Maintenance work in heating circuits that use PP-R pipes
Key specifications
Material compatibility: polypropylene random copolymer (PP-R)
Application: local repair and replacement of pipe sections and joints

Intended for mechanical and thermal fusion joining methods typical for PP-R systems
Compact kit size for on-site use and storage
How to use
Select the damaged section and isolate the affected circuit by shutting off water supply and relieving pressure. Cut out the defective pipe or joint and prepare pipe ends by cleaning and ensuring square cuts. Fit replacement components from the kit using the appropriate joining method for PP-R systems — for example, thermal fusion/welding or compatible mechanical connectors specified for PP-R. Allow joints to cool and cure as required by the chosen joining technique, then restore supply and check for leaks.
Usage recommendations
Follow relevant local plumbing codes and manufacturer instructions for PP-R joining procedures. Use certified fusion tools or approved connectors and verify compatibility of all replacement parts with existing PP-R materials. After installation, perform a pressure test before returning the system to regular operation.
