Pipe reducer SiGMA-Li R6340 63/40 mm PP-R

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.
