PP-R pipe fitting sleeve 50 mm, Sony M50, pack 1 (10 pcs)

PP-R pipe fitting sleeve 50 mm, Sony M50 is a coupling designed to join polypropylene random copolymer (PP‑R) pipes with a 50 mm nominal diameter. Supplied in a pack of 10 pieces, this sleeve is intended for creating permanent fusion joints in plumbing and heating installations. It is compatible with standard PP‑R welding and electrofusion methods and is suitable for use in potable water distribution and heating circuits when installed according to applicable standards and with correct equipment.

Advantages

The Sony M50 coupling sleeve provides a uniform, leak‑resistant connection by enabling heat fusion between matching PP‑R pipe ends. Its polypropylene construction ensures chemical resistance to common water additives and corrosion‑free performance compared with metal fittings. Supplied in a pack of ten, the sleeves offer convenience for medium‑scale installation jobs and spare parts stocking. The coupling’s design supports reliable hydraulic sealing and retains the full pressure rating of the joined pipe when welded correctly.

Suitable for

• Joining 50 mm PP‑R pipes in potable water supply systems
• Connecting sections in residential and commercial heating circuits
• Repairing or extending existing PP‑R piping installations
• Use with socket fusion or electrofusion tools suitable for PP‑R materials

Key specifications

• Material: polypropylene random copolymer (PP‑R)
• Nominal diameter: 50 mm
• Pack quantity: 10 pieces per package
• Connection method: fusion welding (socket fusion or electrofusion compatible)
• Typical applications: potable water and heating systems

How to use

Prepare pipe ends by cutting square and removing burrs, ensuring cleanliness and dryness. Select fusion equipment appropriate for PP‑R pipes and follow the tool manufacturer’s temperature and time settings. Heat the pipe ends and the inner surface of the coupling sleeve uniformly, then insert the pipe to the marked depth and hold steady until the joint cools to ambient temperature. After cooling, verify alignment and perform a pressure test in accordance with local installation codes and standards before commissioning.

Usage recommendations

Store the sleeves in a dry, dust‑free environment away from direct sunlight prior to use. Use only certified PP‑R welding tools and follow relevant standards for potable water and heating installations. Do not attempt mechanical compression joins or solvent welding methods not intended for PP‑R materials; ensure joints are allowed to cool fully before pressurization to achieve rated performance.
