Plastic pipe reducer 32/20 PP-R, pack of 50 pieces, No name R3220

PP-R pipe reducer coupling 32/20 mm supplied in a pack of 50 pieces. The fitting is designed to join polypropylene random copolymer (PP‑R) pipes with external diameters of 32 mm and 20 mm, creating a reliable mechanical and hydraulic transition between different pipe sizes. It is intended for use in potable water and heating systems where PP‑R material and compatible dimensions are specified. The pack of 50 ensures availability for larger jobs, repairs, or routine installation work.

Advantages

The PP‑R reducer provides corrosion-resistant, chemically inert connections that maintain hygienic water quality. Its uniform polypropylene construction ensures consistent thermal and mechanical properties across the joint area, reducing the risk of galvanic corrosion and material incompatibility. Supplied in a bulk pack of 50, the couplings offer efficient logistics for tradespeople and installers handling multiple connection points.

Suitable for

• Connecting 32 mm to 20 mm PP‑R pipes in domestic potable water systems
• Transitions between pipe sizes in hydronic heating circuits
• Plumbing repairs and retrofit work requiring standard PP‑R fittings
• Stocking for professional plumbing and maintenance teams

Key specifications

• Material: polypropylene random copolymer (PP‑R)
• Connection type: socket/heat-fused coupling
• Compatible pipe outer diameters: 32 mm and 20 mm
• Pack quantity: 50 pieces
• Application: potable water and heating systems (where PP‑R is specified)

How to use

Prepare pipe ends by cutting square and removing burrs to ensure full insertion. Follow standard heat-fusion (socket fusion) or installation procedures appropriate for PP‑R couplings: heat the pipe and fitting to the recommended temperature, insert the pipe to the marked depth, hold until the joint cools and solidifies, and then allow the assembly to reach ambient temperature before pressurising. Observe manufacturer and local plumbing codes for joint preparation, fusion parameters and safety precautions.

Usage recommendations

Store fittings in a dry, shaded area away from direct sunlight and extreme temperatures. Use appropriate fusion tools calibrated for PP‑R materials and verify compatibility with the pipe SDR/class. For potable water and heating installations, follow local regulations and test the system for leaks and correct operation after cooling and pressurisation.
