Suitable for hot and cold water installations where PP-R fittings are used; welded or socketed installation with compatible tools.

## Long description

SiGMA-Li R6340 63/40 mm PP-R pipe reducer is designed to connect polypropylene random copolymer (PP-R) pipes of different diameters, providing a smooth internal transition from 63 mm to 40 mm. The fitting is intended for use in plumbing and heating systems where PP-R components are used, allowing for reliable flow and pressure performance in both hot and cold water installations. It is compatible with standard socket fusion and welding tools used for PP-R systems.
Advantages
The reducer offers a uniform internal surface to minimise turbulence and scale accumulation, and it is manufactured from PP-R material that resists corrosion and many common chemicals. Its construction supports reliable sealing when properly welded, ensuring leak-resistant joints in potable water and heating networks. The compact design simplifies routing in confined spaces and reduces the need for additional adapters.
Suitable for
Domestic and commercial hot water distribution
Cold water supply systems
Heating circuit connections where diameter reduction is required
Plumbing installations using PP-R piping and fittings
Key specifications
Material: polypropylene random copolymer (PP-R)
Connection type: socket fusion / welding compatible
Nominal diameters: transition from 63 mm to 40 mm
Suitable media: hot and cold water
Typical operating temperature range: suitable for standard PP-R system temperatures
How to use
Prepare pipe ends by cutting them square and removing any burrs or debris. Mark insertion depth on the pipe according to the fitting dimensions. Use a compatible PP-R socket fusion tool or welding equipment to heat the pipe and fitting surfaces to the required temperature, then insert the pipe into the fitting and hold until the joint cools to form a secure, homogeneous connection. Allow sufficient cooling time before pressurising the system and follow relevant installation standards and safety procedures.
Usage recommendations
Before installation, verify material compatibility and pressure/temperature ratings for your specific system. Use certified fusion tools and follow manufacturer guidelines for heating temperatures and joint cooling times to ensure durable, leak-free connections.
